So I'm helping a friend build their first computer. They had 2 old ASRock Z87 Pro3 motherboards lying around (in box) that an old boyfriend had bought and never used. We built around that board with a 4690k and an R9 390. When powered on, the build would turn on, reset a couple seconds later, then come back and stay on with no video output. We figured out that the included BIOS was too outdated for Haswell Refresh procs, so we ordered a new BIOS on Ebay which came flashed with version 2.9, the latest version and one that officially supports Haswell-R.

We put the new BIOS in today, and this time, instead of restarting, the PC came on and stayed on, so I'm confident there was at least some positive progress. However, we still got no video out from the GPU, so I removed it and we also got no video out of the iGPU. We've tried DVI on both the GPU and mobo, as well as VGA from the mobo. We've tried only one stick of RAM in either channel and a different stick of RAM out of my build. We actually ended up with two BIOS chips due to a shipping mistake and tried both with the same results. I've cleared CMOS several times to no avail. I'm out of ideas at this point.

So anyway, we've been at this for a while, and the elephant in the room is that we have a whole nother motherboard which we could try instead. Obviously that's not a terribly appealing undertaking, but it's an option. So, my question is, do you think I've exhausted all options, or should I bite the bullet and try the other board?

Tested with no RAM inserted, no beeps from the motherboard. Went and got my PSU and connected it instead, same results. At this point, I'm certain that the PSU is good, which really only leaves the motherboard and CPU....

I decided to just go for the motherboard switch since I didn't see any way around it. Got the old one one, removed the heat sink, thermal paste looked good. Opened up the socket and the CPU orientation was correct. Then I pulled out the CPU to put it in the other board. Looking closely at the socket, some of the pins looked a bit funny in one row. I compared to the other socket and, sure enough, there were several bent pins in the socket we were trying to use. CPU insertion was actually the one part of the build I wasn't present for, though I don't know if I would have caught it myself. Anyhoo, we're gonna get it all put back together with the other board and hopefully our troubles will be over.
