What could be causing your PC to restart issues?
My PC functions normally until I restart, then it appears to restart itself briefly before turning off and back on. During these moments, the American Megatrends screen appears, prompting me to press F1. This behavior occurs occasionally after restarts but remains bothersome without a clear explanation.
Update your update to reflect complete hardware details and operating system specifics.
Power supply information: voltage output, model, wattage, age, and current condition (original build, new, refurbished, used).
Storage devices: type, manufacturer, storage size, and current usage percentage.
System behavior: causes of restarts or normal startup via power button?
Shutdown process: how it occurs—using the Windows shutdown tool or another method?
When you press restart in Windows, the loading icon displays "restarting," but the computer then powers off briefly—about 1 to 2 seconds—and comes back on. After this, you’ll see an American Megatrends screen indicating that your PC didn’t shut down correctly.
Consider keeping the shift key pressed during a restart from the Windows power button area. Observe whether this navigates directly to the advanced options without causing a shutdown, allowing you to explore an alternative method.
The situation is quite erratic, as it restarts multiple times normally before shutting down and then coming back on again.
Shut down the device, remove power and open the enclosure.
Remove dust and debris from inside.
Check that all connectors, cards, RAM, jumpers, and case parts are securely positioned. Adjust and reinsert as needed to confirm everything is in place.
Examine with a bright light for any damage signs: exposed wires, melted insulation, twisted or pinched cables, discolored spots, bulging components, corrosion, cracks, or loose screws.
