Windows boot failure

[Nesagsar]

I installed a new fan, moved gpu from pcie2 to pcie3 slot, installed new bed, and changed out two ram chips. Not sure what did it. See image for error message.

I think it's the PCIe slot. Change it back and see if it works.

Moved GPU back to 2.0 slot and windows now boots properly. No idea why thàt failed. 

 

New HDD is showing in bios but is not showing in My Computer.

Fixed the problem with the drive, still looking for a reason on why my GTX 960 screws up in the PCIe-3.0 slot.

The motherboard probably is just messed up. Not all that uncommon.

What motherboard do you have? How old is it? What kind of power supply do you have? Could be that it needs a BIOS update, or it could be that it's not providing enough power to drive the card in 3.0 mode. Could also be one of those weird cases where certain PCI-E slots are run through a PCI-E switch and certain ones are direct-to-CPU. Or it could be buggy PCI-E ASPM / LSPM. If you have options for PCI-E power management in your BIOS, I'd suggest turning them off and seeing if that helps.

BIOSTAR H77MU3 motherboard

500 watt power supply

Almost all BIOS settings are locked.

According to BIOSTAR's spec sheet for that motherboard, the slot's PCI-E 3.0 function is only compatible with Core i5 and Core i7 3xxx CPU's, so a Core i3 or a 2xxx series i5/i7 won't work with it. It is strange that the slot won't downgrade to 2.0 gracefully, but since the motherboard firmware itself will report it at 3.0 and the CPU doesn't support it, the GPU is probably only listening to the firmware.

Speaking of which, it looks like only one BIOS update was ever released for that motherboard; If you haven't updated your BIOS before, it might be an idea to grab the updated revision just in case it fixes things for you.

I did update the BIOS soon after building the system so that apparently didn't have afix in it. Weird problem but thanks for figuring it out for me. I want to upgrade to an 1151 i5 processor anyway so it's also time for a new motherboard.
