Hello,
I have tried all the solutions available online to correct this problem of constant BSOD when playing games and really need some help.
I just brought a new graphics card Asus R7 260x and used the ati autodetect toold to install the latest driver for it.
I have attached DM log collector file below.

Any help would be appreciated.

First and foremost you need to update Windows to Service Pack 1 via Windows Updates.

You need to do that to keep Windows up to date with critical updates. It needs doing before any debugging is done.

You haven't performed the update.

You won't be able to perform the either as your copy of Windows is counterfeit. You have a Lenovo PID on a retail ASUS motherboard.

Counterfeit installations such as yours can contain heavily modified code that causes the installation to behave in unexpected ways. Analysing BSODs and determining their causes on these sorts of installations is completely unreliable. For this reason, most analysts won't attempt it.

My recommendation is to install a genuine copy of Windows 7. This will minimise the problems you are experiencing and make subsequent diagnosis of BSODs far more reliable. Once you are running a genuine Windows 7 installation, and if you are still experiencing BSODs, we will be happy to help you solve them.
