Unstable fluctuation...
I'm experiencing strange black screens during game launches. The PSU seems adequate, but I suspect the RAM might be the issue. I've tested both GPU and CPU under stress, and they handled it without problems. I recently replaced two RAM sticks with the same frequency as the others—same brand, different models. My Kingston FuryX 2x8GB and HyperX Beast 2x8GB (both DDR4 3200MHZ CL18) are identical in specs. The system worked fine a few days ago, but after hours of gaming it froze. A wattage meter showed the PC drawing between 500-540W before crashing. Could the GPU be the culprit? I installed a riser and it still flickers—lights stay on, then turn off. Did the GPU fail suddenly, or is there another problem? The CPU came with minor overclocking, and I haven't noticed any issues yet.
When you mention black screens, it refers to a restart or blue screen that keeps appearing until you reboot. If you need to check RAM, add one stick of RAM across all four slots. To rule out the Riser cable, connect directly to the GPU via the motherboard. I suggest removing unused peripherals like external drives and webcams now. Also, consider a Windows reinstall if your system appears corrupted—it's simple to do.
Performing a Windows reinstall, I removed the new RAM sticks I just installed, but the system still crashes. After reinstalling Windows, if it keeps crashing, I’ll try using the riser. The PC freezes and the screen goes black; it doesn’t come back after a few minutes, so I have to turn it off and on again.
Stress tests and real-world use differ significantly. A game can cause GPU and CPU demands to change based on scenes, influencing power consumption constantly. This might overload your power supply beyond its limits. In my view, if you consistently overlook the PSU... it’s unlikely we can rule out that risk entirely. Sudden power spikes from transients will force your PSU to operate at maximum capacity, often exceeding it. NVIDIA suggests 750W for a 3080, but some users still face issues with that wattage during transients. I’d advise going with 850W to avoid those problems.
I understand, but I’m keen to eliminate all other possibilities before investing 100€ in a new PSU. The issue is it’s already started running several games.
Windows were reinstalled a couple of times without issues, saved files were restored and then problems resurfaced. Opening the game causes the PC to crash. Planning to take out the riser and connect the GPU straight to the motherboard.
Checked the drivers from AMD, installed them, and verified if any AMD drivers were present. Ran a full driver reinstall. Turned off VSync and maintained the same refresh rates on different monitors. Provided thermal images of the GPU to monitor temperatures. Ensured we’re not approaching a thermal limit that could cause shutdown.
