Windows 7 - Random BSOD then restart

Hi,

My system has been running fine for a good year until yestarday. I was on the internet at the time and just browsing sites then all a sudden the display went black and a BSOD appeared to which the system then restarted itself. When Windows 7 booted back up I had a message telling me the computer had recovered from an unexpected shutdown with some information tagged to it. I dont have that information although I have used a program to create some files which I have added below.
Also I scanned my hard drive for trojans and found one infection which I deleted. The problem still persisted so I have formatted my hd and done a clean install of Windows.
After the clean install it`s still happening. Since yestarday the PC has randomly restarted itself about five times. Any info on this would be super. Thanks.

There were no .dmp files ... navigate to c:/windows/minidump and zip up any .dmp files and attach them to your next post...

Oh! sorry. I did navigate to the minidump folder but there are no files there ?
