Hi again, sorry for the delay, I've been at school!
If you are overclocking your system, please return all overclocked components to their stock speeds. If the BSOD's are found not to be caused by the overclock, you can re-overclock the components once we have finished the diagnostics
Recommendations
I have noticed that you do not have an anti-virus product installed on your PC. Please install
Microsoft Security Essentials and scan your PC. Then install and scan your computer with
Malwarebytes' Anti-Malware. DO NOT START THE FREE TRIAL. This will remove any viruses you may have caught.
