Mobo help...

I really need some help on this because it's really pissing me off a lot.

I was fixing a friend's computer. I noticed that the power supply wasn't working. It was 420W. I replaced the power supply with one that was 150W, turned it on. It booted on perfectly. I'm thinking "yeah, I fixed it." I gave it back to him.



The next 3 days he calls me telling me that the computer doesn't boot. He told me that he never messed with the insides of the computer once he got it neither he spilled any water hazards in it. So he gives it back to me. I'm thinking "Was it the power supply?" So I buy a new one that has 450W. I connected it, and it still wasn't working.

"Could it be the Video Card?" I was lucky that he had an AGP slot. I replaced it with a new video card, and it still didn't boot.

"It should be the hard drive." It couldn't be the hard drive cause when the BIOS loads, it would've told me it was faulty. I did it anyway, no response.

I then remembered that I removed and put back the power switch cord, but it couldn't be that, right? So I declared that the Mobo was fried.

I put it in a new computer. All I did was switch the hard drive. I put better RAM, an Intel Processor since it was an Intel Mobo (the old one was AMD), the Ethernet Card and a new DVD drive. I had to take off the Power Switch cord so I could do all that. I turned it on, same thing.

I swear to god I was about to kill myself when this happened. Can someone tell me what is it?

NOTE: The computer turns on, but doesn't boot. Monitor doesn't turn on. HDD Led stays on, never blinks.

do you have the front pannel connected properly and the os correctly installed, windows usually has a hissey fit if you chang too many things
 
If it has XP on it, you have changed so much it might not boot into windows! But are you getting a boot screen? If not is there any beeps
 
Okay, just for no more questions:

The Fans work
The CD Drives open
All I get is a red HDD light
The HDD sounds like it's operating
The Processor Fan Works

And just so you know which Mobo it is, it's an ABIT-AT7-MAX2
 
well it obviously isn't the hard drive because you said that works in a different computer so that variable is eliminated, if it was a video card the computer would still boot you just wouldn't be able to see anything. So that leaves us where we are now, if you aren't getting any power to anything try a different power supply. If it will turn on but won't do anything it might be the mother board is junk. It all depends on how far it will go, if it will actually go through the memory count and bios detection crap then the board probably is still ok, but if when you turn it on you hear stuff power on but nothing happens (screen stays blank) then i would have to say you have a bad motherboard.
 
Ok. Get the new PSU, a working VGA card, one stick of good RAM, the processor and the fan. Don't even put it in the case. Power it up and turn it on. See what happens. If that works, you can begin to isolate the problem. There is a reason why I say don't put it in the case.
