keeps restarting wont start

David,

What I’m reading is that you tried to reset “something” but instead of resetting it just shut down. Then when turning it back on, you’re getting a boot-loop. I’m going to assume in this answer that you’re talking about a PC running Windows 10 as this is the most common PC in the world right now.

Accidental Shutdown:

This can be caused by holding the power button down for more than 5 full seconds. Most motherboards power off when the power button is held down for 5+ full seconds. This could also be caused by a jammed power button, which could also be resetting your system. Though most likely the system was hard-locked when you went to reset it, and since it didn’t reset right away, you held the power button down until it powered off.

Boot-Loop:

Restart loops usually occur when Windows is trying to self-update and is interrupted. Though other corruption can be the cause as well. Anything from a bad peripheral (bad video-card, bad third party card, etc.). In Windows 10 you can press CTRL-F8 to get the diagnostic menu. In there are various options like restoring to a previous snapshot to reinstalling the OS completely to running the system in safe-mode. My first recommendation is to try Safe Mode. If your PC doesn’t start in safemode, then something critical is damaged/corrupted. Let me know if Safe Mode works for you and we can go from there.
