What the?

Hi,

I’m running an AMD2200+, with 1GB RAM, 128MB GeForce Ti4200 and a 40GB 5200RPM, DSL Internet.

Whilst running Windows XP Pro, the computer Freezes. I;ve tried running the PC on two different DIMM’s ie removing 512MB and swapping, doesn’t work, keeps freezing. I’m at my wits end. What is wrong with my baby????
