Windows 7 kernel_data_inpage_error BSOD at random

Did a little googling on the Teredo thing and there's a couple of solutions in this page here:
http://answers.microsoft.com/en-us/...s-device/757db042-c91e-464c-b963-c1f442fdf925

I followed some of those instructions and the Teredo thing is just gone from device manager altogether, and the crashes are still happening. Not really sure what happened there.

Also, I wasn't quite sure what to run with Seatools, but I clicked through the scans that were compatible with the hard drive and it passed them.

Try checking the Event viewer and see if it mentions anything relating to the crashes.
