Thank you very much.
I am getting the arctic silver 5.
A fool's question: If the problem was motherboard/power supply unit, my Dim 8400 would not be working right now, no?
I am having a problem with my dell pentium 4.
There was a storm this morning in my area. When i woke up i saw that my cpu was off, which is not expected because i have a brand new Battery Backup UPS.
First time i ever encountered this problem. I took out all the parts, cards, RAM & cables, and tried but still the cpu MOBO jus lights up, no fan works.
I manually powered the PSU by bridging the wires, and the PSU worked fine.
Then i removed my CMOS battery and there.... i got the CPU to power on but there is no display on the monitor.....no lights at the front light up.....no diagnostics lights work.......
I even tried removing the P4 connector that connects the power for the MOBO, but still......
when i reconnect the CMOS battery the system just remains dead....meaning that the MOBO jus lights up....no fan power or anything......
can anyone help me.....
thanks in advance
Connect the power supply cord directly into a working outlet.
If you are comfortable working around computers, you could try the following:
Note: The only 100% method of testing a PSU, is to install a know working power supply.
Unplug the cord from the power supply, hold the power button in for about 15/20 seconds, open the case, unplug the 20-pin power connector from the motherboard and jump the Green wire to one of the Black wires, reconnect the power cord and power the system on, if power supply's fan and the hard drive run, then the PSU should be good.
Note: Do not remove any wires from the plug, use a small piece of wire or a paper clip as a jumper.
Power supply checks out and the system still does not work, again remove the power cord, hold the power button in for several seconds to discharge the residue power, reconnect the 20-pin connector to the motherboard.
Remove all the PCI cards, the video card [if applicable], memory, all peripherals, disconnect the data and power cables to all the drives, check that the front panel cable is connected to motherboard, with nothing else connected to the system, reconnect the power cable and power the system on.
If you do not get any beep codes and/or there is no change in the diagnostic lights, it would appear that the motherboard and/or the processor has died.
