Could it be the power supply unit, or the graphics card?
I recently acquired a used graphics card (GTX 750) and successfully installed driver version 833.13. However, when I configure the NVIDIA control panel for maximum performance, my computer subsequently freezes. When I switch to a power-saving setting, the issue disappears except when running demanding games like Prototype 2 or NFS Carbon, which consistently produce a “Video_tdr_failure” error. I suspect the problem might be related to my power supply unit, as it’s an unbranded model. My central processing unit is two years old, and my system includes: an AMD A6-6400K processor on an A68HM-E33 motherboard, 4GB of 1600MHz DDR3 RAM, an MSI GTX 750 with 1GB of overclocked memory, a 700W generic power supply, and I’ve also updated my BIOS to the latest version and reverted to Windows 10 build 10586.
Your power supply readings are inaccurate.
You require a replacement power unit.
That’s all there is to it.
The power supply unit might be the issue.
I recommend using HWINfo to examine the voltages, specifically while it’s under stress.
You should ensure that the readings are between 12, 5 and 3.3 volts, with any variation of less than 5%. Additionally, monitor your temperatures; the CPU should remain below approximately 70 degrees Celsius, and the GPU should stay under 85.
I observed that my graphics card’s temperature remained consistently at 40°C, whereas my central processing unit reached temperatures between 75 and 85°C during gameplay of Prototype 2 at a resolution of 640x480. Voltage levels were recorded as 12.2xx for V12, 4.2xx for V5, and 2.6xx for V3.3. Subsequently, after approximately fifteen minutes of operation, the system failed, but without generating a blue screen error. It then reverted to the Microsoft basic display driver, suggesting that reinstalling the NVIDIA driver resulted in a system crash.
OK so I think it really is the PSU because sometimes I'm successful on installing the GPU driver but then when I use the GPU to a game it crashes but when the nvidia driver is not installed (which it doesn't consume voltage) the windows doesn't crash
Your electrical measurements are inaccurate.
