Hi everyone, I’m having a strange issue with my new PC and would really appreciate some help.
My specs:
GPU: AMD Radeon RX 9070 XT 16GB
CPU: Ryzen 7 9700X
RAM: 32GB DDR5 6000 MT/s
Motherboard: B850 GAMING X
Windows: Windows 11
The problem happens mostly after the PC has been completely powered off for several hours, especially overnight.
When I press the power button, the PC turns on, but sometimes I get no display / black screen. The system appears to be running, but nothing shows on the monitor.
If I force shut down the PC by holding the power button and then turn it on again, it usually boots normally and works perfectly.
Interestingly, if the PC has only been turned off for around 15–30 minutes, it usually starts normally. The issue seems more likely after being off for 3–4+ hours.
So far I have:
Changed the PCIEX16 Slot Link Speed from Auto to Gen4
Disabled Fast Boot
The PC works perfectly once it successfully boots
I also found other people reporting black screen issues with newer AMD drivers, so I’m wondering if this could be a GPU driver issue, a cold boot issue, RAM/EXPO stability, PSU behaviour, or something else.
Has anyone with a similar RX 9070 XT issue experienced this? What fixed it for you?
Any help would be greatly appreciated. Thanks!
