Okay,
What I'd like you to try is booting into Safe Mode with Networking, it'll look a little weird, but use that mode, and go to YT, and watch the video that caused your machine to crash.
If you can't remember which one it was just pick a high quality one, and see if you get a BSOD.
If you do not then you should reinstall your video card software/drivers.
Once done, restart in regular mode, try the YT video, and see if that takes care of it.
If you need help with that on the dell site or if you have the OEM disk let me know, and I'll try to walk you through.
I can stick around for a little while, but it is getting late for me.
