Hello everyone I am having problem with my pc heating up too fast.I cleaned it today and now with everything connected properly CPU temp increases 1C every second even at BIOS screen no windows.It reaches 90c and turns off.I removed heat sink and CPU is not even warm. Its an old intel D945gccr mobo and P4 3Ghz . Thanks in advance for any help and sorry for bad English.
Wrong !!!! Without a heatsink and fan your computer would either burn out the cpu or melt down the motherboard...Always try to keep your CPU below 50 degrees at least..
