So I had to turn my PC off by the power switch in the back.....

[JohnFL2119]

And now it turns on for a second, then turns off, and repeats this. I dun goofed.
Thing is, the power button has always been finicky. I have to press it multiple times, sometimes holding it down for 5 seconds, sometimes not, to get it to turn on and off.
So I got impatient this time when my PC froze and hit the power switch. I didn't think it would be a big deal.
But now I'm reading how it can really mess up your PC. I'm bringing it to Geek Squad to see if they can reset the BIOS/CMOS for me because I lack a jumper, etc.

Has anyone experienced this before? What should I expect? I'm nervous AF since this is a brand new PC.

if the computer does not boot for a free cycles it should clear CMOS on its own. how far does it get?

The cycling on and off can indicate an overheating issue or a power delivery issue (e.g. faulty PSU). Clearing the BIOS settings (i.e. clear CMOS) would be a good place to start; ensure the power cord has been removed from the power supply unit (PSU), then remove the CMOS battery and leave it out for at least 5 minutes. Then, reinsert the CMOS battery and reconnect the power cord to the PSU. Check that the I/O switch on the PSU is set to ON, then try pressing the power button on your PC.

The CMOS battery will look similar to this: https://en.wikipedia.org/wiki/Nonvolatile_BIOS_memory#/media/File:Battery-lithium-cr2032.jpg
