Windows 7: Random Crashes resurfaced. No BSOD

Some of the guys who helped me way back might remember my post here

Apparently, its happening again. (My solution to the thread above was reformatting)

Like before, the whole screen locks up and nothing responds, the Num Lock works for about 5 seconds before it jams up as well.



It has happened while the computer was idle, as well as when I've been gaming.

Virus scans and Malware scans with MSE, MBAM and Spybot S&D reports nothing suspicious.

Windows is fully updated and Display driver is of version 260.89

It has always happened when my internet was connected (Never tried without net).

Does it somehow have anything to do with Network settings? Cause once I changed my public sharing settings to allow me to connect to my Win XP pc using this tut Share Files and Printers between Windows 7 and XP - How-To Geek

EDIT: I've just ran sfc /scannow like i did the last time... Turns out this time there were some corrupt files. They were fixed successfully. I'll report if i start crashing again.

Please post the information from here even if you're not having BSOD's: http://www.sevenforums.com/crashes-d...tructions.html
