Hey guys, long time since I had a hardware problem but here it is.

Monday I went to install Vista Business (from my school msdn). It would not detect the hard drive. It kept saying no hard drive found compatible or some BS. I googled and found it could be an issue with USB, but i didnt have any usb devices plugged in or set as a boot priority, basically I could not figure it out. It does let me look at it and format it and partition it fine.

I decided to disconnect everything non vital to install. So I opened up my case and disconnected all my hard drives besides the Raptor (my os drive).

Then I powered it up and here is where problems began. The PSU starts then quits 2 seconds later. Immedietly I thought the PSU fried. I ordered a new PSU with newegg that came today.

I bought a Corsair 750. The corsair powers up and stays up, my mobo powers up too. So it looks like this PSU is working. However I get no video and no post. The fan on the video card is running.

At this point im lost. I dont have any other computer to diagnose. I will try to get one next week to start testing but wanted to know if anyong had any thoughts.

As another note, I upgraded the BIOS on the motherboard hours before this started. If that matters. The computer was running just fine though.

My hardware:
Abit P35-E
PC Power and Cooling Turbo Cool 510 Express (3-4 yrs old)
2gb Crucial Ballistix
MSI 4850
74gig WD Raptor
Razer soundcard

At this point i think the mobo is dead, but im not sure. I really hope the video card is fine, its only a few months old.

I just can't believe what could have caused this, never had anything like this happen. I always buy quality hardware.

And on another note I started an RMA ticket with PC power and Cooling on monday and have yet to get a response (SIGH). These PSU's have a 5yr warranty.
 
Doubt it was your PSU, sounds like the BIOS upgrade F'd something up. Hard to say without another PC to test though :(
 
Well I keep thinking to myself there is a connection but I doubt it. I upgraded the bios like I always do, have done it 4 times now on this motherboard. I use a floppy drive. And the PC was working fine for hours until I decided to install vista.

The only thing i did was unplug my SATA hard drives from the mobo and unplugged their power to the power supply. PSU was off from the switch in the back at the time. Then after I hit power the psu fried.

My psu definetely is fried. I jumped the green and black pins and it does the same thing, comes on then shuts right off 2 seconds later.

However the Corsair is working fine. Powers up and stays up, mobo lights on, fans spinning, video card fans spinning. But I get no video so something else is borked.

If your saying the Bios upgrade was the root cause, it could be. I dont know.

Didn't know you did all of that. Maybe the PSU dying screwed something up on the board, hard to say though.
 
Problem solved. Forgot my old Crucial Ballistix needed 2.2v to boot up. I actually never had that issue with this motherboard before. But count on a new BIOS to screw things up. Looks like the new bios is more sensitive to that i suppse. Plugged in some other ram, changed voltage and i was back in business.

And still waiting on my PC Power and Cooling RMA 5 days and counting... i think im gonna have to call.
