Windows 8.1 Blue Screen Of Death

[Timster]

Sorry you are having issues. A few things to try:

• Go into BIOS load default settings, f10 save and reboot
• Right click the start button and select "run" then type mdsched.exe in the run box and hit enter. Select the "Restart your computer and check for problems". Your computer will reboot and run a memory diagnostics using this command.
• I see no power supply listed in your specs. What is the make and wattage of your power supply?
• What are the temps on your cpu and gpu under load?
• Re-install and/or be sure you have the latest version of Directx Windows 10_Dowload_update_Install
• Disable any antivirus software while gaming to rule out conflict
• Download and run FurMark and see if system crashes while monitoring your gpu temps
  

Note that you did say your computer was crashing even before the video card upgrade correct?
