Hello, i recently got a new GPU and i went from a NVIDIA GeForce 9600 GT to a NVIDIA Quadro K620. After getting the new GPU, i noticed that my pc takes longer to boot, my motherboard is Gigabyte H61M-S1. Another problem besides the longer booting is that i can't enter the BIOS. Everytime i restart i keep clicking the DEL key and it never takes me into BIOS, it just becomes a black screen and that's it. But if i don't press the DEL button, it just boots into Windows like usually, any suggestions?
