It started happening yesterday and the only thing I can remember that seems related is that the computer fell asleep and I've read that the P8P67 has problems with sleep mode.
The problem is that I get a completely black screen during the entire boot process. I can boot just fine, I can get into Windows7 just fine, I can use the computer just fine and it's perfectly stable. But I don't see the ASUS logo at the beginning of the boot nor the Marvell Controller screen that says it's reading my 6Gb/s SATA HDD (it reads just fine in Win7). I tried spamming the del key during the black screen boot process and it goes into UEFI just fine too. There seems to be no other problem, other than not being able to see anything until the "Starting Windows" part. Did anyone have the same problem? How do I go about fixing this?
