Sorry to hear that, mate, but it seems like something went wrong and sadly enough since it's not youtube, they will not send a team of highly trained monkeys to fix it (hope someone will get the joke).

On the more serious note, I'd suggest you find a place where you could ask how much repairing could cost and then decide for yourself whether or not you should buy a new laptop. It does matter what you have right now, but since you posted this in older G's, then I would suggest going new if you have money for it.

Another thing is that you scratched something on the MOBO, or GPU started to overheat because of something. Are the fans working? Because you said you've cleaned them, maybe now they're stuck or something (just a wild guess, but what can you know).

Either way, best of luck.

Haven't been able to post in a while @_@ but yeah my left fan kind of looks like it slows down when I turn it on but my fans go full force I watch it go and the display never works external monitor or not...just keeps spinning and roaring never really booting up posting to bios or anything I bought a new mobo on ebay and replaced my old one and still same issue : /

here is my private youtube video of the issue the sound of the fans that is...

also forgot to mention that my ribbon connector the power one to mobo burnt up when the laptop wouldn't turn off with me holding the power button before it started to stink idk if holding the button made it do this or not...
