System running but screen is off.
Hello everyone,
Yesterday I upgraded my PC and wanted to turn it on to play games, but I didn’t see any display on the monitor. I changed from an R5 2600x to an R7 5800x3D, increased RAM from 1650MB to 3070MB and added 16GB of RAM, while keeping the 650W PSU. All lights and fans are working normally, so everything seems fine. The R7 5800x3D doesn’t have built-in graphics, which means I can’t test it without a dedicated video card. b450m s2h motherboard.
I’ve already tried several things:
- Installed the old CPU, GPU, and RAM, then restarted
- Swapped RAM sticks and cleaned the ports
- Used a different cable and switched to HDMI instead of DisplayPort
- Tested on another monitor (TV)
- Performed a CMOS reset
- Verified all cables
I believe the issue might be with the connection between the motherboard and GPU, though I can’t confirm. I’ve also looked online and on YouTube, but nothing helpful came up. I think it would be best to ask for advice from more experienced users. Thank you in advance, and I look forward to your feedback.
Update your post with complete hardware details and operating system information.
yes, the gpu was utilized. however, i had it two days prior and it functioned properly in the previous setup.
