yes the cpu fan is spinning, but very slow i can't see any display in the monitor, while the CPU fan is running very slow, so it is not possible to go into the BIOS setup . but one reason for the CPU to get heated up is "A Heavy Lightning was produced and hit the power supply.... at that time the system was switched off" i never switched on my PC after the lightning, two days later when i switched on the PC there is no display in the monitor, Both the Hard disk drive and CD-ROM drive blinks and stops..... CPU fan gets On and OFF, thats it , then i kept CPU fan separately aside (still connected to Motherboard) i removed the Processor and tried to switch on, the fan is rotating normal as usuall, when i put the processor into the slot, again then the fan runs very slow and the Processor gets heated UP. so do u any idea for it?
