Random Freeze Black/blue screens After OS recovery

[elise.mutchler]

I need help. Mid December I had my laptop’s fan replaced by a tech store guy. I had to take it back multiple times since he forgot to reattach the finger print scanner the first time and the next time the WiFi did not work, which he did not actually fix but gave me an external WiFi adapter which worked for 2-3 weeks then stopped. I have not had time to take it back. Since Jan 9 I started my pc and it let me use it for a while before the screen flickered and went black. I have also had this happen where it went bsod after. On restart it did not let me start windows. I have performed minimized image recovery, factory reset ,changed bios ahci settings ,messed with the bios system clock, removed the external adapter and disabled windows updates suspecting the Spectre fix but had limited success. Every once in a while after the os recovery options repeatedly fail, They randomly succeed on the 5/6th try and I have been able to use my computer 2/3 days at a time to do anything I normally do, game or watch videos. I cannot point to a trigger, but when this happens it sometimes does not allow me to even access the hp recovery tools or system repair at all. I have run memory checks and malware bytes which showed nothing. Any advice would be so appreciated, I love my pc,

First test with one RAM stick at a time. Try a clean Windows setup on a different hard drive. That is a bit of an older laptop. can be a hard drive failure, maybe motherboard. Have you been checking temps in the system since the repair?
