BSOD at login screen, also had many BSODs randomly in the past

I'm just getting around to doing this now because I just returned from a long vacation. A few days prior to leaving, my computer started blue screening at the login screen before I could finish entering my password. In the past, I've had many instances of the screen freezing, the sound freezing completely for a few seconds and then going silent, and becoming completely unresponsive. It wasn't fixed without a restart, and it was only a matter of time before it would happen again, be it minutes or days. The problems I've had with this rig are always unpredictable. AMD everything... obviously a bad choice.

Something I think is important to mention is that I have SoftXpand 2011 installed on my computer, which makes it automatically boot into a multi-workstation mode the first time you turn it on. You can disable and make the computer a single workstation as usual by logging in, disabling it, and restarting. This could be the problem, I guess. I also cannot access my external drive while in dual workstation mode. It always says access denied or something.

I don't know what else I should include in this... hopefully I provided enough information for someone to help me out here! Thanks.

EDIT: the attachment was created in safe mode when I turned the computer on for the first time in 2 weeks, then restarted it into normal mode, and then got the blue screen again with "DRIVER_IRQL_NOT_LESS_OR_EQUAL"

my specs are on my profile
