It would be helpful to get a picture of a BSOD the next time you get one. To do this, you need to set your system up so that it doesn't automatically reboot when a BSOD happens.
Right click on Computer, then click Properties
In the left hand pane, double click Advanced System Settings
Under Startup and Recovery, click Settings
Under System Failure, uncheck "Automatically Restart"
Under "Write debugging information", click on the arrow and choose "Small memory dump"
Click OK to save off your settings.
A screenshot is attached on how the Advanced Settings are should look after your modifications
Mini dumps and pictures or notes from a BSOD are very helpful in debugging any problems you may have.
