Explorer.exe crashes when opening certain applications, err 0xc0000005

Hi,

Can someone help me out? Explorer.exe crashes when I play the games DOTA 2 and Victoria II.

And sometimes, when I'm at the desktop, explorer.exe crashes for no reason at all.

I've included an event log below if it helps.

Code:
