[SOLVED] No video output RX 5500

[theDEHUNGERIZER]

Hello, so I bought a brand new RX 5500 to replace my GTX 950. With the GTX 950 I was using VGA to connect to my screen, but the RX 5500 only has HDMI output. So fine, I plugged it all in with HDMI instead. Upon powering up, the BIOS screen shows up, and then as soon as it goes to initialize/load up windows I get a black screen.

Here's what i've tried so far:

• clearing CMOS by removing the battery
• Putting old GPU back in, and connecting it to display with HDMI instead of VGA ( different problem here, I don't even get BIOS to show up, just says no input detected)
• Disabled the driver for GTX 950, shut down PC, installed the RX 5500
• Tried using onboard graphics with both VGA and HDMI connections( no input detected for either of them)
• trying to boot in safe mode with the RX 5500 installed
• updating mobo BIOS to the latest version
• All of the above methods using a different monitor

I can still get the old card to work if I plug it in using VGA.
I suspect the problem has to do with my mobo but am unsure as to what exactly it could be.

CPU : AMD FX 6300
GPU(current): NVIDIA Geforce GTX 950
Motherboard: Asus M5A78L-M/USB3 Micro ATX AM3+
Power Supply : EVGA BR 500 W 80+ Bronze Certified ATX Power Supply

GPU(new): Radeon RX 5500 XT

Try to use DDU with the GTX 950 connected with VGA since it only works that way, it’s possible that the 950 drivers is still within windows filies or even registry possibly causing the 5500xt drivers not working properly.

You said you’ve disabled the 950 and shut it down, so I assumed you didn’t fully uninstalled the drivers from the 950.

Besides that try to reseat all your cables within you pc, if none of this work it’s possible maybe the motherboards PCIE is bad.

I’m not sure what you mean by “ plugged it all in with HDMI instead,” is it just one HDMI cable?

Not related to the topic but depending what games you’re going to play, your CPU will bottleneck your new GPU, if the motherboard is bad I suggest to upgrade your whole system, motherboard, ram, and CPU (ryzen 5, or 3).

tip: In your case revert to how your rig was set up prior to installing the new card (monitor/gpu/cables). You said you disabled the driver but it needs to be iraticated completely since you are switching from NVIDIA to AMD. Once you have familiarized yourself with how to DDU your drivers keep this in mind. You will "shut-down" your pc prior to switching your GPUs. While it is shut down you will want to flip the power switch on the back of the PSU & disconnect the power source. Then disconnect all cables going from your monitor to your GPU (950). In the reverse order install your GPU/PCIE cables/HDMI or Display Port (DP is preferred)/power cord & then you can boot into safe-mode & install your new AMD drivers.

It won't take you long to get to this step in the process, but when you get here you should follow these directions for the smoothest results. You essentially want your machine to complete a fresh re-boot to accept the new hardware. If all you do is switch a few cables here and there your machine may think the old hardware is still installed & it will fail to recognize your new components. If you have any questions feel free to ask.

I did what you suggested and did a DDU of my Nvidia driver. Still just the black screen after BIOS load. I wanted to rule out HDMi being the problem, so I tested on a different monitor with DP instead. That also did not work. This build on PCpartpicker says it is going to consume 325w. I have a 500w power supply. Could that be the issue? If not that, then I feel like the only thing left is to assume something wrong with my MOBO or faulty GPU.

At this point I do no know. It is possible the PSU is beginning to fail, but I would expect a post at least since your 950 was working fine. Does your mobo have options in the bios for the PCIE?
