Alienware 17 - Possible GFX/LCD Issue

Hey, I've had quite a lot of trouble with my laptop the past few days. After applying some profiles in Intel XTU, i was unable to get the laptop to boot, after resetting the cmos I was able to get it to boot into windows again, but only a few hours as the gpu fan wasn't spinning and the graphics card shat itself. I was constantly getting 8 beeps from the laptop regardless of whether the gpu was in or out and whether the lcd was connected or not. I had just finished doing the oven reflow trick on my graphics card but now I'm getting power to the laptop but nothing is happening, on an external monitor I'm able to get it to display a black screen at 1080p 60hz but after a few seconds it goes away and comes back again. Without the LCD connected I'm able to get it to beep 8 times again which makes me think that the gpu may be working but due to me flashing a different vbios I think it may be unable to drive the 120hz screen in my laptop. Does anyone have any suggestions on what I can do in this situation? I have a friend bringing over an identical laptop in a couple of weeks to try out my card in there, but other than that I'm kinda lost on what I can do. Any suggestions would be amazing, thanks in advance.
Specs are,
Intel 4900MQ
GTX 780m
32GB Ram
120hz 3D LCD

 

Did you use eVGA Percision

 

No didn't use that at all. MSI Afterburner is all I ever used for GFX Overclocking.
