This has been happening for awhile and recently it just got worse when we would play games for a long time the computer would just restart. One time we got a BSOD which said I ran out of physical memory it also listed some file names but I forgot to write it all down.

We cleaned the dust out of the video cards fan but it still causes the system to restart and I fear that if it continues I will eventually need to reinstall windows xp.

Also no virus's or trojan horses were found on this computer.
