Troubleshooting a Non-Starting PC: What to Do When Your Computer Won’t Power Up
If you’ve ever faced the frustration of a computer that won’t start, you’re not alone. Recently, I encountered a similar issue after attempting some routine cleaning on my PC. Here’s a breakdown of what happened and the steps I took to troubleshoot the situation.
The Situation
After a long period without maintenance, I decided it was time to give my computer a thorough cleaning. During this process, I laid the PC on its side to remove dust buildup, but I soon realized I didn’t have enough canned air to finish the job. As a result, I left it in that position overnight. In my enthusiasm to clean, I also attempted to detach the CPU cooler to access the heat sink. However, it didn’t come off easily, so I secured it back in place.
The following day, I was eager to power up the computer, but I was met with disappointment. While the fans, including the CPU fan, started running, the GPU showed no signs of life—no lights or power were detected. Moreover, my keyboard and mouse remained unresponsive, and there was no display signal to the monitor.
Diagnosis Steps
Determined to find a solution, I went through a series of checks:
-
Power Specifications: Although the fans powered on, I noticed that the GPU wasn’t receiving power, which was concerning.
-
Peripheral Functions: I found that the keyboard and mouse did not light up. This lack of response suggested an underlying issue with the motherboard or power supply.
-
Power Button Issue: Another unusual problem arose: the system wouldn’t turn off when I pressed the power button. However, I noticed that it could still power a small USB fan connected to various motherboard ports.
Seeking Help
At this point, I would greatly appreciate any advice or insights from experienced users. I suspect the issue may not be as severe as it seems, and I’m hopeful that my PC isn’t beyond repair. Any recommendations on troubleshooting steps or potential fixes would be immensely helpful!
