Power supply or motherboard issues?

post #1 of 6
Thread Starter 
Hey guys,

I'm currently at work (well, work experience ) and I'm working in the IT department of a company.

I was asked to try and fix a computer that they have been having problems with recently. It wouldn't boot up at all and when it did it wouldn't boot up to Windows. Well after fiddling around inside the case and securing connections etc, I got it to boot up.

Me and the other IT guy thought that this was either a motherboard, or a power supply issue.

The computer in question is a prebuilt one from Asus. I don't know the model but I know that it's a P4 Dual Core 3GHz with 1gb of GeIL PC3200 RAM. The motherboard is one of Asus's value ones with a VIA chipset. It's tiny, like a little L-shape motherboard with a PCI-card addon board which is a bit odd!

Anyway, I'm pretty much concluded that this is a power supply problem, so recommendations for a small power (200-300w with a decent 12v rail) supply for pretty cheap that will fit into a mATX case.

Actually I don't know if it's mATX.. this is the case:


Thanks in advance

I don't think a power supply would do that. You could always test that out by trying a different psu if you have one available.
Sounds like the mobo has seen its better days.

Swap out the PSU. If the problem is still there, it's not the PSU.

I suppose it could be either perhaps under load something is failing.

The computer is actually fine once it gets booted up. I think the problem is definitely the PSU because I went into BIOS and the 12v reading was 11.3v lol.

Try bringing your own PSU up there and see if it works.

And turn my beloved PC off?!

Nah the guy I'm working with says they're gonna order a new PSU anyway.

Hell, who knows, if it turns out the new PSU doesn't fix it maybe he'll let me have it.

All I need then is a cheap mobo with onboard video and I can have a folding rig lol.
