System unexpectedly powered off and restarted.
System unexpectedly powered off and restarted.
I've faced this challenge over the past few months. It's a brand-new setup, less than a year old. The main issue is that my system frequently powers off unexpectedly—while playing games, editing, or just idling while watching YouTube. It doesn't always happen randomly; sometimes it's just a sudden restart after doing GPU-intensive tasks, then it works perfectly for a week or so. After that, the problem reappears without any clear warning.
I've tried several fixes:
1. Swapped the motherboard once since it's still under warranty.
2. Replaced the CPU.
3. Installed a UPS because power outages are common in my area.
Also, I noticed the LED on the motherboard stays lit during shutdowns or reboots—only sometimes—and when the system shuts down, the keyboard lights stay on while the mouse doesn't. The fans run normally, but the display flickers. Sometimes it disappears completely, and other times it stays on.
The RAM seems fine—display issues are inconsistent. It could be a GPU problem, PSU fault, or DRAM LED malfunction. I'm unsure which part needs replacing. Could you help me identify the exact component? Thanks!
Temperatures stay within typical ranges near 56-60 during gameplay. I also refreshed the motherboard BIOS a few months ago after getting a new CPU.
I've encountered a comparable but distinct problem, though it seems software might be the main culprit rather than hardware. Over the past two years, I've been trying to pinpoint the issue on my PC, and I haven't eliminated hardware as a possibility. If you have access to another machine, swapping components could help identify the source. There are also various tools available that test individual parts. Wishing you success in resolving this challenge.
