Power supply problems

[Kevindv10]

A user went to power on her machine and gave it a shock from the static in the building. Since then, the machine will start up for a couple seconds and then just power down again. I've switched power supplies and had the same result. Anyone have any ideas how to fix this?

Cheers.

You probably zapped something on the MB, though it's difficult to say without seeing the machine and tinkering with it.

So what would I look for? What kind of tests can I do? Obviously I donj't want to write the machine off unless I've exhausted all the possibilities.

Thanks for your response.

Well, the next test involves removing everything but the video board, and trying to see if you can get the system to at least get to the POST in the BIOS. If that fails, I'd replace the video card and try it again. Finally, if that fails, it would appear that the MB is the only component not replaced, so it's probably time for a new one.

You might also try replacing the RAM in the PC.
Make sure the CPU's heatsink fan is working.
