Worst tech support ever.

I have always had nothing but great tech support from dell but recently i feel like they have screwed me. My m17x r2 stopped working so they sent me a refurb that stopped working after 5 mins, then they sent me another refurb with the same issue, so they sent me a third and this one worked for about a month, which was exactly the time i had left on my warranty. i called dell anyway and they said they would fix it for free anyway, they sent it back with a missing fan, they came and added the fan yesterday for free also, which made me happy. however my computer still isnt working. it doesnt boot into windows and now they wont help me anymore since my warranty ran out. and ive spent over a month just going back and forth with repair after repair and refurb.
idk wat to do. i just want a simple fix. everytime i boot into windows my computer blue screens. however safe mode works fine. so im thinking it could be a driver maybe? ive never had this problem before. i did a fresh windows install twice and got the latest drivers from dell's website.

 

So you're saying you did a fresh install and everything and your computer still shows you the BSOD?

Intelligent thinking would've been to extend the warranty since you had issues, that's what I would probably do in first place, but since you're here, a suggestion I could think of is to open the laptop, get to the GPUs, make sure everything is in the proper order, no screws hanging out or nothing loosened, if you got a chance, try installing a different copy of windows (maybe earlier version or another build) I still think it is internal to your laptop though.
