Hi,
I'm having problems with my PC.
Until last month, everything worked normally. Then problems started, at several times after restarting Windows 8.1 the monitor began to show something like an interlaced mode, like every other vertical line is lost, even when entering the UEFI. I had to turn off the power from PC's power supply, and everything would return to normal. I tried replacing the video card, but the problem persists. I did not pay much attention because the problem was not frequent, I looked up the newer BIOS that would solve the problem.
Yesterday, as every day I tried to start PC and it stuck on the POST, I received only Q-Code AF and CPU_LED constantly illuminated.
I tried safety button repeatedly.
I tried clearing BIOS.
I tried removing battery from R5E.
I flashed the BIOS to version 1103 (and 1201). But there is still no solution.
I took off all components, check the socket, there were no bent pins. Re-signed all but still stuck on the POST with Q-Code AF.
