GTX 670 Not Detected by Motherboard

Alright. Flashed with the most recent bios. Graphic Card is still not being detected.

Sadly, I do not have another mobo to plug in the graphic card.

Does the setting in BIOS still revert from PCI-E to AUTO?

When you update BIOS you should probably "Load Optimized Defaults" and then go through and check everything.

Is the PCIE slot disabled for some reason? Does the video card work if you put it in a different PCIE slot?

Next step would be to determine 100% whether the video card or motherboard is broken. So you would need any other PCIE video card to test... can you borrow one from family/friend/collegaue/work? Or buy the cheapest PCIE video card you can find.
And ideally also test whether your 670 is detected in any other system (family/friend/colleague/work).

If not possible, then you may have to buy a new motherboard and/or video card - probably both to be safe :\

Yeah the setting still reverts.

I did the optimized defaults thing. The only real setting that I have to change is setting my hard drive to IDE as opposed to AHCI (does not let system boot).

So my motherboard has two PCIE. The video card did work the first time I changed it. The secondary slot, however, reduces performance so I reverted back to original. After the reversion the card wasn't detected and so I put it back in the secondary slot and then it was again not detected (this happened a couple of days ago).

At the moment it is being detected and running fully well (played black flags on highest settings - I am afraid to shutdown my computer). I think that something about the system shut down causes the graphic card thing to reset. I am not an engineer but does the graphic card have load up capacitors/battery, which it uses to start up? The graphic card is not detected for 48-72 hours after a shutdown, after which it suddenly reappears. Perhaps the battery/capacitor need to build the charge or something? That is my theory at least... not sure.

Of course, if the capacitors had gone completely bad then the card would not function perfectly well once detected (which it does). Its just that it is not detected for sometime after a reboot and randomly gets detected again.
