Help with random blue screens on Boot Camp (0x000008e, 0x0000024).

Hi. So, recently, I've formatted my entire computer (a Macbook Pro with OS Lion) and decided to try reinstalling Windows with Boot Camp. However, I am beset by numerous blue screens. I installed the drivers, but it seems that they're still somehow causing blue screens. However, they do all seem to have something in common: the file "ntkrnlpa.exe" seems to be causing all of the problems. I also know that there's no issues with the hardware itself because someone at the Apple Store ran diagnostics and said that all the hardware was okay.

Here are the most recent dmps. Any advice would be appreciated.

Also, as an added note, the tech guy who's helping me suggested possibly updating the BIOS, but I have no idea how to do that with Boot Camp, so if I need to, please tell me how.

One last note: I already took care of the Avast thing by uninstalling Avast.

Hi there!

Seems like the dumps are pointing to Avast try to run the Avast removal tool and remove the left over files. Run SFC /Scannow to make sure all the Windows files are intact. Enable Driver Verifer Using Driver Verifier to identify issues with Drivers that will help us in pin poitning the issue.

So, I gave the computer to a couple of tech guys, and they said that it was a problem with fan drivers. They formatted and apparently installed the drivers, but I'm still getting blue screens. Here's the most recent .dmp file. Any ideas? Right now, I'm thinking that since the problems started with Lion, if I downgrade to Snow Leopard it could solve the problem. What do you think?
