Blue Screen upon Internet Connection

Hello,
I'm here because I'm feeling a bit desperate; my problem is as follows:

I can't connect to the internet through my Freebox (both Wi-Fi and Ethernet), as well as through the university Wi-Fi. It shows a blue screen marked with multi-colored pixels. I can roughly read: dumping physical memory 0%=>100%

However, I can connect to Freewifi and Wifirst.

There's something quite funny, which is that I can connect to my Freebox in safe mode with network support.

My equipment:
-Easynote LJ75
-Windows 7 64 bits
-Network card: Atheros AR5B93 Wireless Network Adapter
(if you need more, just ask me; I don't really know what else to provide.)

With my IT teacher, we reinstalled the network card drivers and updated the BIOS.

I have the impression that it's due to Service Pack 1, which may have had issues during installation. My teacher tried to uninstall and reinstall it manually, but upon rebooting after the uninstallation on the screen before the session choice, there are the percentages of "update installation," and after reaching 100%, we saw FAILURE and cancellation of modifications.
I ran antivirus scans with ESET Smart Security and ESET Smart Security Online, Malware Anti-Malware, and found nothing.

Thank you

Configuration: Windows 7 / Firefox 15.0.1
