As I believe this issue is either connected to my Gigabyte X79-UD3 motherboard or my brand new Gigabyte GTX 780 Ti Windforce graphics card, I thought I would post here. Forgive me if this is the wrong section.
My system is home built
Win7 X64
Intel i7 3930k Hex core stock clock
Corsair H100 Hydro
Corsair Dominator 16Gb RAM
Gigabyte X79-UD3 motherboard
Gigabyte GTX780 T1 Windforce GPU
128Gb SSD root drive
6Tb HDD storage
Enermax Galaxy 850w PSU
3x Dell U2413 24" WS monitors
Logitech G19 keyboard
Logitech G700s mouse
The Gigabyte Graphics card is brand new and freshly installed today. I took every precaution to make sure it was installed correctly and indeed it seems to be so as I managed ot post a very healthy PCMark rating with it without issue.
However, when I boot the computer, it displays the American Megatrends logo on my central monitor. Nothing else appears on the screen (I disabled the splash screen ages ago anyway). It stays like this for maybe 90 seconds, then turns the main monitor off and displays the Starting Windows logo on my left monitor. Then it turns the central monitor on, then off then on again and displays the blue Win7 splash screen on the central monitor before booting into windows. At that point, my USB mouse does not work and I have to remove and replace the cable before the computer will acknowledge its existence.
I've checked in Device Manager and there are no Exclamation Marks or errors in drivers. I've checked all drivers and they appear to be the latest ones for each device (GPU, mouse, keyboard etc).
I've tried booting without keyboard and mouse attached and the same hang appears at the start. I've also tried different USB sockets (there are six on the back of the mobo) to no avail.
Could this be a power draw issue? I know my 850w PSU should be up to this but I had to use one of the supplied twin molex to 8pin adapters that came with the graphics card as I didn't have another 4pin PCIE cable. I've ordered a 6pin to 8pin PCIE cable and will try that tomorrow.
The one thing is that I can't get into BIOS at all. Literally there is nothing else on the screen when the American Megatrends logo appears and hangs. I've tried hitting DEL to get into the BIOS and even F8 to select boot method and neither of them work.
Any thoughts gratefully received please.
