Computer won't POST need help!

by swimmrdave / October 22, 2007 11:36 AM PDT

We recently had a wind storm and the power went out while my comp was on. After recovering power 15 seconds later, I tried to power up the computer. The case lights and all fans came on, but the monitor received no signal input, and the computer failed to POST (no beeps at all). I figured that meant the CPU, mboard, or ram was bad. I was wanting to upgrade anyway, so i ordered a new cpu, ram, mboard, and vid card. However, the computer is still doing the same thing. I know it isn't the hard drive, because the computer would at least beep at me and give a warning message that something's wrong. So my question is, it it my PSU? I didn't think so at first because of the fact that the computer turns on and all lights and fans turn on (including the vid card and cpu fans). I would appreciate it if someone could help me as soon as possible because I have a limited time to return the new parts if they turn out to be defective.

The old computer:

AMD X2 3800
ASUS A8N-E motherboard
GeForce 7900 GTO
Antec True Power II 550 Watt PSU

The new:

AMD X2 6000
ASUS M2N32-SLI Deluxe Wireless Motherboard
GeForce 8800 GTS 640MB
Same PSU & HDD

Zap! Perhaps I'm wrong but

I wouldn't replace the CPU, Motherboard, Power Supply, or RAM if I were having problems with the Monitor and possibly the sound card. I'd replace the monitor and after that then maybe the sound card. Why do you think the power outage made any of your hardware burn out? I'd look elsewhere maybe a disk check for instance. More then likely this is a software problem. After some thorough checking here then move on to hardware. You will need a monitor of course to do anything. An extension cord with a fuse in it might be a good investment as well, about $6. Perhaps your not sharing something with us like, lighting struck your house or a telephone pole feel on it. If this is the case then perhaps a new computer is the answer

Monitor not the problem
by swimmrdave / October 22, 2007 1:58 PM PDT

The monitor isn't the problem, nor is software. The monitor works fine with other computers, and if it were a software problem the computer would post. And I don't mind the excuse to upgrade the comp anyway 'cause the wife couldn't argue. Of course, I didn't think that the PSU could be the problem originally, but I'm getting lots of feedback that says that's likely the case.
