Need some help. I have an HP Omen 880-160se CTO which comes with a 750 W Platinum PSU and 2 PCI Express x16 physical slots (Gen 3.0), each slot with x8 bus lanes, I'm currently using a Nvidia GTX 1070 FE and it's all good, recently bought a gtx 1080 FE and when installed it's all black screen since I power up the PC, no bios just black! I tested the other pcie slot and the same happens, go back to the gtx 1070 and works great! I tried the gtx 1080 on an older PC with less powerful PSU and it works!! what is wrong with my PC? I tried once to uninstall with DDU but no luck! it's driving me crazy!
Can you help me?
