Fixing Blue Screen Errors

Many BSOD problems are caused by driver, registry, or memory issues. Have you updated your drivers recently? I know there are a lot of posts on Google that agree with this line of thought.

I don't know if this will apply to your problem, but here's one poster's suggestion as uploading the symptoms of your BSOD to Sevens Forum so that the experts here can help you diagnose the problem:

To upload the BSOD symptoms to Seven Forums, upload the contents of your "\Windows\Minidump" folder. The procedure: Copy the contents of \Windows\Minidump to another (temporary) location somewhere on your system. Zip up the copy. Attach the ZIP archive to your post using the "paperclip" (file attachments) button.

To ensure minidumps are enabled: Go to Start. In the Search Box type: sysdm.cpl, press Enter.
Under the Advanced tab, click on the Startup and the Recovery Settings button.
Ensure that Automatically restart is UNchecked.
Under the ‘Write Debugging Information’ header select Small memory dump (256 Kb) in the dropdown box (the 256kb varies).
Ensure that the Small Dump Directory is listed as %systemroot%\Minidump.
Click OK + reboot if changes have been made.
