Hi everyone! I recently upgraded my PC with a new power supply and graphics card, but I'm facing a strange issue. The staff at the store demonstrated that the computer was working fine, but when I brought it home, it only stays on for a brief period—between a few seconds to a minute—before shutting down completely with no error message. I've already tried different power cords and multiple outlets in my apartment, but the problem persists. Does anyone have insights into why this might be happening specifically in my home or suggestions on how to resolve it?

Sounds like a power issue at your place. Maybe see how it performs at a friend's house or get a UPS. It could just be that your apartment isn't supplying consistent power.
Check your internal connections too; sometimes cables can get loose. And have you noticed any power surges or flickering lights at home? That might indicate deeper electrical problems.
I’ve noticed some flickering, so that might tie in with these issues.
Keeping an eye on those signs can really help with diagnostics!
It could also be your monitor. I had a similar issue, and switching to a different monitor solved it. If possible, test your monitor elsewhere or try a new one at home.
Have you tried unplugging everything except the essential components like just the monitor and power? Sometimes outside hardware can cause issues that weren't present during the test at the store. Just a thought!
Great suggestion! It helps narrow down if it's a specific accessory causing the problem.
Yeah, I had something similar happen. It turned out to be a faulty keyboard causing my PC to crash.
You might want to invest in an uninterruptible power supply (UPS). These battery backups can help regulate the power quality and prevent shutdowns due to unstable voltage in your home. It’s worth considering if you’re still troubleshooting.
I’m looking into it too! Just don’t want to buy one until I've checked other options.
Definitely a good idea! Trying it elsewhere could help pinpoint the issue.
