Qosmio x300 intermittent hang-ups

Question

I have a new Qosmio x300 and have been having the same issue as described here:
http://forums.computers.toshiba-europe.com/forums/thread.jspa?threadID=42058&tstart=0
The computer locks up and if sound was playing, it loops very rapidly for about 5 seconds.
It happens as well when the computer is idling,
If video is running, it freezes for the duration of the hang-up, also with a rapid audio loop, then after 5 seconds the sound resumes, but the video "smears" for another 5 seconds.
If a game is running, the game hangs up with a rapid audio loop. In worst case, the game also crashes after the hang-up has passed.
I have not been able to localize what has been causing these hang-ups, as they are not listed in the event manager at all.
I will also not purchase any additional third party software to track the source of the hang-ups, as I have already paid 1300 Euros for this notebook. If it has defect parts, I will be taking it back to the store I purchased it at for a full refund.
I would however, prefer to find what is causing the issue so that a solution can be found not only for myself, but all users who have a Qosmio with the same symptoms.
*edit* I have begun to check the hard drive with the HD Tune free version. After 25 minutes, the Temperature went from 42 degrees Celcius to 56 degrees. I do expect the drive to heat up during an intensive disc and error-check, but I thought I would include all information that could be relevant to finding the solution here as well.
The HD Check completed successfully with no indication that the Hard Drives have any problems. The heat also returned to 42 degrees after the test completed.

I have the same problem with my Qosmio X300 (PQX32E-04H02WGR). Anytime I'm playing games there is a blackscreen and a tuneloop.
I wrote a email to the toshiba-service in germany and they told me to make a new installation of windows, to install the new bios 2.1 and the new beta driver from nvidia. Even this all did not solve the problem.
So I ring up the german hotline and they told me that there is nothing more to do and that they don't know that problem. They sayed I could try playing the games in a reduced resolution and perhaps this could solve the problem!!!??? Yes... I buy a very expensive gamer-notebook to play with it in a reduced resolution - nice idear.
After I told them that I think it could be an overheating-problem they want to get the notebook to find it out on my own risk (I have to pay a service-charge if it is no overheating problem).
We will see...
