Have you got any idea, how to improve the computer speed.?

I have a four year old Pc

Operating system: Windows XP home

Processor: Pentium4, 2.4 Ghz

Memory: 512MB

Hard disk: 65% if free at the moment

None of the program is to set to run at start-up (Except Northern antivirus)

But it鈥檚 still running very slowly. I have update Windows xp and antivirus.

I also done the full virus scan as well. There is no virus.

Make sure you're "ONLY" running Norton. It sounds like you probably are so this is more of a PA statement. Having more than 1 AV program will make a computer nearly useless as they take up all your resources trying to decide which one is protecting the system and which is the potential virus.

Large backgound pics and animated pointers take up a lot of resources.

Setting your virtual memory to auto will likely help. Suposedly there's ways to make the computer use ram before vram, but every time I've come upon a slow system it always seems to have been set rather than letting the system decide what it needs. Switching it to auto has always helped. FYI, right click 'my computer', select properties, go to advanced, performance options.

The main culprit I suspect is services but it's hard to figure out which ones are good and which aren't. My advise would be to just whipe out the OS and start from scratch. It's the only way to make sure you get rid of all the junk.
