Once you know what program it is, go ahead and uninstall it. Didn't solve the problem. I have tried booting into safe mode, however it gets stuck at loading CLASSPNP.SYS. I'm sure this is well meant, but how can you do anything in Device Manager if you are stuck in a boot loop? http://ksresource.net/windows-7/windows-7-ultimate-64-bit-bsod-even-in-safe-mode.html
For me it was like 5-10 minutes. If you find that Windows is not hanging anymore, then you can be 100% sure that it's a problem with a third-party program or service. If the problem comes back, you know that the problem item is in that list of checked items. This may allow you to boot from the CD/DVD and therefore run the Startup Repair tools like memory diagnostic.
Hi.... Nor sure if having the battery out or if it was cabling. After correctly seating it, it booted fine. The location of the file is C:\Windows\system32\classpnp.sys.
