[SOLVED] Unexpected shutdown after upgrading graphics card

[oxidaxion]

Hi, after installing a new graphics card, my computer has been experiencing a whole slew of problems. Firstly, after trying to play a game for about an hour, the monitor would shut down (presumably to overheating). After trying to fiddle around with settings in the AMD WattMan, the computer would show visual glitches before reverting the changes made. Finally, 3 days after installing the new graphics card, my computer unexpectedly shut down and will not turn on anymore. My computer's specs are listed here: https://ca.pcpartpicker.com/list/vT9Ggw

The graphics card currently listed there was originally an R9 380. What should I do to fix this?

That motheboard is definitely not one I'd suggest running a 8350 on I wonder if you finally killed the vrms on it.

Before it would shut down would game play get choppy?

Gameplay did not get choppy, it seemed like everything was running properly. How do I check if that is the case and what are the next best steps to take?

Will it boot without the GPU? If it's the vrms another motherboard is all that'll help. Could be you butchered a setting in wattman and harmed your GPU possibly. So see if it'll show signs of life without gpu plugged in. Does it do anything when you hit the power now?

The PC would not turn on when I pressed the power button while the GPU was plugged in. After removal it turned on and went to the login screen.

Hmm.. try resetting the cmos, resinstalling the GPU and see if it'll work.

How do I go about resetting the cmos?

Unplug power supply from wall. Pull battery out of motherboard, hit power button a couple of times. Let it sit 5 mins, put battery back in, plug back into power supply, and see what happens

I performed the steps as instructed, and now the power button is on but no fans are spinning and nothing is displayed on my monitor. What does this mean?

 

[Supahos]

Sounds a lot like your gpu died, any idea what you did in wattman?

The only change I tried to make was to increase RPM when the gpu reached certain temperatures since what I was initially observing was that the gpu was overheating and causing the hdmi to stop working.

 

[Supahos]

Well now I'm stuck... Part of me thinks the power supply could be messed up and your first GPU wasn't bad the other half suspects your current GPU had issues....

It seems like it would be the latter, no? When I removed the GPU the computer would boot properly but with this rx580 it would not boot at all...

If the 12v rail the PCi connector is on is toast you'd have probably the same result

So does that mean the motherboard is not working then? Sorry, a lot of the terminology for computer parts escapes me.

 

[Supahos]

No I mean the power supply could be failing to provide the correct power needed to run the GPU. Or the GPU itself could be bad. It's impossible to guess which unless you have a spare psu or working GPU on hand to troubleshoot

I don't have a spare psu but I do have the old gpu that I replaced. I plugged that in and the pc would not turn on at all, so would that indicate that the psu is shot?

 

[Supahos]

I thought the old gpu was toast too. If it was still functional the most likely it's the psu

Okay, I'll go about getting that replaced. One of the prior things you said earlier was that this motherboard was not a good one to support the processor I had, is that something I should replace as well?

 

[Supahos]

If it's not choppy gaming you're probably okay. When you get it back up and running I'd consider trying to undervolt the cpu if possible to take some stress off the vrms on your motherboard

And I would do that through wattman settings?

 

[Supahos]

No you'd do it in bios. It's just slightly lowering vcore.

Okay, thank you for all of the help!
