what everyone said about the virus scans, and anti spyware and memory are all great advice.

Memory is cheap, better to have tons of it than not enough. you'd be surprised att he difference it will make in the computer.

On a side note, I have been messing around with other operating systems.

Ubuntu linux is now on my computer dual booting with xp, but I also have MAC OSX running on my PC Natively and it too is bootable fromt he windows startup menu.

I can choose xp, ubuntu, or Mac os.

The Mac osx is not 100% as it does not support all my hardware, but it runs pretty good and I did it just because I can. It is Mac OSX86, and it was designed to run on pc based hardware. it is still in development, because soon apple will be switching to intel processors.

All I can say is, I havent had a virus, I keep my antivirus updated and always running properly, and I use Ms antispyware, spybot and adaware all the time. Never had even a hint of a problem with anything.
