I believe we are looking at some memory misalignment boundary errors, which may have caused by invalid machine operation code.

Run Driver Verifier to scan for any corrupted drivers which may be causing problems, this program works by running various stress tests on drivers, in order to produce a BSOD which will locate the driver; run for least 24 hours:

Alright I did what you just told me to do, and it told me I had to restart my computer in order for it to run. Now my computer gets to the windows boot logo and gives me a bsod saying a driver is trying to access memory that has already been freed. I tried running the windows startup repair but it's not working.

Boot into Safe Mode, and then disable Driver Verifier. The instructions are in the link wrapped around the Information box. Please post the dump files afterwards.

My 2 cents try thee scanners too

(download from bleeping computer)

Personally I would try Hitman Pro too Home - SurfRight

There are more rootkit removers from here too I have used GMER and Sophos and Dr Web Cureit
Best Free Rootkit Scanner and Remover the GMER is a heavy duty thing I find and leave it to last if I have to.

Use the SF Diagnostic tool from this post. Blue Screen of Death (BSOD) Posting Instructions

The tool, Windbg, they use here is more comprehensive than Blue Screen Viewer.

As you have said, unfortunately, the Driver Verifier dump files are not there. I would suggest running Driver Verifier again.
