Normally, when I raise a support issue, some one will give a specific fix for me and after executing the same, the problem would go off. Here, I think, the problem is of too technical I suppose. I have already sent the diagnostic data and performed memtest and hdd test. Again, i got a bsod on other errors.
So, I simply copied the required files from c: and then formatted the drive and reinstalled the OS. I performed sfc /scannow and now i do not have any integrity issues.
SO, this topic may be closed as resolved.
thanks gary for your help.
