OS - Windows 11 CPU - AMD Ryzen 9 5950x GPU - RTX 3090 Motherboard - PRIME X570-PRO PC is built with a custom water cooling setup. I previously posted about resolving this before, thinking the system was stable, but problems kept returning. I've been experiencing weeks of instability. My machine suddenly goes black and crashes frequently. I suspect hardware faults involving the motherboard, power supply unit, or graphics card. Sometimes it flickers, especially during operation, then crashes briefly afterward. Occasionally the screen turns dark but the PC restarts partially until I force a restart or it fails again. Putting it to sleep makes it behave erratically when I power it back on. Crashing events trigger the motherboard to emit a bright white light, and the displays stop working until I disconnect the system and reconnect the monitors. No mini-dump files appear; Event Viewer logs errors like 141, 117, and 41. What I've tried: - Fixed Windows - Reinstalled Windows - Cleaned driver installation with DDU - Replaced RAM, CPU, GPU - Checked power cables - Applied new thermal paste to CPU - Ran memtest86 on RAM (clean results) - Vacuumed dust from the PC - Swapped surge protector - Changed HDMI cable on one monitor (others use DP) - Updated BIOS, graphics drivers, and chipset I’m unsure if the issue stems from the power supply, GPU, motherboard, or another component. However, the PC remains stable during normal use, not when gaming or waking from sleep.
Check your power supply unit and run Furmark to identify the GPU's hotspot.
Your EVGA 1000W is still working but your PC keeps crashing and the motherboard is flashing a white light.
You just connected the power supply again after turning it off and on, but you're not sure what will happen next.
You might find alternative methods to evaluate your GTX 1070 without connecting it directly to your PC. Consider using a remote testing setup or a virtual machine.
I could possibly detach the GPU a bit and fit the 1070 into a different port.
I successfully obtained the 1070 In. It’s a much thinner card. I’m ready to run the system tests. For stability, I should be aware of any recommended procedures or checks.
I tried a bit with the 1070 and found it runs much more stably, though the screen sometimes goes black briefly during unigine superposition tests. It seems the 1070 has a lower power rating, so it’s possible your PSU might still be underpowered.
