Hi [NAME] thank you for sharing update.  The CPU and GPU are permanently soldered onto the motherboard and the Dell fix is to replace the motherboard.

However, there is the $100 Dell Laptop Repair | Dell Repair | Laptop Repair | Notebook Service Center (parts-people.com). 
Hi, Here's the problem I have with the Laptop: When I boot my Alienware Laptop I see the post display information with the Alienware logo, then I see the Windows (or Linux when I install Linux) boot logo but as soon as one of the OS is done booting I get a black screen. Windows or Linux is up and running in the background as I can do key commands and hear the according beeps and sounds. I can also do a clean shutdown with hot keys and hear the shutdown chime but no display. If I boot in the Bios I have a display.If I boot in Windows or Linux I get the post boot display with logos, information..etc But once in any OS, Black screen.If I boot in Windows Safe mode I have a display. I suspect when the Laptop boots, it's using the integrated Intel GPU to display the post, Bios..etc. But as soon as an OS boots up and uses the Geforce GPU, it goes black. My next step would of been to replace the GPU thermal paste but it's a total shot in the dark. Any help \ hints appreciated.Thanks
15 R4, no display
