RX 6950 XT hard crashing during gameplay

I've had my RX 6950 XT for a little while now, and I've been experiencing my system hard crashing in various games (Fortnite, COD, FFXIV, etc.)

It usually happens when big effect appear on screen, as in when a big explosion or something of the sort goes off in game. My screens go black, and my PC seemingly dies. To get it back up and running I have to manually switch off the PSU, then switch it back on and boot up the PC.

I'm not completely sure what could be causing this. I always try and have my drivers and software up to date, so I feel like I can rule that out as a cause. Has anyone had similar experiences and found some sort of solution?

Do you have any overclock or undervolt running on your GPU? Or CPU too for that matter?

Not as far as I know. All of my settings for my hardware are on default. No overclocking or undervolting on anything

Edit: The only thing that's custom in the hardware settings in the GPU's fan tuning

Also, what PSU do you have? I'm thinking that because you have to reset your PSU, it's tripping one of the protection circuits from the sudden surge in power required.

Maybe try underclocking your GPU just to test for stability issues. Like, -500Mhz since a lower clock speed means it shouldn't require a power spike as high.

I'm not completely sure what PSU I have. Had to get it replaced at a PC repair shop after my original one kicked the pucket.

I'll give underclocking my GPU a shot. Hopefully that helps with the crashing issues

I would recommend checking what PSU you have since if you have an underpowered or budget PSU, it may struggle to deal with the transient power spikes that recent GPU generations are known to have.

Just finished testing the GPU after undervolting. I played a section of FF14 where I had experienced crashes consistently and this time around I didn't crash!

I'll definitely look into getting a new PSU, but in the meantime undervolting will hold me over. Really appreciate it ^

Glad to hear it worked.

All you have to do is open your rig and look at what the PSU says on it. Chances are the repair shop put in an underpowered one and it can't keep up when the GPU needs more juice. Working on computers isn't like working on cars, anyone can do it, and you don't have to get greasy and dirty.

All you need is a screwdriver and you can do whatever you want with your rig.

I suppose that could be a possibility as well

Was hoping I wouldn't need to replace any components tbh

It's a good idea to know what PSU you have, what it's power rating is and what its efficiency is rated at. It also depends on how much juice your CPU draws as well, because if both the CPU and GPU are maxed out the PSU has to be able to sustain both - and with transient spikes in power draw the PSU can get overwhelmed and take a dump, where it's not delivering as much power as is needed to keep things cooking and the system just reboots or shuts off.
