I scan for viruses daily, I defrag once a week, scan disk a few times a month and run spybot sd regularly. My computer is not overheating.
Intel Core2 duo 3.0 GHz
ATI RADEON 4850
500GB 7200RPM hard drive
Let me know if you need to see a DXDiag or if there's an errorlog file i can post.
Thanks in advance.
