power supply dead;cpu fan dead,mobo?
I'm working on a 10-yr old HP pavillion pc. The pc would not turn on at all, monitor displays 'no signal'. the pc lights flicker. I had an older atx power supply and tried that- it worked. so I know that the old power supply was bad. the case was VERY dirty. almost all the vent holes were clogged. even after I tried my 'new' power supply, the cpu fan does not come on and I still get 'no signal' on monitor (the hard drive/cdrom drive DO come on). I'm thinking the power supply blew, taking the mobo with it. I don't want to spend alot of time on this, but can anyone offer any thoughts on this? thanks.

A 10 year old system that you don't want to spend a lot of time on. What can I say?

well, I'm sure not going to go out and buy another mobo for this beast. I guess I'd like to know whether my idea as to a toasted mobo makes sense. Or is there a way to rule it out? The only thing keeping from trashing it right now, is my sister didn't do alot of backing up and we'd loose alot of data.

You seem to be comfortable taking apart a computer, so why don't you just take the hard drive out and put it in a working computer and copy the files you need? Sure would save the headache of troubleshooting a 10 year old HP. That's assuming the hard drive isn't dead.

As for your theory, sure it makes sense. Just a few weeks ago I had a customer who had a faulty PS take out his mobo, RAM, and PCI cards. It even went so far as to fry the two hard drives. If there is a path for electricity to take it will find it.
