Hello people, A few weeks ago I had an overheating problem with CPU(Pentium D 3.4 Ghz). The temp was like 110C, working a few minutes and than restarting. I knew its CPU problem so I changed it, bought a new Intel Core 2 Duo E8400. Now this one is working good (temp. 35-42C) but the problem is that after around 8 hours of working it keeps restarting again and the temps are still cool (35-42C). I made some tests, formated disk and installed a new copy of windows, switched the RAMs in different slots, replaced with different one, stoped the "Automatically Restart" option of windows and still the same problem. Does anyone know how to fix this ?
