Motherboard has power but PC won't power on at all?
Hey guys, I just recently built a rig and thus began my first steps into overclocking (i never overclocked my previous rig).
So about 2 hours ago, I was benchmarking grand theft auto IV when my GPU suddenly ramped up to max fan speed and I lost picture on the screen. My gpu is an EVGA Geforce GTX 670 FTW.
So I rebooted the pc and it gave me the message as follows: "Please power down and connect PCI-E cables into this card" (or something like that). So I checked to see if there were any loose cables and there weren't! I even went as far as using some spare molex to PCI-E adaptors and still the message popped up. I tried a different PCI slot and still the message popped up.
Here's where it gets interesting:
So I decided to plug it back into it's original PCI slot and give it another shot. Plugged everything back in and made sure everything was snug. I flipped the switch on my PSU from "0" to "1" and the little LED light showing there was power to the board lit up like normal.
I press the power button.
Nothing! The case fans power up for less than half a second then nothing. My CPU fans don't even move at all! Loose cable maybe? I checked and there wasn't anything loose!
So I contact a friend of mine (who referred me here) and went though some test to see if it was something minor. I tested the power supply using the paperclip trick and the fan came on. I took out the GPU and plugged my monitor into the iGPU. Same issue. So now i'm stumped and have no idea what to try next.
I also checked for shorts (a loose screw maybe) and didn't see anything.
I tried clearing the CMOS and switching to the secondary BIOS but i recieved the same issue.
So here I am..I'm stumped and I really would marry the person who could help me with finding a solution to my gremlin!
My PC specs:
Intel Core i5 3570k (Costa Rica Batch)
Noctua NH-D14 CPU Cooler
Gigabyte GAZ77X-UD3H motherboard
EVGA Geforce GTX 670 FTW
8GB G Skill Ripjaws DDR3
Corsair Nova SATA II SSD
Ultra X4 600W Power Supply
Just as a reminder from the TL;DR story: My motherboard receives power but when I press the power button (including the one on the motherboard itself), the fans spool up for less than half a second then stop. I'm not sure if that would count as a "It won't POST" situation or not.
Right now, I'm testing the PC components on my old rig to see if they work on that one.
