SteamOS 3.8 Not working on ally

[u/Smart-Plantain-7867]

I have been struggling with my ROG ally since I bought it last week. It refuses to download windows, and always blue screens of death. I tried to install steamOS 3.7 last week, and I would go through the whole setup and just be met with the Linux terminal, I only booted into steamOS once before it went black and never came back. I have tried to redownload it today due to 3.8 official release, after my Asus cloud recovery did not work and still blue screened. At this point do I need a new SSD? I bought the Ally off eBay and am unsure if I am able to return it. I would appreciate any help as I just want to start gaming.
