Hello all. Here's an odd one. Specs are 3570k in a Gigabyte z77-d3h, 16Gb RAM 4 sticks. Had a Radeon 7850 that went belly up after a couple years of loyal service. Switched over to integrated graphics to keep up and running. Recently got loaned a GT 730 until I can get a 1060 (machine is used for media storage and video editing, so CUDA / OpenCL acceleration is key).
Whenever I pop the 730 into the appropriate PCIe slot, the system will not boot. It either gets stuck in an endless boot cycle, or just hangs and will not boot - interestingly, when that happens, the MB screen says "Ultra Durable" in blue instead of of its normal red. When I remove the 730, on boot (after clearing CMOS) the board says the bios was corrupted and is being restored from the backup (an using F16 BIOS). Things I have tried prior to installing the GT 730:
1). Changing Initial Graphics from IGP to PEG
2) Disabling IGP
3) Setting boot ROM to legacy devices only.
What am I missing?
