I recently ordered a new motherboard (AB350 Gaming 3) with a new CPU (Ryzen 5 1600) and RAM (LPX Vengeance). The motherboard has a little disco before boot where it tests the CPU, RAM, GPU (labelled VGA) and then Boot. For each test, a separate light goes on and if there's no problem the light goes out again. However, with my current GPU (ASUS R9 270x DirectCU II ) the light doesn't go out. With an older GPU (Zotac GTX470) the system boots fine and everything functions. Seems like a clear cut case of a dead GPU, however my R9 270x still works just fine on my older motherboard+CPU+ram combo (P7P55-M with i5 760). When the PSU gets power, the R9 270x shows green lights above where the power is connected and when I try to boot, the fans spin. Not sure if that helps, but I thought I might as well mention it

 

As for things I've tried,

I tried plugging it into a different PCI-E slot on the motherboard, however a friend said that was a bad idea since only the top one was PCI-E 3.0.

I tried using a brand new PSU (so I've tested it with two, both of which should be plenty to power the new system at 550W since pcpartpicker only rates it at about 350)

I updated my new motherboard's BIOS to the latest version.

I tried changing the PCI-E settings from Auto to Gen3, in case it didn't recognize the R9 270x as gen 3.

At friends recommendation, I tried turning off XMP but it was already disabled by default.

I think this video from JayzTwoCents shows the exact problem I'm having

 

Sadly he seemed to have no idea of what caused the issue and I can't find an update about it. For him it's probably not such a big issue since he can just run another card on that system, but I can't magically switch my GPU for an identical one

i just had a mobo that was hanging on the bios GPU test.   I reset the cmos, then it rebooted fine.

Could you post with other GPUs?

 

Is there a difference between clearing CMOS and doing the Reset Defaults in the BIOS itself?

 

EDIT:: Well I just cleared CMOS and I got something new with my R9, after hanging on the VGA light, it goes back to CPU light, clears it, goes to ram, clears it, goes back to vga and hangs again, after doing that twice it just kept hanging on VGA again.

 

Thanks for the suggestion though
