An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high.  This is usually
caused by drivers using improper addresses.
If kernel debugger is available get stack backtrace.

Arg2: 0000000000000002, IRQL
Arg3: 0000000000000000, value 0 = read operation, 1 = write operation

Caused by Bitdefender, which is a known blue screen crash cause on some systems. Please remove bitdefender following the second method (bitdefender's uninstall tool) in How to uninstall BitDefender and replace with Microsoft Security Essentials - Free Antivirus for Windows to run with Windows firewall.

Post back whether this resolves your stability problems.

really???

thank you for the answer very much

its just a little irony that its bitdefender with the problem, because its the first time i actually bought a whole system security and didnt use one of the free editions, shit..
i will try mailing them

Yeah, that is bad news... Sorry. For future reference, it is usually a good idea to try the trial version of security software to make sure there are no compatibility conflicts with the system. Maybe you can get a refund?
