I have an ASUS P4S533-VM Board. I originally had a Celeron Socket 478 1.7GHZ Cpu on the board. i wanted to change and i put in a pentium 4 3.0GHZ Socket 478. When i started up pc, all that went was the cpu fan for a second and stops. The green led on the mobo stays on all time when power is in.
I tried putting the old celeron back into no avail. Removed all peripherals except ram, still no good. Tried different PSU. Cleared CMOS, changed Ram configuration, kept ram out, done all, but still no booting sequence at all.
Can anyone help me please?

Re: CPu fan turns for 1 second and then stops.
If all was working fine before, then, you have either not connected the cpu power cable, as is sometimes required other than being powered by the processor socket, or your power supply unit is not pentium 4 compatable and is unable to power the processor.

You do not use a jumper to run the CPU fan. There will be a small 3 or 4 pin plug near the CPU mount and you can plug the wire from the fan into that plug only. If the one on the motherboard has 3 pins and your plug has 4, you can use it anyway; just be sure the slot on the back of the plug matches the side of the one on the board.
