Hi, some reasons for Blue Screens
New hardware - software installed.
Device driver - Video driver - corrupted - faulty.
Faulty Ram - Overheating - Dying hard drive, etc.
======
Update your Nvidia - AMD drivers.

======
Run a Mem Test.
http://www.memtest.org/
Scroll down to 'Download (Pre-built & ISOs)'
'Download - Pre-Compiled Bootable ISO (.zip)'
Download the ISO file then burn to a Cd.
Start the Pc using the Cd and run the memory test overnight or for at least 8 passes.
It is best to run a full scan on individual Ram sticks if you can.
Or run the test but if any errors are shown - then remove all sticks of Ram - test each Ram stick one at a time and test them in different slots.
