I have owned my G74SX for about 2+ years now(don't remember the exact date). I was getting all adventurous and decided to rid the rear exhaust vents of super-clogged dust. I just removed the back panel, and used a brush to clear any little dust off the HDDs and the ram sticks and used a vaccum pipe to suck as well as blow of dust from the vents. Finished it, closed the lid, lappy started off fine, I was installing ccleaner when all of a sudden the OS froze, no response from trackpad or the keypad, so I did a hard shutdown by holding down the power button. When I powered it on again, I can hear the fans running slightly, the caps-lock and num-lock leds stay lighted, but there is no display and it remains like that.
I went the extra-mile and unscrewed the whole thing after following some quick youtube guides, cleared off more dust blobs, and fit back the screws neatly(Stupid thing to do on retrospection). Now it does not even power up, power button does nothing, even the charging led-indicator stays off, no activity whatsoever, and I'm at my wits end, how do I fix it and revert it to normal state?
I'm thinking that maybe some power connectors or display connectors got loosened up, but otherwise I'm at my wits end, help please...
