Crashing all the time

Hi, I joined this forum as it looks like a great place to obtain a ton of info about windows 7. I am always eager to learn more things, maybe soon I can wander out and explore some of the other threads in this forum. But for now I need to find out why my computer keeps crashing. Thanks in advance, here is my diagnostic file.

I am attaching another file with more info. It might be the same info, but I found the bsod posting instructions and generated this other file.
-Windows 7 ultimate x86 (XP was original)
-768MB ram
-about 7 yrs old

I know I am way short on ram, but I have been running great for about 6 mos with the aero feature disabled.
I am noticing an error about an unknown driver, and it seems drivers can be a big part of the bsod. Christmas I got a new micro sd card (Kingston 4GB). Like always it installed necessary drivers the first time plugged in. A few days later the card became corrupt somehow and could be recognized on any computer or phone for that matter. This, I am now realizing, is when my computer started crashing frequently (10-15 times a day). Could this driver be the problem? If so how do I solve it?
Sorry for rambling, thanks again.

EDIT- After further searching it seems my hardware does not support windows 7 (correct me if I'm wrong). But it was running very nicely for about 6 mos.
