HP Envy 17 Display :: Notebook Screen Flickering When Click Something Or Open A Folder

It flickers when i click something or open a folder. It also goes crazy when i put on a video.
 
Things i've done: 
 
Updated drivers.
''Hold power button'' method.
 
Clues i have:
 
1. I remember back when i just got the laptop, it would always flicker in the exact same way when a charger was plugged in that was too weak (power out let too low message) and changing the charger always fixed it.
 
Now i still have the same charger (i have 3 hp and 1 dell chargers at home that fit my laptop) and none of them seems to be ''enough'' (60w x2 65w x1 and 120w x1).
 
 2. Another funny thing is that when i uninstalled my Ati Radeon HD5850 drivers completely, there was no flickering, but obviously, i need to have that as i use this laptop strictly for games) 
 
3. The screen refresh rate is 60hz and not possible to change,.
 
4. There is NO flickering on an external screen (tried two tvs, both didn't clicker a bit)
 
5. You might say it's a hardware problem, but i actually somehow got it to work without the flickering earlier tonight and stayed up all night playing and it didn't cause me any issues. It was working great.
 
6. Occasionally the PC will freeze (could that be a battery problem? since i currently am not using one as both mine are broken and i'm waiting for a new one to ship)
 
7. I have had 2 blue screens of death recently. One while installing ATI drivers and other i don't remember.
