I built a PC over the summer using all new parts and have been having the issue described above since pretty much the start, I have tried a few things/ just put up with it but it hasn't helped. There isn't a regular time this happens and isn't limited to a single use, happens in CPU intensive games, GPU intensive and even whilst running crypto mining software. Another potential useful detail is the power led indicators on the GPU all turn off when this happens. Very rarely I may get a blue screen with the thread stuck in device driver error message if that gives any indication of the issue.
My specs are:
Ryzen 5 3600 - Stock cooler
MSI Vega 64 Air Boost
Corsair Vengeance LPX 2x8GB 3000MHz C15 RAM
Intel 660p 1TB NVMe SSD - Boot Drive
MSI B450 Gaming Plus
Corsair CX750M 750W Bronze PSU - Grey label version
Windows 10
Some of the things I have tried to try fix/ find the cause are (in no particular order, just trying to remember them all):
Update/roll back graphics drivers including using DDU and safe mode for this
Increase/decrease power limit of the GPU using wattman and afterburner
Update windows
Update/roll back BIOS (limited to the first BIOS that supports Ryzen 3000)
Increase/decrease RAM frequency/timings
Ran memtest86 multiple times with no errors
Ran prime95 for multiple hours with no issues
Moved GPU to different PCIe slot
Checked temperatures during use and nothing abnormal
Took side panel off and turned a fan on to cool parts more just in case
Used sfc and dism commands to check windows files (at first there were corruptions but now it comes up clean and issue persists)
Used windows install media to repair instillation
Checked PSU voltages using BIOS/HWiNFO64 and all seem within reason
Checked event viewer for any details with the only issue being the one related to windows not shutting down properly due to having to hold the power button to turn it off
Tried daisy chain and separate power cables to GPU
Inspected parts for physical damage
Cleaned dust on parts
Ensured parts seated correctly
The performance is as expected outside of this issue, there is no physical warning of this crash and due to some of the things listed above, I don't think it is a hardware issue but can't rule it out. I don't have any spare hardware to try out and I need the GPU to get a display output so it has to stay in the system. I would prefer to avoid getting replacement parts due to being at university and needing my computer but if push comes to shove it is possible as a last resort.
I hope that gives a good overview of my issue and any and all help would be appreciated. If any additional tests can be done or more information needed just let me know and I will see what I can do.
