New Build Woes...

post #1 of 15
Thread Starter 
I was testing my new apartment pc computer build and was installing vista business on it. Everything was going good until it cut off. Now whenever I try to cut it on the red light indicating Over-Voltage, Under-voltage, over-temp, over-loading or short circuit lights up on the back of the power supply and the computer won't start.

I ended up taking my xfx 8800gt out and disconnecting the power to it and then everything else starts fine. I can even put the 8800gt in but not hook the 6pin power cord up to it and everything is fine except the graphics not working.

I have a Cooler-Master 750W Real Power Pro power supply as shown here:

http://www.newegg.com/product/produc...82E16817171024

It was working great for about ~30 minutes and now this? What's gone wrong?

Any help is appreciated. Thanks!

I surely hope not. I paid $100 for it and I doubt CM would replace it without me mailing mine back which isn't worth the wait.

Is there a way to find out besides buying a new one?

Have you tried using the other 6-pin PEG for the 8800 to see if it would start up? The other 6-pin is on a separate rail and there might something wrong with the OCP on that rail.

Yep I've tried them both to no avail.

They doesn't sound too good. Are you sure it's the PSU? If it works without the 8800gt plugged in, your gfx card may be bad and shorting out. Do you have any spare parts to test with? If you had a friend with a fairly power hungry gpu like yours to test with, that would be a good way to narrow it down to the PSU. If it is the PSU and you decide to RMA it, you may be able to talk CM into cross shipping a new one so you only have to wait a couple days.

I've got an 8600GTS from my current system I can test it with but I doubt it's anywhere near as power hungry as my 8800GT. I'll try putting the 8600GTS in my new build and the 8800GT in my current one and see if either one works.

Yeah the 8600 only needs like half the power the gt does, but it's better than nothing. It won't hurt to try it out, at least you can test the 8800gt in another system to make sure it is fine.

Well I tried what I said and the 8600GTS worked fine and the new computer started with it in it while the 8800GT didn't work in my current computer and the computer wouldn't do anything when I tried to start it. I guess my power supply is fine and my new XFX 8800GT is bad?

I'm not sure if I'm better off than I was before or not lol.

Well, you still have to get a replacement but at least you know for sure what was wrong. I'm glad you tried it without the 8800gt plugged in or we would have assumed it was the PSU and when you got your new PSU you would still have to mess with the video card.
