I'm having issues with games randomly crashing without any errors, but sometimes with a crash reporter for the software appearing. It's not a new computer by any means, but also software that used to run perfectly fine started crashing.
GTX970, i5-3570K, 16 GB RAM, Windows 10
Could someone please help me with advice on what I should do to try and identify the cause?
I've monitored the GPU temperature, and that doesn't seem to be the problem. It's steady just above 60 degrees Celsius.
I started considering the PSU since I purchased a computer fully assembled and I did replace my GPU a while back (what do I know? Maybe they put in a PSU that just had enough power to supply their build? But as I'm not that smart, I did no investigations. I just crammed stuff in there). And I've also installed an extra SSD, but I'm pretty sure the crashes didn't start until much later. What I do remember, which might just be a coincidence but I can't really let it go. I'm pretty sure the first time it crashed was when I did a HUD modification in Elite Dangerous (just editing a text file to change the color) which didn't work, and then the game crashed shortly after starting it up. I backed up my changes and then the game (Elite Dangerous) started crashing randomly, and more frequently over time. It never happened with the game before. It then also started in other games that always ran without problems previously. Like WoW and GTA V. All heavy 3D games are now crashing. I've recently tried Farcry 5 which will never run more than 5 minutes.
It also happens on occasion when I'm modelling in Blender. Most games that are light or not 3D at all, doesn't seem to have the problem.
Drivers and such are up to date. I also took out the GPU and ensured there isn't any collection of dust anywhere.
Anyway, long rant with little useful information, and I don't expect anyone to find a solution for me. But any advice on what diagnostic software to use (and what to look for when using them), logs to review, or any other "standard" solutions of any kind is much welcome.
