Whats wrong with my PC

Sounds like you might have installed a bad driver?

Can you boot into safe mode?

yes i can once i boot into safe mode what should i do

Can refer to this:

http://search.microsoft.com/Results.aspx?qsc0=0&q=PAGE_FAULT_IN_NONPAGED_AREA&mkt=en-US&FORM=QBME1&l=1

All sorts of faults can cause this error. Zip your last 3 *.dmp files, and upload them using the Link below:

Also test your RAM using memtest86+, and run the HD diagnostic tool of your HD manufacturer. You'll find both of them on the UBCD:

how do i zip the lat 3.dmp files and upload them to the website?

You zip them with a tool like 7zip (you can google for that), and then just go to the Link I posted, login with your ee account, and then under the experts tab you have an option to upload files.

where are the .dmp files located

I'm not sure where windows 7 has saves those dumps, but you should be able to find out by looking doing the equivalent for the following (which is for XP):

right click "My Computer", select "Properties", the "Advanced" tab, the "Startup and recovery" section on "Settings", and there under "System failure" you should see where the minidumps are written to. On XP this usually is C:\Windows\Minidumps\

Under this setting you can also select the types of dumps you want. minidumps are normally sufficient, so I'd make sure you select that, and if you don't have any yet let the system crash another 3 times, which will create those dumps.

hello i have uploaded the .dmp files in a winRAR

What am i supposed to do now?

do i wait till some1 has a look at the files

agree ..... AVG could cause of this blue screen / error as well ..... especially the internet security .... try uninstall it and see .....
