Hello everyone,
i got serious problems with my HD 7970 since last week and did not manage to solve it by myself. My screen has red stripes coming up in BIOS and Windows load screen, but black screen before Logon showing up.
GPU: AMD Radeon HD 7970
CPU: Intel Core i7 2600K
Mainboard: Gigabyte P67A-UD5-B3 F8
I had the same failure about half a year ago directly after a windows update. I solved it by deinstalling the latest windows update and reinstalling graphic driver in windows safe mode, as far as i remember.
This time, even windows safe mode did not work. So i reinstalled windows completely, but without success. It was quite hard to get the installation till end, because the black screen always stopped the installation.
After various tries, including CMOS restore, i can't even access BIOS. I just got Black Screen from the beginning.
Fun Fact: I switched the Card on the Mainboard: in PCI x8 Slot i see BIOS and Safe Mode, but PCI x16 Slot is not working at all (Mainboard PCI-Problem LED is on).
Can this problems really be initiated by an "simple" driver or windows update?
Or has my card finally given up...
