Avi, I've had an HP laptop and I still have it, but that because I am still trying to sell it.
But it's like passing a bomb, you know.
My laptop had dedicated video card and it was fast/good, but it lasted a little more than an year..
the solder joints were cracked. And my laptop wasn't smoking...
HP laptops have a chronic failure over BGA, requiring a soldering rework on it.
In Brazil it cost me 200$, something like 90 USD.
Not sure if that's your problem... As far as I researched and talked to people, it's a very common problem with HP.
You could try selling it, if it's your interest (recommended btw), go for somebody who fix laptops or someone who can work on the BGA solder.
Not sure if its because of overheating or planned obsolescence... but anyway never buy an HP again.
