PC won’t turn on help
I activated the power button on my PC but received no response. I attempted to use a screwdriver on the motherboard to bypass it and also tried the paper clip test on the PSU—fans spun and the pump started. Given that I built my system four months ago, this seems unusual. My motherboard isn’t lighting up, though there’s a small screen connected via USB showing a blinking blue light. Recently, I changed the PSU power switch, held the PC power button, then flipped the PSU switch while keeping the PC on—then the computer booted up. This behavior feels risky and unexpected.
The PSU likely entered protection mode and reset after flipping the back switch off. You didn’t need to keep pressing the power button while toggling it. Your power supply seems still functional. The most likely cause is an abnormal voltage spike on the power line, triggering its safety protocol. It’s probably a one-time or occasional issue. If it occurs repeatedly, you should address it. Since your machine is expensive, do you have a UPS in place? It would be wise to consider one for added protection. A few hundred dollars can safeguard thousands of dollars worth of equipment from power fluctuations. Good luck!
I expected the PSU to work even with software installed, but the way you held the power button seems to have resolved a CMOS issue.
Essentially followed what ISPs require consistently. Unplug the device, wait 30 seconds, then reconnect. If this is the first occurrence, don’t take any action. This has happened randomly to my computer several times, and the system has remained functional afterward.
