overheating and strange smell on Dv7 notebook

[DarlaDarDar]

I have noticed that my system seems to be overheating and has a very peculiar smell. I actually thought there was something wrong with our furnace, so i kept going in the basement to check it.  However, it turns out to be my notebook.  I have used spurts of air to clean the vents, I have vacuumed out the little vent holes, but this thing keeps going into overdrive on the fan.  It is constantly blowing and the notebook is very warm, if not hot, to the touch.  I also noticed that my system gets very sluggish at this point.  So I have to constantly shut it down.  Is there something I can do, or am not doing that would correct this? 

This smell actually causes me to cough and my throat gets irritated.  I really need to find the source and correct this.  I use my system A LOT.

Thanks for your help, and here are my specifications on my system:

HP Pavilion Dv7 Intel core i7 2.20 GHz

Win 7 64 bit

Radeon HD

Similar issue on a dv6t, not sure if yours has this issue, might be worth checking

wow! this seems to be exactly what my problem is.  However, I already called it in and am waiting for them to send my box for shipment. Hmmmm I am so scared to open this thing and it is still under warranty.  I think that might void my warranty.  Also should I mark this thread as solved, because this is surely what I am experiencing?

You can mark it solved, you can always start another thread later if needed.

Be sure to back up your personal files before you ship it, HP sometimes reinstalls the OS without backug up your files, they do this without informing you also.
