OT: Speeding up a slow computer

[Solymr]

Trust me, it happens. As you use the OS more it accumulates more and more "rubbish".

I'm building a new computer and while I'm waiting for the RAM to come in, I've preinstalled XP onto a new hard drive with this computer. Now, the copy of XP on one of the drives on here that I boot from has been installed for a year and a half now and pretty much runs poorly. The fresh XP install on the new hard drive runs like a dream, and ran Oblivion really sweet on this computer, which normally would be a bit jumpy.
