help me, /g/, you're my only hope

I have windows 7

process: explorer.exe keeps crashing

I try to click the desktop, explorer window, or bottom start bar thingy and it gives me massage: "windows explorer has crashed. 1. check for your solution 2. close 3 wait for program to respond"

after a while it will respond if i wait, but problem repeats soon after, often immediately after ward
same if i close the program; explorer.exe will restart and crash a moment latter.

here's the problem details for 'windows explorer has stopped working':
