Yeah time drift/broken vsync is also a sign your GPU or driver is failing. On a new PC, if you're having issues and you've:
- Ensured all your drivers are up to date
- Ensured your BIOS is up to date
- Your GPU isn't loose and secured in its socket
- Your Windows is up to date (although this would very rarely cause a GPU issue)
- You're not running some "Ultra gaming boost pro" software (usually comes with store bought PCs)
RMA/return the PC. You should not have any issues out of the box like this. A bluescreen and sudden end of a log is a sign the hardware/software failed and Windows killed the game (in case of the crash) or itself (blue screen of death) to prevent OS corruption.
Now, it COULD be overclocks (auto boost, etc.), memory timings (XMP), but if you bought it from a store you shouldn't have this issues out the box. Something isn't right.
