Hi, I built my own PC a few years ago for work and light gaming. It works most of the time, but crashes randomly in games. Back then, it was mostly Star Wars Battlefront 2 which I played alone, so every game would crash sometimes while playing other games fine for hours. Now that I've expanded my gaming, it happens with all games when loading from Epic Games Store like Control and Frostpunk, or Total War. They just stop working after a bit of time. I've tried many steps to fix this, mostly searching for specific issues, but now I think the problem might be more widespread in my build. Here is what I have: an MSI B450M Mortar Max M-ATX motherboard, Corsair Vengeance DDR4 3600 RAM, two sticks of 8GB each from Crucial MX500, a 250GB SATA III SSD, a Gigabyte GeForce GTX 1660 SUPER OC with 6.14 GB of GDDR6 memory, Seasonic S12 550W Bronze power supply, running Windows 10 Home. I did the basic stuff like updating drivers and BIOS. I ran some graphics card testing software which said there was no overheating or issue during tests. I also tried underclocking to see if that helped—it didn't work either. The PC doesn't crash when doing anything else; it seems to be a GPU-related problem. Any ideas on where to go from here?

Hey, thanks so much for getting back to me! Just in case you can figure something out, maybe I could take out one stick of RAM to see if things work better. If that doesn't help, we could just run it with only the other sticks left.

There is one simple way to do this. Sure, using something like Prime95 or another test program sounds kind of scientific. But even then, it's still just checking one memory stick at a time so you can find which bad one there is.

So I checked Memtest86 and it passed without any problems. Are you looking for more tips?

How long does one pass take? Usually, I won't call something stable until it has gone on for a full 12 hours. Back when I ran Prime95 with RAM that was known to be bad (found within the first 10 minutes via F@H of all things), this stick lasted exactly 19 hours before giving up and making an error.

what you're talking about sounds like the problem I've been having for a long time, so why not help me out? find some crash dump files from games, look at them with debug tools like Windbg64, tell us what errors are in there, and we'll know if this is causing my issues.
