Several Different BSOD Errors - Short Time Period

I'll cut to the chase - my computer is crashing, a lot. It seems to do it mostly when I am either 1) allowing it to idle and do nothing for more than a few seconds, or 2) performing medial tasks like writing in Word or something like that.

All of my info is attached in a zipped file.

I'm specifically focused on the three most recent crashes (Codes 3b, 24, and 1e) . There should be a lot more in there because my system seems to bug-check if I leave it idle for more than 20-30 seconds, but my computer wasn't creating .dmp files until I ran chkdsk with both options selected.

Let me know if you need any further info. Any help would be greatly appreciated.
