koolkat77 thank you so much for replying. .My brother kept saying it might be crashed because he had connected his smartphone galaxy grand without drivers and it crashed. It has been 2 weeks no bsod and now when I started the pc and just opened the browser chrome for surfing bsod started. I am still using paid Quick heal anti virus it will expire next year. I am posting both one with SF Diagnostic Tool - Using for Troubleshooting and other one is just dump file.Please tell me if it is the antivirus program that has caused I will try to check with the company

Hi Gautam S .

Do you have the Product key and installation file for your paid Antivirus ? If so for testing purposes you could uninstall it and reinstall the product after you have fixed your BSOD issue .

First of all, go it http://www.sevenforums.com/bsod-help-support/280818-blue-screen-problem.html, close it by marking it as solved. Otherwise we will merge these two threads. You are not supposed to create multiple threads for a same problem. Create a new thread only when the earlier issue is over.

The present crash dump indicates to Quick Heal AntiVirus as the crashing element.

Uninstall QuickHeal. Use Microsoft Security Essentials as your antivirus with windows inbuilt firewall, and free MBAM as the on demand scanner.
Download, install and update those, and then run full system scans with both of them, one by one.

It's a mater of a trade off. Either you rip the benefit of the money you paid to QuickHeal and suffer from BSODs, or you forget the money, use the free antivirus suggested twice and have a crsh free computer. I just can say that I would never invest my hard earned money on QuickHeal.

Next, Run SFC /SCANNOW Command - System File Checker

If you get more BSODs, post it following the Blue Screen of Death (BSOD) Posting Instructions.

Any more information is needed there? I guess no.

If you want to be free of BSODs, get red of QuickHeal. If you want to use QuickHeal...... accept the BSODs as normal :sarc:

And dont start any further thread by being disappointed at my reply .... you get the same reply everywhere.

I see the same thing Archie has posted.

In addition, it may be necessary that you update your Windows 7 to SP1. Numerous critical updates and bug fixes were made to many Windows' drivers. It could be that your new AV is not compatible with the old drivers. Further attempts to debug an old Windows version are useless.
