Speeding up your PC


Are you a victim of slow-PC syndrome? Do you wish your computer boots up Windows in seconds instead of minutes? Well fear not, you’re not alone! Many people have this issue and it can be remedied by several simple and proactive steps. In this Tech Tip, we examine 10 simple ways to quickly speed up your computer regardless if it’s a laptop or desktop.


1.) Turn off unnecessary programs during start-up.

Click START – RUN – and type “msconfig” – click STARTUP tab - uncheck the programs that are not needed upon startup such as ADOBE ACROBAT, GOOGLE UPDATE, QUICKTIME – You can see the program name, its file extension and location by the Manufacturer, Command and Location, respectively.
WARNING – IF YOU’RE UNSURE ABOUT A CERTAIN PROGRAM,DO NOT UNCHECK IT AS IT CAN HAVE UNPLEASANT CONSEQUENCES. ONLY UNCHECK THE PROGRAMS THAT YOU RECOGNIZE AND DO NOT NEED TO HAVE RUNNING AT START-UP (i.e. WINAMP AGENT)


2.) Use a free cleaning utility to clean out your system.

Free programs like C Cleaner delete old junk files, cached pages, temporary files and other unimportant data from your computer, thus freeing up your hard drive. If you’re looking for an all-in-one solution,Tune Up Utilities is an excellent program that can tackle all things cleaning-related so you don’t have to use multiple programs to clean your computer. C Cleaner also has a Windows Registry cleaning feature that can help clean out your registry for increased performance.


3.) Upgrade your computers hard drive to a new/bigger/faster one!

Hard drives are getting faster, cheaper and bigger so pick up a new one! Whether your current one is old, sputtering on its last spindle rotation, or almost at full capacity, you can purchase a 500GB, 750GB or 1 Terabyte drive that has much more buffer cache, faster spindle speeds and can even consume less power! (eco-green models) Even if your current drive is working fine, a second hard drive is handy as a large dumping ground for files or can serve as a place to store back-up images of your current hard drive. If you don’t feel like cracking open your case, you can opt for an external hard drive and dump your archive files there to free up space. The reason is because as a hard drive gets full, its performance decreases because it has to work harder to access files.


4.) More Computer Memory (RAM) Scotty!

Now is the time to buy RAM/Memory if your computer was built within the last 5 years. The prices of DDR2 and DDR3 RAM have gone down significantly so it would be in your best interest to pick up at least 1-2 GB on top of what you have now. More RAM means that the computer can do a better of job of booting up programs, delegating tasks and increase overall system performance. Check with your respective PC manufacturer to determine how much RAM you computer can accommodate.


5.) Utilize Anti-Virus, Anti-Spyware and Anti-Malware programs

It’s not rocket science that if your computer is infected with a Trojan, botnet or other type of malicious infection, it can slow down your computer considerably. (And possibly compromise your IT security) Pick up a good anti-virus program like MS Security Essentials or AVG Antivirus if you fancy free versions. If you don’t want to have your system hijacked by a Trojan, pick up Malwarebytes’ Antimalware which can find and quickly eliminate programs such as “Avira AV” which auto-install and trick the unsuspecting victim that he/she is infected. (Then it will try to collect payment from “product activation” but it’s really just a hijacking program) Bottom line, your computer will run faster and much more efficient without these kinds of infections.


6.) Update Drivers

This obviously sounds like a chore but keep in mind that with the super fast pace of technology, having the most up-to-date software is important for a computer’s stability, compatibility and performance. For example, if you play PC games or do heavy graphics editing, your gaming/editing performance might suffer if you’re using outdated drivers from the video card manufacturer. (Or OEM PC maker)


7.) Take advantage of READYBOOST!

If you’re running Windows Vista or 7, utilizing ReadyBoost is one of the simplest speed tweaks you can perform! Just pick up a 2-4 GB USB flash drive, plug it into your computer and wait for it to be recognized. Afterwards, right click on the flash drive letter under My Computer and click the READYBOOST tab. Check USE THIS DEVICE and click OK and voilá! You’re done!


8.) Turn off User Account Control (UAC) and Aero

For Windows Vista and 7 users, turning off UAC not only eliminates the annoying pop-ups but also speeds up the computer.
Just go into Control Panel – Security Center – USER ACCOUNTS – TURN USER ACCOUNT CONTROL OFF.
For those of you who don’t care about the graphical fancy pants that is Windows Aero, you can turn it off and thus save Windows from performing unnecessary gratuitous graphics when you’re simply navigating.
For Vista - right-click on the desktop – PERSONALIZE – click WINDOW AND APPEARANCE – OPEN CLASSIC APPEARANCE PROPERTIES FOR MORE COLOR OPTIONS – COLOR SCHEME – WINDOWS VISTA BASIC.
For Windows 7 – right-click on desktop – PERSONALIZE – Select Windows 7 Basic theme – OK.


9.) Remove unnecessary programs in Windows

If you buy a computer from an OEM such as Dell or HP, it’s most-likely filled with “bloatware”, the programs that are usually trial but are installed with the OEM’s copy of Windows. While these programs are harmless, they get annoying because they slow your computer down considerably. You can either manually uninstall each program from CONTROL PANEL – ADD/REMOVE PROGRAMS, or you can download and install PC Decrapifier. This program searches your computer, targets the programs that are considered bloatware such as “Auto Backup – Free Trial!”, “McAfee 90-day Trial”, and “eMusic” and un-installs them to not only free up hard drive space, but also increase performance.


10.) Defrag the right way!

Defragmenting your hard drive the proper way can speed up your PC in addition to organizing your files. Some programs like Puran Defrag not only defrags your hard drive(s), it also defrags your boot files so your Windows start-ups are quicker. In addition, there are comprehensive programs like Raxco Perfect Disk that optimize the placement of data for maximum performance depending on the settings you choose.
While there are many ways to speed up your computer, the goal for these 10 speed tips are simplicity and ease of use. Yes, you can tinker with your Windows Registry files but if you make a mistake, you can crash Windows just like that! The most important thing to keep in mind is remembering to perform the above cleaning tasks every now and then. (At least once a month) Just like proactively keeping your car in good running condition (ahem, Skyline GT-R!) with timely maintenance, running these applications from time to time keeps your computer running in peak performance. Regardless of whether you have a dual-core, triple-core or quad-core CPU computer, you did pay for your computer’s performance so it makes sense to able to utilize all of it.

Overclocking




Overclocking is an Art and if mastered an addiction
Overclocking today could be considered very common. PC retailers are beginning to give you the means to overclock your computer very easily, and some are even doing it for you. Now that overclocking is everywhere, I’m attempting to take it a step further and become a master overclocker. So, here’s what I’ve learned along the way…But before I begin here are some reasons you shouldn’t try overclocking your PC.

Reasons to not Overclock

  • Protection – Warranties are voided on almost all CPUs, and some motherboards as well.
  • Stress – More Stress on the CPU (and on all devices if you increase the FSB)
  • Heat – More Heat Generation from CPU (and RAM if you increase the FSB)
  • Sensitivity – The heat sensitivity of your system will be greatly affected. If you o/c in the winter and summer comes around, you might be forced to reduce your speeds because your system cannot work stably with the large change in ambient temperature.
  • Efficiency – Increasing your CPU speed with overclocking doesn’t increase its efficiency at processing data.
  • Hassle? – Some people get fed up with having to constantly adjust their system for stability. Other, however, find this the most intriguing and education part of overclocking, so it’s your call.
Now that you have mustered the guts to overclock your PC, here are some reasons why you should overclock.

Reasons for Overclocking

  • Speed – Your CPU will perform more operations per second (and your RAM if you increase the FSB)
  • Cash - Who needs to buy a “pricey” 1900+ when you can get a 1600+ for half the price and overclock it to the same speed?!
  • Troubleshooting – an Overclocker MUST know what is going on in their system, because if he doesn’t, he’ll have an unstable system. Being able to overclock successfully will educate a person on vast areas. Everything from CPU temperatures, to BIOS updates, to OS drivers, to motherboard jumpers. This knowledge is invaluable.

SAFETY PROCEDURES

Know what you have :
You should know everything about your system – motherboard, CPU, heatsink/fan, RAM, operating system, video card, and all add-on devices you have.
Understand what you are doing :
The term “Overclocking” is actually very general. There are several ways to overclock a CPU and other components. Please read MORE than what I am about to provide here, the intricacies of these components can span pages… While overclocking, you will change several or possibly ALL of the following:
  • Front Side Bus (FSB) – This is how fast your motherboard chipset communicates with your CPU, and is also one of the two factors that determine overall CPU speed in MHz.
  • CPU Clock Multiplier – This is a unit less value, who’s value increases or decreases in 0.5 increments (such as 10.0, 10.5, 11.0, etc) This value only affects the CPU, and is the other determining factor in overall CPU speed in MHz, when multiplied together with the FSB.
  • CPU Core Voltage (Vcore) – This is the amount of voltage your motherboard will stream to your CPU. An INCREASE in voltage will ensure that your CPU will cleanly pass data, and will prevent data corruption when your CPU is running at higher than stock speeds. An increase in Vcore will also increase your CPU’s core temperature. Find out what your specific CPUs voltage is, because not all CPUs use the same voltage. Look at AMD or Intel Corp.
  • RAM Voltage (Vio) – This is the amount of voltage your motherboard will stream to your RAM modules. Similar to Vcore, it ensures stability at higher speeds, although you will only need to increase this value at high FSB speeds, not high Clock Multiplier settings.
Once again, a reminder to please go out and find more resources on all and MORE data regarding what exactly happens when you “overclock”. That term is not specific in the least.
Don’t Rush :
The best thing you can do when overclocking is to not rush. Rushing will most likely lead to failure, which leads to aggravation. And there’s definitely a possibility of killing your CPU, motherboard, RAM, etc. if you rush.

TEMPS, TEMPS, TEMPS:

Any overclocker will know how well his heatsink removes heat from his CPU, and he will measure this using the temperature sensors that almost all motherboards include. Using either the BIOS or other software (such as Motherboard Monitor for Windows) will provide you with real time temperature values. Do some research to find out the acceptable temperature values for your CPU. I can tell you that all AMD Athlon and Duron CPUs should ABSOLUTELY and WITHOUT QUESTION be under 70C. If you are overclocking, you will require a much lower temperature. The reference point I usually recommend to overclockers is 60C at full load. Please note, that by “full load” I am suggesting a CPU intensive test. The best one I’ve seen is Sandra 2002′s Burn In Test. Run 50 passes of the two CPU benchmarks using Sandra’s Burn In function, then check your CPU temperature. If you are under 60C, you are safe. You can findSandra at www.download.com.
Check Everything:
My last safety suggestion would be to always take your time… make sure your heatsink is installed properly on your CPU and make sure you used a thin, even layer of thermal compound. Make sure your heatsink was perfectly clean before installation. Make sure all your fans in your case and on your heatsink work properly. Make sure your RAM and all PCI devices are snugly in your board. Make sure all cables on the back of your PC are snug.
Increasing the FSB will affect the CPU and also nearly all devices in your system. This is both good and bad, because in a stable system, while all devices will benefit from a slight boost, this also means all devices are stressed more than usual.
Increasing the CPU Clock Multiplier will only affect the CPU. What MOST overclockers do is increase the FSB and leave the clock multiplier alone. What the HARDCORE overclockers do is lower the multiplier first and then MAX OUT the FSB.
There is no reason you should ever LOWER the FSB from stock speeds, unless you’re in an emergency of some kind. It will NOT help in overclocking.

A WORD OF CAUTION ABOUT TEMPERATURES

If you computer ever runs too hot, stop overclocking, back off a bit on your FSB and voltage, and leave it there (make sure that it is stable using prime 95 and memtest) Make sure you do not run 65+C, or you run the risk of damaging something. Keeping it under 60C at full load is always good practice. In addition, I recommend that you get a good heatsink and fan before you even start to overclock. Keeping your CPU at acceptable temperatures is very important.
Your First Error
Once you get that dreaded error (and yes, your heart may sink, that’s ok), you need to increase voltage. Go by the smallest increment possible and run Prime 95 again. If you are able to pass this time, continue upping the FSB and voltage until you reach a 5% or so increase in voltage. If you cannot pass, then increase the voltage a little more (one more increment) and try again. Like I stated before, only increase your voltage by about 5%. Once you hit that voltage, stop. When you think you have found your best overclock, run Prime 95 for several hours (preferably overnight or for a day) to make sure that your computer is stable. If it returns an error, then you should back off your FSB by about 5MHz or so and try again. This process is very time consuming, but you want to ensure you are running a stable computer.
Are You Done?
Now what? Have you hit your maximum overclock? The answer is most likely, no. There are several little tweaks you can use to increase your overall clock speed. First, find out what is limiting your overclock. This can often be the CPU, motherboard, or RAM. To find out if it is your RAM, run memtest. If that returns no errors, then it is likely the CPU. If memtest does return errors, then it is likely either the motherboard or RAM. Try to increase the RAM voltage and see if you can get memtest to return no errors. If this does not help, then it could still be the RAM or motherboard. Sometimes, if your power supply is weak, that can actually limit your overclock. Your voltages should be within 5% of their nominal value. If you are overclocking, I would recommend a 400+ watt power supply from Antec, Enermax, or OCZ, but there are many brands out there and many threads here at guru on this topic, so search for one of those threads and see if you can’t find a power supply well suited or you. Generally, I would look for 25A+ on the 12V line (that’s 25 or more amps on the 12 volt line).
Are You Done Yet?
Still aren’t running stable? Try reducing your multiplier. Increasing your FSB is the most important factor in gaining real world performance. So, reducing the multiplier and increasing the FSB is a great way to get more performance. However, your motherboard or RAM will limit you here. For instance, you can run 10×220 to get 2.2GHz or 11×200 to get that. The 10×220 will run faster than 11×200 even though the processors run at the same frequency. Keep in mind that RAM or motherboard will be a limiting factor here, as long as you know that your CPU can run at whatever frequency you are running. Take for instance the 11×200. I know my computer can run that, but if it can’t run 10×220, I know either my RAM or my motherboard is holding me back. Try increasing your RAM voltage by few notches to see if you can achieve a stable overclock.
So, you’ve increased your RAM voltage and still can’t get it running stable. Now is it game over? No, not quite. You can try and loosen up your memory timings. You will see these values as something like 2-2-2-5 or 2-3-3-6 or 2.5-3-3-7 or 3-4-4-8, or something similar to that in your BIOS. Generally, I would leave these alone because increasing your timings can actually result in worse performance, even though you may be able to increase your FSB. As an example with my computer, running 200 MHz at 2-3-3-7 gave me 1423MB/s of throughput. Running 2.5-3-3-7 at 213 gave me 1486MB/s. As you can see, for 13 more MHz, I gained almost nothing (and you certainly won’t notice a performance gain from that). Running 2-3-3-11 at 200MHz gave me 1373MB/s. Finally, running 2.5-3-3-7 at 200MHz gives me 1398MB/s of throughput. So keep in mind that relaxing memory timings is not always the best idea. This option is more geared towards advanced and seasoned overclockers, so just leave this alone for now until you get more experience. The only reason I am sharing this is just to let you know it exists.
Ways to Spend Money to Get More Clocks
Now that you have overclocked, you are wondering if you can push it farther, yes? Well, the answer is, of course! However, that may require some money. Purchasing components that are known to overclock well is always helpful. So buying new RAM, a motherboard, or processor that is known to be able to achieve high speeds will likely allow you to overclock farther. Also, if you were limited by temperature (reaching 55 – 60C or so), you can invest in a new high performance heatsink or water cooling. This will cool your processor down more so you can increase your voltage. Also, something that is equally as important as your heatsink and fan is your case cooling. If you can, get more case fans to lower the temperature inside your case. This will result in your processor running cooler. This is very important. Like I said, the things mentioned in this paragraph will require you to spend money. If you are not that serious, then I would recommend you don’t really buy anything. However, if you enjoy this, and you want to get into it more, then by all means, help boost the global economy and buy more stuff.
