My desk top will NOT work with mp4 or avi files

[BOB4]

  My desk top is about 6 or 7 years old.I am running a --ATI Radeon HD 4800 Series [Display adapter]. When I click on an Mp4 that is on the computer it will run. When I click on an MP$ on the UBS  the machine shut down with a blue screen. This happens with AVI or MP$ from the UBS drive. Even if I copy to desk top it still happens. I have tried two laptops and both files work on the two laptops. How can I get the desk top to open these files?

Download the following:

https://www.filehorse.com/download-klite-codec-pack/

 

See if it will run with those - I does't look like a codec problem but it might be.

 

Is it just media files that error? It may be worth trying a different USB stick or reformatting your current one.
