Windows 7: BSOD after closing skype error 0x00000050

BSOD after closing skype error 0x00000050

Hi! So I Restarted my PC and since skype was one of my "start UP" programs it launched and I tried closing it. Right after I pressed "quit skype" I got a bsod saying "Page_fault_in_nonpaged_area." So I rebooted my PC and it is running fine (as of now) I am just worried since this is a newly built pc. Please help! Any help would be greatly appreciated.

Hi! thanks for the quick response! I will follow your suggestions. However, I am not sure how to "test" if the BSOD will appear again since right now my computer is fully functional again. So one of the main things that "might" be causing the BSOD is Coretemp? Thank you again sir!
