Opinions needed on problem with brand new notebook

I just purchased an HP Pavilion dv7-1232nr Entertainment Notebook PC. The specs for this machine are at:

My problem is that when I took the machine out of the box and turned it on it started to make a noise (similar to the noise made when you save to a floppy disk). After a few seconds it stopped and everything seemed OK. I then went through the start up procedure, registering, etc. for the notebook.

Once it finished that I decided to make a set of recovery disks before uninstalling some of the trial versions of software. While going through the recovery disks steps I got an error message saying I couldn't do this because my machine does not have anything to burn CD's with (which it is supposed to).

To make a long story short after 2.5 hours on the phone with HP support and me taking out & resetting the CD drive the computer finally recognized it was there. During this process tech support had me turn the machine off 12-15 times by holding the power button down.

When the CD drive was finally recognized HP support had me recover the system to the original factory settings. After I did that everything seemed OK, I plugged in to my DSL internet connection and Windows downloaded 24 updates and installed them.

The computer said it needed to be restarted which I did. But when it finally booted up all I got was a dark gray (almost black screen) with nothing. Not even the cursor. (This happened at least 5 times when I was on the phone with tech support also.)

The only way I had to turn it off was by pressing the power button once again (this was the only time I did it on my own without being promted by tech support).

I would like to know if you think it would be a good idea to continue with tech support to try to get the problem fixed, or if you think I may have more serious problems and should return the notebook.

Thanks in advance for any input on this problem.
