Explorer keeps crashing with ntdll.dll, verifier.dll, msvcrt.dll and combase.dll errors

Question

Hi all,
I just bought my laptop a few weeks ago. Initially explorer only crashed (with the ntdll.dll error) when I had a lot of folders open, or when I was transferring stuff. But now I cannot open any folders at all without it crashing with the verifier.dll error.
This doesn't happen in safe mode.

This is the event log for one of the errors. I have also uploaded two dump files after explorer crashed onto my skydrive:
https://skydrive.live.com/?cid=05A8CC170A7688F5&id=5A8CC170A7688F5!105
Can anyone please help me? I have found many similar threads but I'm not sure which program is causing the crashes for me. Thanks very much!

Hi again,
Sigh. Explorer crashed on me again. I was using iTunes when this happened (not sure if relevant), I wasn't transferring files, and had 4 explorer folders open. 
Would you please download explorer.exe.3432 from my skydrive and analyse it for me? Thank you so much for your help. 
Here's the event log for my most recent crash: mscordacwks.dll error?
