Hello,
So I have a Dell XPS 8300 from 2011. Recently I have been feeling the age of its ATI Radeon HD 5670 GPU, and I decided it was time for an upgrade. The original PSU was only 385W so I needed to upgrade that as well. I ended up purchasing a Gigabyte Radeon R7 260x GPU (the 1GB version) and a Cooler Master Elite V2 550W PSU. They arrived today, and after installation I booted up the computer to find that no video was coming out of my new card and pressing the power button again would instantly shut down the computer, so I knew something was wrong. I put the 5670 back in and it booted up fine, the new PSU worked perfectly. I reinstalled the drivers for the 260x and tried it - no luck. I switched out the straight 6-pin power plug from the PSU to a Molex to 6 pin adapter from the PSU Molex connections - no luck. I don't quite know what else to do, there is only one PCI-E x16 slot and I know it works. I'm not sure if the slots are PCI-E 2.0 or 2.1 or 3.0 but it shouldn't matter since it is backwards compatible (I do know the card is 3.0).
If anyone might be able to help with something I would really appreciate it. I can also provide pictures if needed.
Thanks
