Windows 10: Windows 11 boot failure and blue screen errors

Hi,starting from three weeks ago, my laptop began acting weird. For some reason the boot manager sometimes fails, but if I restart then everything is back to normal. I've also run into several blue screen issues. One recorded stop code is WHEA_UNCORRECTABLE_ERROR and just now I got another one 0xc000021a. I took my laptop to a local pc store for help, and they checked my laptop. No problem at all with any of my hardware. Given this, I'm really wondering: What could be causing these boot issues and blue screens?Thank you in advance for any help.
