Your device appears to have some unusual behavior.
I'm facing several persistent issues that have become more frequent over time. First, when attempting to power on the computer, I often need to adjust and reposition the CPU, GPU, and RAM, clear the CMOS, etc., before it even starts. This usually happens every time I shut it down. (Even after clearing it, it tends to stay on with debug lights on the DRAM, GPU, and CPU—only when I lightly tap the CPU cooler does it boot.)
Second, I recently acquired a used RX 580 from a friend. I use three monitors—two HDMI and one DVI—and everything works fine except for the DVI monitor, which only functions when connected to the HDMI TV. The HDMI display works regardless, though I can't explain why. I've tried installing my old GPU and reinstalling drivers, but nothing seems to resolve the problem.
Third, I play racing games like Forza Horizon 4 on my old GPU, which always worked before. Now it doesn't function with the RX 580. I'm struggling to figure out what's going wrong with all these setups.
The RX 580 typically uses one HDMI port and one DVI connector, which is standard for dual connectivity. If your monitors support DisplayPort, you might want to invest in a suitable adapter or cable. Regarding the power issue, unplugging the PSU briefly could reset internal protections that require full discharge—disconnecting the power cable usually helps. It’s possible a BIOS or chipset problem is interfering with the 5V standby mode, which keeps the motherboard powered. Check the BIOS settings and disable low-power states if needed. For Fortnite, consult community forums for reset procedures or safe mode options, then adjust settings accordingly. If the game still misidentifies your GPU, try connecting it to a different PCIe slot (like X16) on the motherboard, which uses a different chipset and may support NVIDIA cards directly. Adjusting in-game settings via the NVIDIA control panel or through save files can also resolve persistent issues.
It might be your cooling system failing, causing overheating and preventing the system from booting. If you didn’t install a CPU cooler and tried booting without one, switching to the built-in cooler could help. If the issue continues, run diagnostics like memtest and thoroughly test each RAM module individually. Check one stick at a time and compare results. If nothing changes, the problem likely lies with the motherboard. Try placing your CPU in another computer for stress testing (e.g., Intel Burner) to see if it runs. If tests pass, the motherboard is probably faulty. If not, replace the cooler or component accordingly. Ensure any cleaning fluid used during testing is non-conductive.
I'll give it a shot. I had them for a while, but the drivers were behaving strangely.
