PC won't boot.....when 4-pin CPU cord is attached. - Page 5

post #41 of 53
I seem to be having a similar problem.

I am RMAing for a new PSU ASAP. I doubt it's the motherboard or cpu in my case. It was just working yesterday!

This all happened when I put in my 2nd 580. The thing just wouldn't start. I'm thinking I just overloaded my PSU. One time the 12v was measured at 8v, so maybe it was defective and the 2nd 580 pushed it over the edge.

I know how you feel, I'm prepping for Skyrim...and I might not be able to play on launch!

Good luck to you, if I find a solution of my own I'll make sure to post it in here.

@ OP: PSU's are more likely to go bad first than a any other component in your system.

Sucks to hear. I RMA'd my PSU this morning to Amazon. Ordered a new one in the mean time. Hopefully we can both figure out what's up. Hope your 580's are alright.

How likely is a PSU going to kill a mobo or two though?

New PSU came in today. All the fans spun, no life on the mobo. The Gigabyte mobo has to be completely dead. I'm thinking the previous Corsair PSU I had fried both the Gigabyte and ASRock mobo.

At least I know this PSU works.....somewhat.

Eh, life happens. I live within 15 miles of a Microcenter and Amazon can ship items to me very quick. Just awaiting for Newegg to confirm my RMA'd board so I can get the cash back.

Nothing much I can do. It's pretty much all out of my hands now. Two dead mobos is a bit disappointing. I'll have to file an RMA for the gigabyte board this weekend.

I just hope to get everything up and running. Amazing what one bad PSU can do to all of your components. :/

Man I hope my PSU didn't fry my other components too. Especially my cards, that'll be the worst news. I tried powering that thing on over and over and I feel I may have ruined the rest.

What are the chances a PSU of this caliber could take out the rest of my computer? Aren't there built in safety precautions?

Your PSU was showing 8V on the 12V rail? Wow, yeah I'm not surprised that it wouldn't boot.

However, in your case I would imagine it's not booting simply because there isn't enough voltage, not because it's frying components.

Best of luck to you.
