The graphics card wasn't seated properly. Which is bloody ridiculous because we reseated everything in this machine twenty thousand times. But apparently it needed a good punch to be seated properly and LO, the friggen thing is working now.
Let me just say this, I KNOW YOUR PAIN! When I first upgraded my Ram in my old build, it stopped working. I had no clue what the hell it was, spent hours trying to figure it out, only to realize I didn't have it push in all the way.
Then when I was building my new PC I ran into the exact same issue with the RAM, but I did figure it out pretty quickly thanks to my MOBOs debug system!
Fast forward to when I was installing my 3080, and I thought I had the exact same issue, that the 3080 wasn't seated properly. You know the saying fool me once, shame on you, fool me twice, shame on me, fool me three times and I may just be an idiot. Well I would be damned if I was to be fooled a third time.
So I spent hours trying to figure out why the 3080 wasn't working and I was confident that it was because it wasn't seated properly as it is a tight squeeze for the beast in my case. At my ropes end I googleD it and found out that you cant daisy chain the PCIE cables for a 3080, and that is exactly what I was doing!
I'm glad you've got your computer issues figured out! I remember you telling me about the issue you had and how you were not sure if it was the MOBO or the PSU! Who woulda thunk it would have been the Ram!
It was actually the PSU!! xD ... it was tripping and I needed to get a new one. And it was one stick of RAM too! So at the moment I am foregoing my dream of 32gb of RAM and instead have your basic 16gb. It'll do for now. I can't be bothered dealing with a warranty return for that when I need to return the entire batch just for one faulty stick. 😣 I'll just get 2 more sticks later on.
AND THEN!! Apparently ASUS motherboards are known for being a bit fiddly with graphics cards. Like, we put it into my partner's build and it worked, then popped it back into mine and it didn't. Turns out you need to literally smack it into some motherboards and mine happens to be one of them, haha! Such a pain in the arse. 🤣😂 Like, I'm annoyed at this whole thing, but I admit, it is pretty funny too. xD
This is the last time I get a CPU with no integrated graphics. If I had that, I would've been able to access the BIOS and everything and would've been able to troubleshoot a lottttt easier. ☆Big heaving sigh of annoyance☆
