Laptop is playing BSOD roulette; every crash has a new surprise..

Hello everyone,

My system has never been very stable (broken fans at purchase, two dead HDD's, main videocard dying) but for the last few days I've been having tons of crashes (varying from a few minutes to 6 hours apart) and I'm having a hard time figuring out how to fix them. I'm pretty sure the problem is driver related, though for the life of me I can't figure out which device is causing it since they're all 'updated to the newest drivers' according to windows..

Could it have anything to do with undervoltage due to the fact that my laptop is housing a dead Nvidia 650M? I've disabled the drivers for it but I wonder if it's still able to **** up my system even while idle. Heat might also be a cause since the fan side tends to get hotter then the surface of the sun..

Big thanks to anyone who is able to help me out.

Hope it's okay if I bump this, it's been 24 hours so it's seems reasonable enough to me. Had three more crashes today ..on occasion the BSOD itself will crash with screen artifacts and everything. Pretty scary considering I already have a dead gfx card and I certainly don't want my last one to die.

It's been two days with no replies so here's another bump. Still hope someone can point me in the right direction on what I should do.
