A deadly case of BSOD on a gaming computer

Hello there, Sevenforum users. I've come here with lost patience. I've been having BSODs for the past 2 months, almost always during gameplay. I'm a big TF2 player, and it's a pain not being able to play for 3 minutes without a crash. I did make the mistake of deleting almost all my memory dumps in multiple disk cleanups, but there should be 2 or 3 BSODs within the zip. And also, I've been getting freezes too, lots of them. I hope you guys can help with my problems.

A little thing I forgot, here's all the error codes I've ever gotten:
3B, 1E, 7E (The most recent spree of error codes), 7F, 50, 3D, and 4A. One thing to note, 3D is that the Printer Queue is full, and I've never installed a printer.

Some basic system specs:
Windows 7, 64-bit Home Premium, which I personally installed on my built PC.
The PC itself is about 6 and a half months old, still a youngin'
I did re-install Windows 7, hoping it would fix my problem by wiping the hard drive clean, but it didn't fix it. The re-install is about 2 months old

And also, I do apologize if I didn't zip the items properly. I'm not educated in file zipping, only in file unzipping

Please reply with any additional info you need. Heck, if you need more BSOD samples, I can always make plenty more. And thanks ahead of time for all help

Speak of the devil, got another 3D on the desktop. I've got updated BSOD info now. Added another 3 samples, 2 of which are 7E and 1 is 3D

Just a bit of an update (And a bump since I didn't get much help) I found the area of most of my crashes. It's at atikmdag.sys
