I couldn?t find much on the motherboard either. Over the years I have only seen a handful of boards with fuses so I doubt you have on your board. -Double check the new power supply and ensure it is designed for your motherboard. -Double check the power supply connections to the motherboard, the connectors should mate up exactly to the motherboard. -If you did remove anything double check for shorts, grounding and so on. Any of those can cause the same symptoms. -Test the case power switch, it could be bad. -Some power supplies have on/off rocker switches on them (in the rear by the A/C power socket), make sure it?s on. -Most power supplies have a 115/225 volt switch in the rear by the A/C power socket; make sure it is set to whatever is appropriate for your country. I assume you use 115V like we do down here. -Make sure the A/C power cord is working. -Test the power supply in another computer or if not available you can generally pickup an inexpensive tester for $10 to $15 at a computer store that sells parts. -If you get this far and still have no solution then my guess would be the old power supply had a power surge on its way out and damaged something major on the motherboard. You can look on the motherboard for obvious signs of damage; however, unless you know what you are doing I don?t recommend the typical user try to perform repairs of this sort. Let us know how things go or if we can help further.

Dvd player will not come on. problem seems to have started after a brown out


It is very possible the internal fuse burnt out. If not the fuse, then possibly the power supply burnt out. You can test the power supply with a voltmeter.

Does it have a fuse we got hit by lighting and now the Pc wont power up


To fix the problem, you need to disassemble the power supply, replace the burnt out fuse, & also check the bridge rectifier section for burnt out rectifying diodes (these usually get burnt out if the high current gets the chance to leak past the fuse, which could sometimes happen). If you find burnt out rectifying diodes, you will need to replace them as well, as they could burn out the fuse again when you try to use the power supply while they are still there.

Mobo does not power up Dead cpu dead mobo?


A dead CPU will not hinder a board from powering up. The board is unlikely to POST. However, you should heard attempts at powering up and immediate shutdown. Or, you will see the PSU comes on but system not boot.

No mobo, but, CPU.

If no failed attempts at boot, no indicator lights, then you have either a failed power supply or DEAD motherboard.

Good luck

Monitor fuse keeps blowing


There is definately a shorted component that causes the fuse to blow. Nomaly the ceremic capacitors are the cause of the problem. Check to see if there is visiual dark or burnt ceremic caps with label sameting like this "SCK 083" near the fuse area and change it. Hope it helps,cheers.

Foxconn 661M03C-6L MB and Pentium P4 1.8GHz Processor


I suspect the issue is that the 1.8 uses a 400Mhz system bus speed, and the mobo likely only supports 533 and 800.

P4M80-M4 not powering up


You may have the power and reset connectors on the right terminals, but they may need turning around, normal rule of thumb is if the markings on the connectors are on the outside, then turn them to face inwards.
