Shows intermittent flickering and restarts when under stress
Shows intermittent flickering and restarts when under stress
I’m trying to determine if the problem lies with the power supply, motherboard, or graphics card. Whenever I increase the workload on my PC, the screens flicker and it restarts frequently—sometimes fully, sometimes just locking up briefly. After a reboot, one display may appear at a distorted resolution with artifacts, while other tasks like gaming and browsing work smoothly. Running Prime95 didn’t trigger a restart but caused flickering. The fans and lights keep spinning without powering down during restarts. This isn’t my brand new machine; it’s five years old. I’m considering replacing a component to fix the issue but want to identify the culprit first.
Have you verified the temperatures? It's possible the system overheats under load. You might also investigate using replacement components. If you lack any, consider asking a friend to lend their PC. Check the GPU on their machine, test it in yours, and repeat for the PSU and other components.
The screens release or freeze the PC and restart before I can even press alt+tab to check temperatures. I was able to capture a peak during Prime 95 when everything seemed normal. After opening the case, I cleaned it thoroughly just to confirm. Since I don’t have anyone nearby to test replacement parts, I’m planning to visit MicroCenter after work and pick up one of each. I’m hoping swapping one component will fix the problem.
