Question Pc boot loops if theres a gpu installed

[Deviantchuckler]

Hi ive had the pc for a while and the last thing i changed was the gpu to a geforce gtx 1070ti about a year or so a go. Today when i tried to turn the pc on it got caught in a boot loop. Ive tried resetting the bios, resetting windows and the only thing that works is to have no gpu installed. Without one it boots normally and ive tried two of my old gpus aswell. Can anyone think of the reason?

Does your motherboard have TPU and EPU switches? Make sure they are turned off and attempt a boot.

The closest i see to that is intel(r) turbo boost technology.

Motherboard - gigabyte z77-d3h
Cpu - intel(r) core(tm) i5-3570k cpu @ 3.40ghz

After booting it sometimes says bios is corrupted and tries to fix it

Solved ? Changed pci to legacy and display prio to pci and it has booted with gpu installed
