Newly Built Computer Turning On and Off

post #1 of 13
Thread Starter 
I just helped my friend build a new build and we're trying to get it to work right now and it has trouble staying on. When we first booted it it turned on and off. We took out the memory and video card and reseated it and it turned it on to see it booting fine this time.

It got part way through the Windows installation and it happened again.

What could be causing this problem?

Pictures of the build? Like what parts exactly?

Also I think it might be the mobo shorting, becuase I was checking and my friend didn't screw all the screws in all the way.
We might try reseating everything.

Recommend disconnecting power from wall socket input A/C and reset CMOS.

Verify that your RAM is in the correct slots (Refer to MB Manual) and try using only one stick. Disconnect anything not required to boot. Extra HDs, etc.

Enter BIOS and check the default settings and temps. You may need to manually enter your RAM settings for instance. Set boot sequence, disable splash screen. Save and exit.

Are you sure the 430 Watt Power Supply can handle the 6850?

Try clearing CMOS.

I think this is the problem in the end. I don't think my friend seated the mobo correctly and it's causing power shortages...or something.

I've told him to take out the motherboard and re-seat it.

The sig rig is my rig, not my friends. And my 430W handles the 6850 all my case fans and a Corsair H80 water cooler perfectly fine.

Really?

Kidding aside, I'd imagine it could be a short, reseat mobo.

Alright well, my friend said he reseated the mobo perfectly and now it's kinda worse. The computer boots for not even a second and then turns off.

He said he's going to try getting a new PSU, he think the PSU might have crapped out.
