Troubleshooting an old HP Pavilion a730n

post #1 of 5
Thread Starter 
So a few weeks ago my parents PC wouldn't turn on for them. I got a chance to take a look at it about a week ago and this is basically what I observed.

Power supply light on back was blinking in repetition when the power cord was connected to it. When I disconnected it, the blinking would gradually slow over time.

So I took the side panel off and looked around. I disconnected the PSU from everything and the first thing I realized was the light on the back of the PSU went solid green. It did this after I unplugged the 24-pin power from the motherboard. So I plugged it back in and it started blinking again.

The only thing I could visually find that might be wrong with it is a bad capacitor near the 24-pin connector. It wasn't bloated but it had corrosion on the top of it.

I also tested the PSU with a paperclip and the fan kicked on and it appeared to be fine. The light was solid green on the back.

The motherboard is an ASUS PTGD1-LA Rev. 1.06. I've been looking for one online but of course everything is overpriced and a rip off. The cheapest I might be able to get one for is $50 shipped. But I figured I'd make a topic here first and ask you guys what you think before I pulled the trigger.

If you need anymore info let me know. Thanks.

Couldn't you just buy a different motherboard?

Says that it's a LGA 775 mATX mobo, so it shouldn't be too hard to fine one. All you need to do is buy a new mobo and reinstall windows.

That's sort of what I WANT to avoid. If I can just get the same mobo and hotswap it then I can avoid reinstalling Windows on this 5+ year old prebuilt.

I would get a nice replacement motherboard.
Backup there user folders to a external, and reinstall windows.

I mean if I am going to replace a motherboard, taking some more time to have a fresh copy of windows on it only makes sense.
