If your getting BSODs then here is something you can try to further diagnose what exactly is causing the problem.
First if you havent done so already you need to make it so the computer doesnt restart after a BSOD.
Here are the steps to do this:
-Rightclick on My Computer and goto properties
-then goto the Advanced tab and hit Settings under Startup and Recovery
-now uncheck the box to Automatically restart
-Hit OK to make sure this change gets saved
This will keep your PC from rebooting so you can fully read the BSOD.
Now you should enable the Verifier so that the BSODs show more detail as to the cause.
Here are the steps to do this:
-Open up the command prompt; Start → Run → type cmd and hit enter
-Now type this exactly to enabe it:
Verifier /flags 9 /all
-now you should restart your computer, you may notice it will take a little longer and things might run a little slower while this is enabled.
-Go ahead and fire up Bitcomet.
-This time when you get a BSOD it should give you more information as to what the cause is.
-After you read it you will need to hold the power button down to turn off the computer.
-Turn your PC on again and uninstall whatever is causing the problem or look for software updates for whatever is causing the problem.
After you fix whats really causing the problem you will want to disable the Verifier to speed things up again.
Go into the command prompt again and type this exactly to disable it:
Verifier /reset
If you are able to figure out what was causing the problem please post here exactly what .dll or whatever else was causing the problem since this could be helpful to the developer.
