The front facing speakers are the feature for me.

I often offer HWinfo, try it running the sensors only when given the option to choose. http://www.hwinfo.com/download.php

We need the dump files to have any sense of what happened, look for them in the minidump folder. C:\Windows\minidump. Copy them to a different directory, zip and upload the file.

Your friend can use driver sweeper to remove any trace of the "bad" driver after he uninstalls it from the device manager then apply the "good" driver instead. This time it should stick. http://www.guru3d.com/content_page/guru3d_driver_sweeper.html

This is most common when the BIOS setting responsible for the SATA Mode has been changed after the fact (after Windows has been installed). Switch between IDE and AHCI modes it should boot when one of those are set. Now if the setting was set to RAID it's a different story and a real pickle. Let me know .

This should suffice. http://windows.microsoft.com/en-us/windows/security-essentials-download

Anything overclocked?

I see Avast causing issues, please remove it using this Removal Tool. Also make sure that you are using the latest drivers for your GPU. lmvm atikmdagstart end module namefffff880`072c0000 fffff880`07cdb000 atikmdag T (no symbols) Loaded symbol image file: atikmdag.sys Image path: \SystemRoot\system32\DRIVERS\atikmdag.sys Image name: atikmdag.sys Timestamp: >Mon Jun 11 19:59:31 2012< Keep updating.

Dropbox is fine with me .

Dump files? C:\Windows\minidump. Copy the content of that folder to the desktop, zip it then upload here.

Good as long as you have access to the dump files upload them! C:\Windows\minidump

You're welcome, keep updating.

That is why I said what you can do in while booting.

Hi I went through the dump files and they are all similar.

I see a fair bunch of outdated drivers that can be the cause but if I have to guess I'll blame McAfee personal firewall for these bug checks. The way we can use the PC to help us find the offending driver is by using Driver Verifier. http://www.sevenforums.com/tutorials/101379-driver-verifier-enable-disable.html make sure you read the instructions thoroughly ! DV is designed to bug check the machine and it takes up a fair bit of system resources to don't be alarmed as the laptop might be sluggish. Bug check the machine a couple of time then post the new dumps.
