The game was running fine for many months or years. It basically almost never crashes.
I have Win 7 64 bit.
I had to move things around because I made a HDD configuration change. I copied from one HDD to another (D: to E:).
I copied back to the original location (D:).
Now, the game crashes randomly. Perhaps in 1 min or 10 or 20 min.
What happened? I think some files were corrupted.
I used the Origin check game feature. It did not detect any problems.
I ran memtest86 for 1 h. RAM checks fine.
Event viewer sometimes says that it crashes in a nv DLL, so I updated the graphics driver (uninstall drivers, reboot, install new driver, reboot).
Sometimes, it indicates a crash in MSVCR120.dll.
Sometimes, it does not know.
What is going on?
I ran Cinebench R15 and R20. I ran Duke Nukem Forever. I run Firefox for 10 h and more.
I leave the PC on for days and Win 7 does not crash.
