PC generates random green screens.
PC generates random green screens.
PC details: Asrock b450 steel legend Ryzen 5 5500 RX7600XT, 16 GB G.SKIL Trident Z 32 GB Deepcool LS720, MSI MAG 650W PSU. Recently I upgraded to a new GPU—Gigabyte RX7600xt (switching from RX6600). Initially the transition was fine, I installed the latest drivers and updated everything. At first I barely played any titles, just a short Fortnite session and about an hour in Red Dead Redemption 2 until my new GPU started making loud fan noises. I adjusted the fan curves and hoped it would help, but it only partially resolved the issue. Then my system began freezing, displaying strange green screens and odd lines on the screen (attachments included). I researched various fixes—removing XMP settings, reinstalling drivers with DDU, re-seating the GPU, disconnecting power cables, and reinserting it. At first I suspected a power supply problem since the 650W PSU should provide enough power. However, the green screens appeared randomly, even while browsing. Eventually I stopped playing games to investigate further. I tried running DBZ Kakarot at the same settings as other titles; it crashed after about an hour, showing a standard AMD error but no green screen or reboot. This led me to suspect driver issues from AMD. Next, I played Fortnite—it froze and again displayed a green screen before restarting. Eventually I powered off the PC, reset it later during the day, and worked for around four hours without any green screens. It remained stable until it randomly green screened once more after rebooting. After removing the PSU, switching the power cable back in, it refused to show. I tried a different HDMI port, but no improvement. When I reinstalled my old GPU, it worked perfectly. I even played Fortnite for an hour without any issues. Anyone with tips would be appreciated—this situation has been really stressful lately. It feels like the new GPU isn’t working as expected. Maybe the original model still has problems? XD
There are various methods to assess your VRAM. None of them match the reliability of data center cards. Be careful about making quick conclusions about the issue.
It might be a minor power problem, though unlikely. You should be okay with a 600W unit; I’d recommend at least 850W for peace of mind. Do you have any spare PSUs or a local shop where you can request a test? I recall someone here had a similar situation—his GPU fans spiked to 100% unexpectedly after a Windows update. Did he update to Windows 11 before this happened? You might want to try removing the latest Windows version and see if it resolves the issue. (Back up your data before attempting any removal.) A better approach would be a clean install on another drive, even if it takes longer. Just install drivers and a game for stress testing. Avoid updating Windows unless necessary. If the problem persists after a clean install, consider sending the GPU back to support for an RMA. Alternatively, you could try installing Linux to see if it works there.
Thanks for the guidance. I have a spare PC ready to test. After returning from university, I’m planning to try it out again, but there’s still no display. I’ll use the second one. If that doesn’t work, I’ll send the card for replacement since I bought it just a week ago.
I'll wait until the second rig is working before responding. It's really frustrating, especially since I rely on my PC for both my studies and work.
I can verify it's the GPU. It seems the images didn't show clearly, but using my old GPU confirmed the second PC works, while the new one didn’t display anything and the VGA light stayed on constantly. I’ll send the card for RMA. Thanks again for your help!
