My computer keeps freezing after only 3 or 4 minutes. It’s a mesh 3.2 processor, 2 GB ram, windows XP, SP3, GE-force 6800GT graphics. I have checked all the connection and inside the tower. No programs have been downloaded. It’s been getting worse lately and practically unusable now. This post has taken 4 attempts to post it. Any ideas what could be causing it?
