Windows 7: Appcrash

Hi, I formatted my computer and installed some basic stuff:
Chrome
Security Essentials
Magic Disc
AMD ATI Display Drivers
Live Essentials 2011

Then went on about installing games etc.
Next thing I see is chrome saying application not starting correctly, then Messenger with an appcrash message and like a deck a cards it all just start falling (read as giving appcrash).



Here is a game appcrash

I have done a "Diagonistic" boot and I didn't get any error. Only service not from Microsoft is AMD External Events Utility.

Thanks.

See this: SFC /SCANNOW Command - System File Checker

C:\Users\Mike>sfc /scannow

Beginning system scan. This process will take some time.

Beginning verification phase of system scan.
Verification 100% complete.

Windows Resource Protection did not find any integrity violations.

That's the result of the sfc /scannow command.

ok this problem has been solved, it was due to the Ati Tray Tools that installed an unsigned driver.

Thank you anyways
