Our recommendation to narrow this issue down is following a clean installation of the Operating System using the latest drivers from our website:
Follow the critical driver installation order outlined as follows:
1) Fresh Operating System Installation. This means formatting and partitioning the hard drive.
2) Latest Service Pack or Patch
3) Install the Intel Chipset Software Installation Utility (INF Utility)
4) Install all other drivers
5) Latest Microsoft* DirectX* Version
6) Any third-party software you would like to install
How do you know it's the Intel drivers causing the freeze?
There is a known bug that causes Win7 x64 to randomly freeze.
See the link below for the hotfix. The hotfix is an interim solution that may or may not resolve your issue. The fix still needs more work and will likely be released as an update once they get the bugs worked out.
Microsoft has announced a hotfix for stability (system lockup or freezing) issues in the Windows Filtering Platform implemented in Windows Vista, Win7 & Windows 2008 Server.
Well i suggest that you do few things, assuming you have a good Antivirus with virus definition up to date:
1- Delete temporary Internet files & cookies
2- Login into Safe Mode and run full system scan for viruses
3- If nothing found, schedule a drive error check for the next logon
4- If the problem persist, i suggest you save your files, format your PC and install a fresh copy of Windows, then download an install the latest drivers for your Motherboard from the Intel website
Finally i got the answer....There were two options in motherboard (under Power option) intel virtualization technology & convert processor state from C1 to C or something like that...i didnt remembered actually....but all i did is i just turned off those 2 options & boom....it worked...it never hanged again...:):)>:)
But thank you so much guys... I cannot explain you how happy i am
