PC Won't POST After Turning On
I increased my CPU speed in the BIOS momentarily. While saving, it stopped working, so I turned it off. When I powered it back on, the PC didn’t show any screen, the keyboard and mouse didn’t light up, but the fans were running and the LEDs were on. No display detected. Assistance needed?
It might be an issue with the settings, and the PC isn't letting it boot from unstable voltage levels. Reset the BIOS by clearing the CMOS to return it to the default state. Check the motherboard jumpers (do you have them? What board, CPU, OS?), or remove the CMOS battery for a short time, then press and hold the power button to discharge the capacitors. Ensure the power supply is off or unplugged from the wall. Reinsert the battery and test again. If this fails, consider replacing the CMOS battery. If problems persist, the BIOS could be corrupted.
