Answer 4

To speed up your computer and free up space and memory for free:

Go to the Start Menu> Run

Type in "appwiz.cpl"

Uninstall whatever you don't need.

Next, go to Start> Run and type in "msconfig".

Go to the Startup Tab and uncheck everything you don't want to startup. If you want, you can uncheck everything, and your anti-virus will still restart itself when you log on.

Now go to My Computer> Hard Drive> Documents and Settings> [USER NAME]> Local Settings> and delete everything inside the Temp Folder. (This is a hidden folder so you will need to have "show hidden files and folders" checked in Folder Options) All the files in this folder are just temporary files that your Internet stored for certain websites.

Next, you should install CCleaner, it will get rid of alot of temporary files on your computer. It also has a registry repair system, which is easily the best free one available on the Internet:

Another option is to try defragmenting your computer.

Go to the Start Menu and go to All Programs

Go to Accessories and System Tools.

Choose Disk Defragmenter and when it loads click defragment.

Next, go to Device Manger (Start> RightClick My Computer> Properties> Hardware Tab> Device Manager) and expand all listings. Now rightclick and update all drivers.

Another thing I would say is to compress your files if you already haven't.

Open My Computer and right click on your hard drive

Check the Compress Drive button and let it do it's thing.

Finally, make sure your Hard Drive doesn't have any bad sectors. Go to My Computer> Right Click Hard Drive> Properties> Tools Tab> Check Now> Check both boxes and Start. It will ask you to reboot, so reboot. This will clear out any bad sectors on your Hard Drive.

These are short-term solutions however. the easiest way is to just upgrade the RAM on your system, but at least the ways above are free.

Good Luck =]

Answer 7

Just follow arouge1786 advises.

I faced this problem also 3 months ago, Had tried to remove all unused programme. do virus and spy ware scan, disk scan. Upgrade ram All don't work.

Last I found that the Virus scan I uninstall is giving the problem because it do not remove all the files it installed and when the system get trigger to read some files that was remove during uninstall. It hangs.

Try the Ccleaner to clean up your reg. It help

Well.. When I install AVG ver 7. The speed was ok. But when it auto upgrade to version 8, my PC when dead slow some time. I uninstall it and the speed when back to normal now.

I suspect because more function ver8 is acting. It took up most of the system resources and it might keep scanning the file that your computer trying to read.

1 Viruses

2 Slowness/Lagg

3 Not Enough Memory

1. Viruses

If you just get a virus and it is noticeable try to remove it with your antivirus or antispyware.(If you don’t have one Download a free one off of Downlad.com such as programs like AVG ANTI-VIRUS, AD-ADWARE 2008, and etc.)If it does not work try to find any recent files that were downloaded anything suspicious . If all comes to fail you can use System Restore which will restore your computer to a previous day or week back when you didn’t have the virus. To get to system restore click START>ALL PROGRAMS>ACCESSORIES>SYSTEM TOOLS> SYSTEM RETORE.

2. Slowness/Lagg

Slowness or lagg is mostly caused from lack for RAM (Random Access Memory). Which basically means you have to many programs running at once. The normal amount of RAM that most computers have are about 256mb or 516mb which is not good. The better range of RAM memory that you should have is 1Gb to 4Gb as in 4Gb being the best. 1024mb = 1gb. There are many different types of ram to find out how much you have or what kind you have go on http://crucial.com/systemscanner/index.a... which is completely safe and will tell you possible updates or upgrades. If you do not want to spend money and just improve what you have you can remove programs temporarily from running off of the task manager by hitting ctrl , alt , delete then clicking the Processes Tab and removing known programs such as photo, printer, music, file sharing, and browsers. Try not to remove useful programs like explorer.exe and svchost.exe and files like that cause they can shut down your computer. If you remove needed program you can restart you computer and they will be back. To permanently remove programs from starting up when your computer starts up click START>RUN>msconfig>Startup tab. Try to remove files that are from your program files and not from common setup

Such as windows, rundll32 or regsvr. This will greatly speed up your computer depending on how many programs you have running.

3. Lack of Memory

To gain more memory There are a few things you can do. First you can click START> MY COMPUTER> THEN RIGHT CLICK LOCAL DRIVE (C) AND GO DOWN TO PROPERTIES>DISK CLEANUP. Then you can uninstall any unwanted games or programs by clicking Start>control Panel>Add or Remove Programs then click the program you want to remove. Next is to defrag you hard drive by clicking START>ALL PROGRAMS>ACCESSORIES>SYSTEM TOOLS> SYSTEM DEFRAGMENTATION which might take a long time. You should also delete any unwanted photos and songs which can take up a lot of memory. Finally always empty your recycle bin.
