One day I booted up my computer to a blank screen. Went through the obvious troubleshooting. Checked monitor cables, checked monitor on another desktop, reseated graphics card, even tried graphics card in another computer and the card works fine. Tried another graphics card in the original computer, nothing. It wouldn't even post. So I figured the PCI-E slot was bad on my mobo. Ordered another mobo, after installation, the computer boots up fine, I get in to my desktop, and start installing all of my equipment to the new mobo. I install all the drivers and give it a reboot to let the drivers kick in. When it reboots, the same problem all over again. It wont even post. I can hear the HD and ram working...but no signal no matter what I do.
Ok, update. One of my monitor extension cables went bad, so I can get signal from my onboard card, but not my PCI-E card. I have tested the card in another computer and it works fine. It booted up once before with my current setup. The card requires 2 PCI-E power hookups. Is it possible that the power supply is bad and not giving it enough power? If this is true...what voltages are supposed to be going to it so I can test. All the LED's on the card are lit up.
Old mobo was Asus M2N-SLI Deluxe, new mobo is MSI 785GT-E63
