Windows 10: My laptop Boots but Glitches and Restarts soon after!

My laptop began to die very quickly and soon after it wasn't able to turn on without the charger being plugged in.I've gotten some blue screens over the past month. The frequent mini blue screen asking me to check my BIOS, the CMOS checkum is invalid.I just recently had a blue screen saying the critical process died and another with 0xc000021a.Despite all this my laptop still boots and I could try and use it fine but after a less than three minutes it glitches out, freezes, and restarts itself.I know I can't save it. I'm tight on money so there's no repairing this. But I would like to at least

:)

 

laptop doesnt boot automatically

This is what happened.

1. Did a repair install and later disabled hibertnate in CMD.
2. Enabled legacy option ROM in BIOS.
3. After a few times startup ( i used the system in such mode for 5 days), changed boot option back to default.
4. Vola!! It boots automatically to win10 without any keypress. Tested it with many starts to confirm the same.
5. Re-enabled hibernate option using CMD and later selected Fast Startup.
6. System booted normally, without the need for any keypress.

I do not know exactly whether such steps resolved the problem or what else happened, hence cannot suggest above steps.

Many thanks to all members who helped to troubleshoot problems.

glitching screen and glitching videos

Hello,

Recently my laptop screen started to freckle\glitch while playing videos either on the internet or on my laptop so I followed steps suggested as to uninstall and re-install the graphics update however, it happened again not so long after I did that (1 day later) and I fixed the display and so it stopped but the videos appear to be glitched? like I could see the RGB (there is a color stroke that appears ONLY while watching videos and I tried to take a screenshot and while trying to trim the photo I found it looking normal so it's only via videos

I'm using HP ENVY Laptop - DESKTOP -LUQEG7V
