Hi, my computer specs are below. I stupidly updated my bios today and I couldn't get my pc to turn on let alone open the bios. So after a lot of fettling. (Dust removal, cable plugging in, resetting the bios and out etc etc) my pc finally turned on but only to a black screen. The bios will not open with Del or F2 but rather with f1, which the motherboard enables for when there is an issue. The only way i can enter windows is my forcing the bios to open it after pressing f1. (Windows will not start otherwise, only a black screen). How can i fix this? ie windows automatically start again and not have to press f1 to enter bios.
PS. The launch order is correct in the bios and i re-did the update using usb bios flash, to make sure it was correct
