Help! VGA no signal

post #1 of 6
Thread Starter 
Hello,

I recently got all the parts for a new PC, it is as follows:

Intel i5 3570K
ASrock Extreme4 Z77
Sapphire 7870 Ghz OC edition
Kingston HyperX 8GB 2x4 Kit
Seagate Barracuda 1TB
Lite-On 24x DVD Drive
Corsair TX-750 V2
Asus VS248H


Now, everytime I boot up the PC, I get 'VGA No Signal'
I've tried changing the monitor, Changing the display cables (VGA (With DVI to VGA converter), DVI), Changing the GPU, Changing the PCI-E slots, The PCI-E connectors, still nothing...
I took my GPU down to my local PC store They hooked it all up and it worked fine... So I took it home and hooked it up again, VGA NO SIGNAL..... mad.gif
The GPU fans are working so there is power going to the board.

I've double checked all connection and it is all connected from what I understand, I can't think of anything else!

That's pretty strange that the computer shop was able to get video, so I'm not sure if this will work but you've tried everything I can think of. (other monitors/cables etc...)

I recently built my computer on the same motherboard and couldn't get video without using the onboard VGA. I had to reset CMOS with the graphics card already in the PCI slot. For some reason it wouldn't detect the card because it would look for the onboard one only, then stop.

Why do you still use VGA in 2012?
