BugCheck C1, {b9726f68, b9726b40, cd0094, 23}

Probably caused by : memory_corruption ( nt!MiCheckSpecialPoolSlop+6e )
The specifics of this bugcheck can be found on my blog here - BSODTutorials: Debugging Stop 0xC1 - Sloppy Bytes and Special Pool

Okay, the dump file doesn't reveal a faulty driver, however, a driver has caused some form of memory corruption. The later dump file revealed Avast as the last running process, this doesn't essentially mean that Avast is causing problems, but it could be a indication since I've seen Avast frequently cause problems in the past.

I'll recommend the removal of avast with avast! Removal Tool, at least for testing purposes.

Install and perform full scans with:

Remember to install the free version of Malwarebytes not the free trail; untick the free trial box during installation. MSE is the most lightweight and compatible with the Windows 7 operating system

You can also view this thread for a complete free and lightweight security protection combination:The dump file doesn't reveal much information at all unfortunately, the memory contents seem to be pretty corrupt, since most the useful extensions don't work.

The trap frame indicates a divide error, which is another sign of drivers being problematic.

Long time reboot after a BSOD
When i reboot my pc after a bsod it sometimes doesn't boot up right away. I need to turn it off and on again or just wait a couple of minutes. Plus it takes a long time to boot up. I guess it is a hardware problem and would apreciate if someone told me which component can cause this.
