Everyday but once a day, I get a blue screen of death. "Bad Pool Header" caused by "ntoskrnl.exe" I am a computer techie but when it comes to BSOD's, I am fairly new to these. This is the exact results from the Minidump though I will include it. " A problem has been detected and Windows has been shut down to prevent damage to your computer. The problem seems to be caused by the following file: ntoskrnl.exe BAD_POOL_HEADER If this is the first time you've seen this stop error screen, restart your computer. If this screen appears again, follow these steps: Check to make sure any new hardware or software is properly installed. If this is a new installation, ask your hardware or software manufacturer for any Windows updates you might need. If problems continue, disable or remove any newly installed hardware or software. Disable BIOS memory options such as caching or shadowing. If you need to use safe mode to remove or disable components, restart your computer, press F8 to select Advanced Startup Options, and then select Safe Mode.

It occured when I was playing "CrimeCity" on facebook and the other night it happened when I was on youtube. The first time it happened I had to copy the whole hard drive onto another or it would take it 30 minutes to load and I had no access to "My Computer". it would keep loading and loading non-stop. While I am waiting for a response, I will be googling for a solution. Thanks.
