secure boot does seem to be the culprit, it should be compatible with your motherboard, any motherboard with a pcie slot should work with any gfx card!
Forgot to mention, the fan isn't spinning when it's plugged in either. Not sure what the case is there.
Yes you turn it off. its a option in the bios. You will need to disable it while the graphics card is unplugged and with onboard enabled.
so secure boot is now disabled? if your 545 can be powered by your psu the 750ti can, it uses half the power!
It's windows 7, in the BIOS I can't find secure boot. The BIOS on HP computers seems terrible as well.
EDIT: could it be compatibility with my screen. Silly question, but I just want to explore every possibility.
if you enable uefi and enter the uefi bios, can u see secure boot then? it seems secure boot is a uefi thing. Every card is compatible with every screen, unless you have like a 4k screen! I think the error your getting in device manager just means it cant access the card when your integrated gfx are plugged in.
but you can boot with integrated gfx? re enable uefi from bios same way you disabled it, enter uefi bios, disable secure boot, reboot with new card. i know uefi is a win 8 thing primarily but im sure people were using uefi before win8 was released so u must be able to access it.
