Hi i am new here. Looked at the board previously but never signed up until now. I have been running my old Asus K7V33 motherboard and AMD Athlon XP 2500+ cpu for a while now in an old case i have lying around. It always used to run quite hot, the system wasn't overclocked and ran at 63c at idle (using Asus Probe) I purchased a new artic cooling silentium case and inserted all these components into it. The idle temp now is 71c with the side panel off! when running games such as battlefield 2, doom 3 etc.. the computer will switch off at random times and there will be nothing to make me assume that the cpu has overheated except when switching the computer back on the motherboard reports "the cpu has failed system check". If i restart the computer once more it will go back into windows but it may crash again. Any ideas why i have this problem? i am using the same components and the fan constantly runs at 7000+ RPM. I previously could run my cpu at 2Ghz without any problems and another 30mhz on my graphics card. I thought this case would make it cooler somehow with the sides on.
