First of all, open the side and look at the heatsink/fan. Do you see a lot of dust on it? If so, clean it all out of course. If you don't feel like removing the heatsink to do this a can of air and some tweezers should suffice. If all is well there, download Prime95 at: ftp://www.mersenne.org/gimps/p95v2412.zip Once you uncompress and run Prime95.exe, click "Just stress testing", then click the options tab, click "torture test", select "in-place large FFTs". Let that run for at least an hour.. see if you get any errors. If you do, this means the CPU or ram could be overheated or are going bad. Another possible but remote cause is the power supply is giving out and dropping the voltage on the +5 rail, sagging it to near 4v will cause instabilities as you are describing. Also make a boot disk or CD with Memtest86+ v1.55, boot off of that and let it run until all of your memory is completely tested. If you get any errors you probably have bad ram, but an unstable CPU can also cause this.. so first make sure your voltages in the bios are normal (+3.3 around 3.3v, +5v close to 5v, etc) and your CPU is cooled sufficiently. If you still get errors then test your ram 1 stick at a time to isolate the bad one. Download Memtest86+ @ http://www.memtest.org/
