i have a hp envy 17t-j000, and it's connected to an external monitor due to broken laptop screen. it's a intel inside core i5 and has nvidia geforce. so when i connected my laptop to an external monitor, i thought why not make it a dual external monitor display. and i did, been using it for over 6+months now, and all of a sudden i'm experiencing the "Black Screen of Death". fixed it the first couple of times it happened, and decided not to turn off my laptop again. 2weeks went bye and there was a power outage at my house. as soon as the power came back, i tried turning on my laptop, it turns on but with a black screen, no light on the screen nothing nothing. i turn it off and turned it back on again. the same result. i checked the Ram, replaced the Ram, the same result. the laptop comes on but displays nothing. you can here the fan spinning and all that but there no display on the main screen. so my question is this: did i distroy the graphics card by running dual display on the laptop or the Ram slots "cause i have 2 4gb ram installed" are bad or something else?
