I agree with the other poster this seems like a hardware issue.
- Start with a general battery of hardware tests.
- Memtest for memory. One or two errors in a full run is OK, more than that is not. A full run will take a few hours, just run it overnight.
- Furmark for GPU. Look for visual glitches or crashes.
- Prime95 for CPU.
- If those fail to point out the issue. Swap components into another system. This will allow you to eliminate (or confirm) them as the issue. Example, does this GPU have issues in a different system?
