Hello, I have tried all sorts of troubleshooting for the past couple of weeks and nothing has seemed to work.
Simply, my GPU (GTX 750Ti) does not work in my system, I just get a black screen on my monitor and sometimes a flashing amber light on the power button.
This lead me to believe it was a motherboard or PSU error, however my friend let me borrow his old GTX 750. I tried this in my system and it works. So my question is, is my GPU fried? or what is the underlying issue here.

PC Specs:
Dell Inspirion 3847
CPU: i3 4170
GPU: 750Ti (doesnt work), 750 (works)
RAM: 8gb DDR3
MOBO: Standard Dell MOBO
PSU: standard Dell MOBO (300w i believe)
BIOS: UEFI

Any help would be amazing, Thankyou!

Well, if it's only 2-3 years old, it should be a vairation of the ATX/ITX standard. Looking at the size and another thread, probably a Micro ATX motherboard. And it looks like any full size PSU will fit according to: https://www.dell.com/community/Desktops-General/Inspiron-3847-Power-Supply-Specifications/td-p/4468796

But see if you can borrow one, or use another PC and bridge the cables over (sit the two PCs next to each other and use the power wires from the good psu). It'll be cheaper than buying a PSU that you might not need.

The system itself is around 2-3 years old. The only problem i'm having with looking into buying a new PSU is that im not sure as to what size I need to get, considering Dell gives no indication of the form factor of the case nor PSU.
