This is a TDR problem, update your video drivers
Common issues that can cause a TDR:
- Bad memory
- Insufficient/problematic PSU
- Corrupt driver install
- Overheating
- Unstable overclocks (GPU or CPU)
- Incorrect MB voltages (generally NB/SB)
- Faulty graphics card
Things to check first:
- Run memtest (memtest.org). This should complete with NO errors.
- Check your PSU ratings. Is it providing enough power, and most importantly enough Amps on the 12V rail.
- Check temperatures. Its important you check these at load, which is generally when a TDR event will occur. Cleaning your system of dust can help temperatures significantly. Common sense will normally tell you if something is too hot, but if you aren't sure, the information is generally available online.
- Test with stock clocks. This includes memory, CPU and GPU (even factory OC'd cards). Best to try each separately so you can be sure if one solves the issue.
- Try graphics card/cards in another computer if you can.
This is more likely a driver issue or a faulty graphics card
