This must be some kind of thrid part software issue. PO itself on a healthy computer shoulf not cause any blue screen.

Try to figure out if you have any antivirus/registry/spyware/firewall software that is working on the lowest layer and in some way is blocking PO.

There is one known crash (which possibly also could cause blue screen). This occurs when playing on PokerStars and PO is not installed correctly (again due to antivirus/firewall software that simply refuse to let PO save files and run them on your computer).

Do you play in PokerStars? If you do, you can check one thing: after you have started PokerStars but before you start PO (you must not have started PO at all after restart of the computer) bring up the Task Manager (press Ctrl+SHIFT+Esc keys) look in the Process list; can you see any process called javaw.exe here? If not you have a problem with one or more of your security software.
