Well What do you know, this board is giving me problems yet again.
I left the house with my computer on and when I came back, the computer would wake up but the screen wouldn't. Eventually I just restarted the computer and it started beeping twice, and showing the code 5A.
It just beeps two times, then pauses, then beeps twice again, then pauses and then goes to the post code 00. I tried removing the GPU and the error persisted. Right now I just removed the CMOS battery. Is it time to replace the board?
