The motherboard is an ASUS P45800-MX using Windows XP SP3, about 1.5GB RAM. Has AGP video card, 1 HD (IDE), CD/DVD drive and floppy drive.

Six moths ago installed a new power supply unit (PSU).

Problem is the computer will not turn on. When I press the start button, computer will not boot. I notice that the green pilot light on the motherboard does not light on. When I turn the main power supply off and then turn it back on the PSU, this pilot light comes on then fades off.

Any ideas/suggestions.

check for any swollen or leaking capacitors

it may be shorting somewhere

Please mark as solved.

Played with the power leads to the motherboard and power now going to the MB and it boots up. It may be a warning that the MB is about to bow out, so I have done a backup of recent documents.

Re: [SOLVED] Computer not starting/booting

glad you have it sorted

one of the connecting contacts may have been dirty or had some corrosion
