Hi! So the other day my laptop just black screened randomly, and since then I haven't been able to boot as it just goes to a black screen after the bios screen. I have tried removing the bios battery to reset it, done a power drain, reseating the ram, tried to reinstall windows from a USB but during the setup part way through it black screens. Any idea if this is fixable, or would you say my laptop is dead? Everything on the laptop seems to work fine when I'm using the bios screen but when I try go any further than that I can't. I ran diagnostics through the bios too and it black screens when it gets to "Testing Processor in progress". Also by black screen I mean the screen is still on, but is only showing a black backlight. The screen itself works.

Any help would be greatly appreciated, thanks!

(also it's a Alienware 17 R4, it originally flashed a code that showed a bios problem and nothing else)
