System unexpectedly powering down.
System unexpectedly powering down.
I completed my first PC build and followed all the steps. After using it, it would sometimes shut down randomly—either restarting or powering off completely, but the RAM lights stayed on. My setup includes a Ryzen 5 5600X GT 710, and I plan to get a RX 7600 soon. Until then, I’m using a GT 710. I’ve tried swapping out the GPU for another GT 710, but none resolved the problem. The Corsair Vengeance RGB RS 8x2 is connected, and changing the DOCP settings didn’t help. My PSU is an Asus Prime B550M-A with NZXT C550, running Windows 11 64-bit. I’ve installed drivers via Asus Armoury Crate, but the issue still exists. The BIOS was updated to version 3404. It seems the problem might be in the BIOS or Windows itself.
I’m just getting started with this stuff but I’m used to fixing things. You could try running the system with just one stick of RAM to check stability. A persistent black screen with loops usually points to RAM or power supply issues. Since I’m new to building PCs, I’ve picked up a lot quickly. Another unlikely reason could be the motherboard model—your 710 might not support modern games. If software updates keep dropping and older phones are still working, it’s possible the hardware is outdated. Using apps like CapCut or Adobe Mobile on such a setup often causes crashes mainly because the processor can’t handle today’s demands. If I had a 3D Mark II, those issues would be less likely. After the black screen, it probably relates to GPU performance or power delivery.
This seems to point toward the most probable cause…just a couple of straight motherboard connectors managing power, acting purely as binary switches. They either function or they don’t, and you’d need a screwdriver to swap them out. It’s definitely possible, but perhaps the connection setup is the real problem—being partially connected to two pins isn’t very common. I’m not suggesting you go all in, but testing it by disconnecting the power cables and checking if the system resets could help. If it does, the case wiring or PSU/GPU might be the issue. If it fails on a dummy board, it’s likely your RAM or graphics power supply is the culprit—especially if you’re aiming for Last of Us on a 710, which would probably cause frequent crashes.
Thank you for your feedback. I tried using a screwdriver to boot up the PC, and it’s now running smoothly without any problems. I realize it might be too soon to say for sure, since it hasn’t been long since it was on, and I haven’t been doing heavy GPU tasks at that time. Based on what you described, it seems like the problem might still exist even after starting with a screwdriver. Could you confirm if the power buttons were wired correctly or if there’s an issue with the case?
