After installing new GPU, red screen mid game. PC no longer outputs video.

Dying_Flogmeat · Feb 1, 2016

Installed R9 Fury, played Star Citizen for an hour- Screen turned red and I had to force power off the system. GPU was too hot to touch.

Took it out and reinstalled mobo to change some screws.

When everything was back together, the PC would not go to post or output video, though all fans and lights worked, with the notable exception of the blue led' on the GPU.

Using the asus m5a97 r2.0 GPU, and fx 8350 CPU.

I have installed old GPU (280x) and the system still will not output video or audio, problem is not GPU specific I guess.

Using a brand new EVGA PSU, 750W. It is fully modular, so I replaced the CPU power cable. Problem persisted. I guess it's either a CPU or Mobo problem. What's the likely fault, and is it covered under warranty?

I just plugged everything into my old PSU with old GPU, same issue. I suppose it's definitely not a PSU thing either. I'm going to try and reseat my CPU, but I still have no idea what could have gone wrong if it was the CPU. The CPU cooler was definitely working, and even if it wasn't, you would think the PC to shutdown before any damage.

I'm not familiar with how the motherboard could be at fault, but it seems to be the only unknown.

Please clear your motherboard's CMOS and see if it brings the display back.

Reseated CPU and the problem still persists. Didn't notice anything abnormal about the CPU. Will test it on an old motherboard later. In the meantime I will put the GPU and PSU in an old core2duo build to confirm that the GPU and PSU are fine.

Dying_Flogmeat :

Sure. Before you do that, also consider clearing the CMOS just in case.

EasyLover :

Just saw this comment, doing now. Thanks

Dying_Flogmeat · Feb 1, 2016

Have cleared the CMOS, still not resolved

EasyLover · Feb 1, 2016

Oopppssss! Proceed with testing as suggested by yourself.

Dying_Flogmeat · Feb 1, 2016

So, despite being bottlenecked by an eight year old CPU (that still runs modern games, mind you!) It runs absolutely normal on the old 44nm core 2 duo and respective mobo.

This is certainly a motherboard fault, right? Luckily it's just within warranty right now.

Better check your graphics card on some other system to see if it is working properly. We need to eliminate each component from the possible list of faulty components.

What did you change? Why? Maybe change it back ...

Dying_Flogmeat · Feb 1, 2016

Sorry, I tried to turn it on and it did not post, so I decided to uninstall the motherboard and rescrew it/plug everything back in.

Dying_Flogmeat · Feb 1, 2016

Also it is definitely not the grphics card or PSU at fault, both are working normally in another system.

I'm getting my hands on my old motherboard today to check if the motherboard is the problem, or the CPU.

Dying_Flogmeat · Feb 1, 2016

After testing the CPU in another motherboard, I have discerned that the fault is indeed with the Motherboard, the PC powered up as normal with the same components on a different motherboard.

Off to Motherboard Heaven with you, M5A97.
