Welcome to SF, unfungames.
First, do the following:
HOW TO FILL OUT YOUR SYSTEM SPECS
In the line at the top of
www.SevenForums.com you will see
UserCP.
That is an abbreviation for
User Control Panel.
Click on
UserCP.
In the left-hand column, under Your Profile you will see
Edit System Spec.
Click on
Edit System Spec
You can copy and paste from the output of Speccy,
Speccy - System Information - Free Download to fill out much of the info. Be sure to use the
Other Info section of your System Specs for such info as your optical drive, your wireless adapter, your speakers, etc.
When you say blue screen, is it the blue screen of death (with error messages) or just a blank blue screen.
Have you updated your video and audio
drivers?
