PC shuts down upon connecting the second monitor (RX 580)
PC shuts down upon connecting the second monitor (RX 580)
These are my current settings: I'm using an old Lenovo ThinkStation P300 with some Lenovo Sharkbay motherboard, Intel Core i5-4570 processor, 4x4GB RAM (16GB), Sapphire Nitro+ graphics with Radeon RX 580, and 4GB of RAM. I'm running the latest drivers for the graphics card. The system is connected to an LG monitor via HDMI to VGA adapter, and I've recently replaced another LG monitor with the same adapter. When I connect it to the second HDMI port on the RX 580, everything works smoothly. However, after a short while, both screens turn off and the PC stops responding. Initially, the PC was still running but there was no video on either screen. I checked if Anydesk was open and accessed via my phone, finding an AMD error message about driver failure. I rebooted the PC, and only one screen turned on at first. My video drivers were corrupted, so I reinstalled them, but whenever I try to connect a second screen, both turn off after a while and the PC crashes completely. I've tried connecting only one screen at a time, noting that my old 1080p LG monitor works fine when connected to port 2, while the newer 768p screen works with port 1. Connecting a 1080p screen to port 2 or 768p to port 1 causes crashes after a few minutes. I don't have any DisplayPort or DVI monitors or converters available for testing other configurations right now. Despite stressing the GPU to maximum, it doesn't crash. It seems power might be an issue or there could be another problem. I've attached some photos showing the crash and driver installation attempts, but so far no success with both screens connected.
Have you considered revisiting the GPU driver update? Also, which Windows version are you currently using?
No problem: I have a TV and could connect it via HDMI, but since I’m moving to a new house, I might try later. I’ve changed adapters for my monitors and even used the new one in a laptop—everything works fine. If I connect both together, the PC runs smoothly, but when I plug them in side by side it crashes. Could be an issue with the power supply unit? It seems like it might be drawing too much current, maybe around 500W.
The problem doesn’t seem to be with the power supply since your setup appears stable under heavy use. It didn’t crash when operating at full capacity. Since both devices can be connected to your laptop, the issue likely lies with the desktop. If the problem persists even with updated drivers (and drivers are recognized), consider switching to another graphics card—perhaps you’ll need to take the device to a repair shop if none is available.
There’s no clear way to capture an error log during a crash. The issue seems to involve sudden loss of power and display, making it hard to retrieve any diagnostic information. The Event Viewer entry you found only mentions power loss without showing detailed errors.
No success either. Tested various drivers, including three different versions, but the issue persists. Also tried connecting via HDMI, which caused the crash again. The key difference from older drivers is that the PC remains operational. I can use Anydesk on my phone to access it, and AMD Windows shows a message indicating driver crashes. Restarting corrupts the drivers and prevents proper loading.
It seems the problem might be related to a driver. I’d check if booting in safe mode reveals the same issue and try enabling services one by one to identify the culprit. If I’m short on time, I’d back up my data and consider a fresh Windows installation. Should that fail, swapping components (if possible) could help isolate the cause. A local repair shop can assist by using replacement parts.
