Windows 7: Bsod bad_pool_caller

10 Feb 2013   #1

Win 7 64 Bit
Bsod bad_pool_caller

Hello! I want to thank you ahead of time for trying to help me out.

We started having BSOD's a few days ago, which started with a IRQL_NOT_LESS_Or_EQUAL. I couldn't figure it out, so I did a clean install of Windows.

Tonight we had another BSOD, this time a BAD_POOL_CALLER.

I've attached the required files.

Hopefully someone can help me out!
