Need Help! My FX build

[Mike_22]

Hello everyone. I hope someone has some advice for me on here about my old build that went into storage and now won’t work...

 

CPU : FX (can’t remember)
MoBo : MSI 990FXA Gaming

GPU : Radeon Sapphire 480 Nitro

HDD : 2

PSU : 750 - 80+ Bronze

 

I can’t get a display and 3 people have gone through multiple things that could be the cause (20+ times) :

 

- Changed CMOs Battery

- Changed GPU slot
- Changed Wires

- Changed Ports

- Unplugged and re-plugged
- Tried HDD’s unplugged and Bios was glitchy. Only came up a total of 3 times

 

We know the GPU is alive (Few) tho the USB’s connected to the Motherboard only worked when we managed to get Windows 10 to boot. We managed to get it to boot fully once. Only the Windows HDD was plugged in and nothing since we put the second back in. We even tried to simulate the previous steps and nothing appeared.
 

Any thoughts?? I would rather not have to buy a new PC right now, tho I do plan to in the future...
