Scenario 3: “My laptop keeps crashing when I watch YouTube videos or play games. It simply freezes, then a blue screen shows up”

I have faced this error, it was quite frustrating, while watching video computer use to freeze, and then eventually lead to BSOD(Blue screen of death). Later it use to tell me that windows is recovering from an unexpected shut down.

Are you familiar with this error, Right?


Malware led BSOD

There are two things that cause this type of issue:

  1. You may have potential incompatibility issue between your software and/or hardware.
  2. Or it is malware issue

If you suspect technical problem, it may lead to this:

Are programs running in your computer in conflict? Are there any junk registry keys which have not been removed that led to system crash?

Junk registry keys are pieces of data information that has been left after uninstalling several programs from your computer. They don’t take any appreciable space than few bytes on hard drive however a single error in registry value may lead to severe impacton your computer functionality.

How to fix this:

You can use Registry Editor (Regedit.exe) that can be opened from cortana search or try typing in Run box, however this it can have daunting consequences if you accidently delete some required registry key.

My personal recommendation is to go for a cleaning session with an expert tech to help you make changes in registry. Or you can also use program like cc cleaner which is free(Two versions of this tool have been compromised by malicious actors however ccleaner is safe now)

First of all, Install CCcleaner program, click the Registry icon(as seen in image below.), you can select the items you want to delete, then Scan for issues and a list of potential issues will be shown. After that review the list and then click fix selected issues to fix Registry issues.

  • For malware infection: Run a complete scan of your computer with a good antivurus program. If you want to use which antivirus is best you can always research online about them, however our personal favourates have been mcafee, Norton power eraser and trojan remover It is always a good idea to rely on another layer of security on top of antivirus already installed in your computer. Better ti proactively fight against online threats and block them.

This behavior can occur if the free disk space on your computer has dropped below the low disk space notification threshold associated with the Disk Cleanup utility.
