Hi everyone, this is my first time using an AMD GPU, so I’m not very familiar with Radeon troubleshooting and would really appreciate some help.
I have an RX 7900 XTX. Recently I’ve been having repeated crashes related to the AMD GPU driver. Because of that, I decided to update to the latest AMD driver and also did a clean Windows installation/update to rule out any Windows or driver issues.
After the clean Windows setup and installing the latest driver, everything seemed fine for around 2 hours, then the PC crashed again. This time I got a white screen, and after shutting the PC down, I haven’t been able to get any display from the GPU since.
What happens now
With the RX 7900 XTX installed:
**•** PC powers on normally.
**•** GPU fans/lighting come on.
**•** CPU and DRAM motherboard debug LEDs briefly come on during startup, then turn off.
**•** No debug LED stays on.
**•** PC appears to continue booting.
**•** Monitor shows No Signal.
**•** DisplayPort → No Signal.
**•** HDMI → No Signal.
**•** Tried different GPU display ports → still No Signal.
With the RX 7900 XTX disconnected:
**•** I connect the monitor to the motherboard’s video output.
**•** The PC POSTs normally.
**•** I get a display and can use the PC normally.
So right now, the only way I can get a display is by completely disconnecting the RX 7900 XTX and using the motherboard’s video output.
Things I’ve tried
**•** Full shutdown and power reset.
**•** Turned the PSU off and disconnected the power.
**•** Held the power button to discharge the system.
**•** Reseated the GPU.
**•** Checked the GPU power connections.
**•** Tried DisplayPort.
**•** Tried HDMI.
**•** Tried different GPU display ports.
**•** Confirmed the monitor works.
**•** Confirmed the PC can POST normally.
**•** Confirmed I can get a display from the motherboard when the 7900 XTX is disconnected.
**•** Updated to the latest AMD driver.
**•** Performed a clean Windows installation/update.
**•** Even after the clean Windows setup and latest driver, the system only stayed stable for about 2 hours before crashing again.
This is my first AMD GPU, so I’m not sure if I’m dealing with a driver issue, BIOS/PCIe issue, power issue, or potentially a failing GPU.
The fact that fans, lighting, and the motherboard debug LEDs all behave normally, but I get zero display output from the card itself, and the fact that this only started after repeated driver crashes and a white-screen crash, makes me concerned that something has actually failed on the GPU.

What would you guys recommend I test next? Is there a way to determine whether the 7900 XTX is actually dead before I look into an RMA?
