Cannot boot my computer with a motherboard-graphics card combo

post #1 of 3
Thread Starter 
I have recently built a desktop computer. It was working fine until suddenly it stopped booting. The configuration is,
Intel Core i5 3570 3.4GHz (3.8GHz)
Gigabyte Intel Z77 GA-Z77X-UD5H-WB WiFi (BIOS version F14)
G.SKILL Ripjaws X 2*8GB DDR3 1600 (PC3 12800)
ASUS GeForce GTX 660Ti 2GB GDDR5 DirectCU2
OCZ Technology Vertex 4 128GB
Corsair HX750 750w

The motherboard has debug led, it reads A9 (BIOS Setup is started) when the booting gets stuck. The sequence can be found here, http://www.youtube.com/watch?v=wiANXvURIZo
The full list of debug led codes can be found here, hhttp://download.gigabyte.ru/manual/mb_manual_ga-z77x-ud5h_e.pdf

After doing the usual component diagnostics, I have been able to boot by swapping the graphics card with a XFX Geforce 9600GSO.

I knowledge says the problem is with the graphics card. I have RMA'd the card and ASUS sent me new card and I have been unable to boot with the new card either. Can somebody please confirm or point me to the actual problem if not graphics card? Also what may have caused the failure (if my fault)? I want to prevent future mishaps.

It could be that the 2nd card is DOA, probably unlikely or just bad luck, or that your mobo; the PCI slot is defective and can't keep the juice flowing for a card more demanding then a 9600. I'd try to borrow a beefy card from a friend (make sure it's plugged correctly to the PSU) to see if that works, and if not then the mobo is probably the culprit.
