There are 2 large vertical lines that are distorted (colored) in the desktop at safe mode . The distortion is almost the same in uefi bios . When i normal boot the system throws bsods with messages like gpu driver failed to load or others gpu related . Sometimes starts and after windows logo displays black screen. . All that at idle and the card runs very cool (windforce gigabyte cooler)
Does your motherboard have integrated graphics?
If so, please try booting the system into Safe Mode without the graphics card and remove display drivers with DDU.
