Solved: BSOD Frequently on WIN 7

Hi guys,

I am running WIN7 Ultimate 32 bit on a ASUS A42JE.

How it all started
The other day while I was installing Windows Movie Maker from Microsoft, the whole thing restarted and then after i am back to windows, everything was super laggy. I triend opening photoshop and chrome at the same time, I checked task manager and it shows my 2 G ram was running on 70-80%.

Steps I took
I then decided to reformat it with the same OS, formated the HDD through the installer then installed the same OS.

How the problem continue persisting.
Now it is lighting fast but the problem is, it has given me 3 BSOD after reformatting in a period of 12 hours. I realise it occurs when i try to run two things at the same time. For Example, watch a WMV Movie file and installing photoshop at the same time, Watch a fb video while burning a cd/transferring file.

What is the problem?

How do I solve it?

Thanks.

Here is the code i saved from the last BSOD
