Windows 10: Problems after updates, laptop freezes

On January 13, I received 2 updates: January 12, 2021-KB4598242, respectively windows malicious software removal tool x64 - v5.85 KB890830.After that, my laptop has moments when it freezes and no longer responds to any commands.In order to be able to reuse the laptop, I have to close it from the on / off button and restart it.After a period of use a few minutes or hours - varies I suffer the same thing.I would not want to reinstall windows from 0 because I have quite important files on it.And before I think about hardware issues, I have to rule out the possibility of a software issue especially since it happened after the respective updates.

Laptop Freezing Problem

For the past week I've been trying to figure out what could be causing my laptop to freeze. I have an HP Pavilion Dv6z 7000 with an A10-4600m, 7730m, and upgraded the ram from 6GB to 8GB back in January. The laptop is running Windows 8 Pro.

What happens is that I'll start up the laptop, and sometimes it'll freeze while logging me in, or after I've logged in. It's random when it happens. I could go an hour without trouble, or it could freeze as soon as I log in. If I happen to have the backlit keyboard on, it'll flicker just before it freezes. Before the freezing started, I had problems where the wifi would not be detected by the system, or the battery would not be detected.

I ran memtest86+ on the original ram the laptop came with and the new ram, and both sets passed. I ran the system diagnostics that hp has and passed all the tests. I tried refreshing Windows 8, and for a short while it would work until I restarted the computer. I've tried resetting Windows 8 with the same problem, and I've tried a clean install and still ran into the same problem.

I don't think it's heat, because coretemp shows that the cpu is nowhere near dangerous temperatures. I haven't found a program that will let me see the motherboard temps, so I can't comment on that. I also have the laptop on a Cooler Master U3.

What do you think it could be?

 

Laptop problem: Black vertical "sidebar" [Update]

I will try that... do you think I have complete access to replace the monitor cable without dismantling the laptop from step 1? *Eek!
Tbh it's a bit scary.
