System here is:
AS Rock x79 Extreme 9
i7 -3930k 3.20 GHz HexCore CPU
G.Skill DDR 3 - 1600 Mem. (32 Gig)
Seasonic Power Sup. 1000 Watt
Win 7 (64 bit) on a Samsung SSD 830 Series (128 Gig)
A longer time I had to work with an little older nvidia 620 and last friday i baught the EVGA 750 Ti FTW.
I removed all graficdrivers & folders before puttin the 750 on board.
After I put it in, I start the computer & after the Motherbord promt was shown, the comuter reboots it self, over and over again.
I boot a Linux Live DVD, to see if booting is still possible.
After this i did the repair funktion of Windows 7... found nothing.
After this I disabled the boot from CD / DVD and the computer starts into untouchable startpromt.
No F key ore Del was workin there.
Thougt the card was broken and changed it in the store I baught it before, to another one...
braught this home with the same result.
Last thing I've done was a complete reset of the Motherboard.
But still the same problem.
I tried all PCIe ports possible with the same result.
Win 7 stays untouchable.
So I put back the 620 and this is still workin normally.
Any helping ideas ? :(
