You have a very good psu, so I doubt it is the problem, however you could check to see if the cooling fan is spinning and keeping the psu cool (although I doubt that is the case with that psu). Your temps are well within thermal limits so your not experiencing thermal throttling. Have you installed any new hardware recently or changed any setting in bios? You should also check your task manager before and during game play and see if another program (not the game your running) is using up a bunch of CPU or RAM.
I think the next best step would be to download Malwarebytes (from official web site) and run a custom scan selecting the hard drive you have windows installed on. It will scan every file of that drive and make sure you don't have any malware or PUPs (potentially unwanted program) that my be causing instability.
Have you recently updated to Windows 10? If you did upgrade did you do a clean install of the OS after updating?
The last thing I can think of right now is what motherboard do you have? A possibility is some value boards have poor power phase and your board itself could be dying. But try all the above things before we even go there.
Around 4-8 months ago I got a new hard drive and a new PSU, still running Windows 7 same as before, no settings have been changed in BIOS recently or longterm that I'm aware of, I'll check task manager on Witcher 3 now, I'll also do the malwarebytes when I have time over the next few days and update you on both the result of that and the task manager thing.
My mobo is a H87-HD3.
When you run Malwarebytes make sure to do a custom scan of the entire drive where your OS is located (usually C). Remove any malware (of course) and any PUPs it finds as well. PUPs (potentially unwanted programs) can run in the background and hog system resources causing decreased performance.
Ok so quick update, my GPU just violently siezed up and died. Pulled it out and computer runs fine and on the integrated GPU on my CPU and nothing seems too corrupted (so far) but case solved I guess, GPU is the culprit.
Gonna take my PC round to a local PC shop and have them run a diag on the GPU and the PC to see what went wrong but it looks like I'm going to need a new GPU.
