Hi,

I got the X51 back in 2013 and recently started using it again to play some low end PC games like World of Tanks.

Today I got a black screen and fans on full multiple times, only able to restart with a power cycle and once loading up with integrated graphics.

I'm hoping that changing the GPU to something slightly newer will fix the issue at a minimal cost as I don't want to throw money at it being an old PC.

I've got the R1 - i5 3450 with GeForce GTX 660 and 330w power supply brick.

What are my options for GPU upgrade that are confirmed to work? I know little about building PC's which is why I'm after some advice- and also the reason I purchased the x51 back in 2013 in the first place!

Any advise would be appreciated.

TIA
