What does this mean and how do I fix it?

So my computer just randomly crashed so I ran Who Crashed and it came up with this

Crash Dump Analysis

First and foremost, You need to update your drivers.

 

Also boot into your Windows Disk, hit repair, Advanced Options, Command Prompt

OR

In windows, open CMD as an Administrator

 

And do a system file check (type in sfc /SCANNOW)

Also recommend to give the system a good clean up (malware, programs, etc)

If that has come only once and you haven't had any issues before and after it, then just ignore it. I had that also last week. Or week before. No problems after it. It just means that drivers have crashed.
