Upgraded my Graphics Card, computer no longer works? Help please!

Hello everyone! I received a Radeon R9 270x for Christmas this year, but when I plug it into my computer, my computer will not work.

I had an AMD Radeon 5700 HD Series before I received my new one, so I assumed because it was the same brand I would not need to uninstall my drivers, is this correct?

I am a bit afraid to uninstall the dirvers, because I am worried that if I do, and the new GPU does not work, I will no longer be able to have my computer operate properly.

Upon putting the new GPU into my computer, it would not operate properly. Everything turns on, fans go, and the lights on the motherboard turn on, yet the keyboard, mouse, and display do not.
However, if I put the old GPU in my computer, everything operates as it is supposed to.

I assumed this was because my PSU was only a 460w, and the GPU required a 500w. So naturally, I purchased a new Power Supply. However, after installing the new PSU, I still get the same issue. I am desperate to get this working, as I have wanted a new graphics card for a while now.

Can anyone give me any solutions/troubleshooting help?
Thanks!

Best solution

A lot of people forget but, are you connecting the 4-8 pin connectors to your Graphics Card?

also are you settings boot from pci-e and not some onboard graphics in your bios settings?

Here's troubleshooting tips for no display boot.

what is your psu..?
if you have a good PSU from well known brand (antec, corsair, seasonic, fsp, etc), even 430 should be enough for your system and 270x..

make sure all power cable (6+2pin) from psu to your graphic card is plugged properly, unplug and plug once more again to make it sure..
and try to clean graphic card golden bridge with contact cleaner or pencil eraser..


if step above is not work, well, your new graphic card is faulty, just rma it..

Yeah, I have the pin connectors plugged into both ports on the GPU.
As far as the bios settings go I'm not sure. I'm not exactly savvy in this area, how can I check that?
Thanks for the reply, much appreciated!

I have the 6 pin connectors plugged into both ports yes. My PSU is 520w, which meets the recommended 500w for the card.
If the graphics card is faulty, I will just return it as it is under warranty from the store it was purchased it from.

My old one was a cooler master, but it was 460w. The new one is a Dynex, which I know sucks, but I wanted to see if it was the power source.

I just updated the BIOS due to suggestion from multiple people. It still does not work. Is it possible that the card is dead?

man..
actually your coolermaster is a bad psu, but that bad thing is still better than dynex....

your dynex 520 actually is a 420 watt psu, but have peak power 520w...



peak power is psu ability to deliver maximum power (in your case, 520) for a few seconds..but only deliver 420w for continuous power..
well, that's mean you actually downgrade your psu..:D 

back to the topic..that's your graphic card faulty, just rma it and get the new one..:)

Just went out and got another one of the GPU's, it still doesn't work. I don't know what to do anymore. Do any of you have suggestions?

I have tried absolutely everything. I have come to the conclusion that it is my motherboard.
Thank you all for your help. It is greatly appreciated.
