The new GPU performs well for benchmarks and stress tests, yet causes the computer to freeze during games.
Hello, I upgraded my GPU from GTX1060 to GTX1070 to delay purchasing a new one for a while. (i7-7700; 16GB RAM; Windows 10 64-bit on SSD). The newer GPU easily passed stress tests for hours (Furmark). Under load it stayed stable up to 70°C. However, when I run games like CS2 or RDR2, my PC freezes after about five minutes. The GPU itself isn’t overheating (error code 0x8000400000000002 - Kernel-Power 41). My power supply is 600W, and the difference in power draw between the two GPUs is around 30W. This caused repeated freezing—five times in a row—until I unplugged it briefly. After that, everything worked again. (After the stress test, games froze for five minutes.) I switched back to the GTX1060 and CS2 now runs smoothly. Reinstalling all NVIDIA drivers didn’t help. Any advice would be appreciated. Thanks a lot.
Which 600w power supply model are you referring to? The distinction between cheap and premium units often determines whether a card powers on or not.
It's a Zalman ZM600-GSII with 600W power. The interesting part is that the PC handled benchmarks smoothly for about 30 minutes under stable conditions, but performance drops significantly in actual gameplay, lasting only a short time.
It turned out the issue wasn't with the PSU, but with the UPS—which I hadn't mentioned before. Now I'm connecting the PC straight to the wall, and the 1070 is working fine. Thanks for the advice; it was a power problem.
The malfunctioning UPS could cause issues. It’s still advisable to consider swapping out the PSU if you can, since the current one is of poor quality.
