Issues with new GPU on gateway DX4870-UB318

[Golden_1]

I don't know if my firmware being old is the issue but I've been through 2 (used) graphics cards so far with.

The first faulty GPU was a PowerColor TurboDuo AMD Radeon R9 290 4GB GDDR5 512bit OC and it would black screen when i tried to play games 7 to 30 min in; Sometimes the card stopped with and error sound but usually with a sound boom after a color flash on the screen.

The second GPU was a EVGA GeForce GTX 780 Graphics Card 3GB GDDR5 and it never showed a display, the signal was found, but nothing but a black screen would show.

I am currently using Gtx 750 OC with a CX750M PSU (brought for the other cards) and there is 0 problems with that setup.

My Full rig (excluding the currently used graphics card and psu)

I want to know if it is the PC, used Gpu's, my Bios or something else entirely that's keeping from getting another stable GPU.

The CX series PSU uses poor capacitors, it is fine for your gtx750, but is not good for the high end GPU, like the r9 290 or gtx780. Get the PSU is at least tier 1 or 2. here is the list: http://www.tomshardware.com/forum/id-2547993/psu-tier-list.html
