Unusual display fragments and system failures following the GPU upgrade.
Unusual display fragments and system failures following the GPU upgrade.
CPU and components performed well overall. The system stayed stable without crashes during normal use. Upgraded graphics from an older model to the 6950 XT, followed by driver installations and BIOS adjustments. Occasional screen glitches occurred but no persistent errors were found. The monitor and PSU functioned properly. Multiple reboots and troubleshooting steps didn’t resolve recurring issues. It seems hardware installation was correct, though software or power settings might have contributed to instability. Consider checking for firmware updates, ensuring proper cooling, and verifying driver compatibility.
It seems like the problem might be related to software. Here are some steps to try: 1. Clear the CMOS as the BIOS might still expect a Nvidia GPU. 2. Boot from a USB drive—it could be a Windows installer or Linux, doesn’t matter much. The aim is for the computer to start and show something. 3. If USB booting works, you likely need to reset and reinstall Windows. Even with DDU, some services might not have transferred properly from Nvidia to your new AMD GPU. Hope this helps.
You cleared the CMOS and managed to start your PC, but it kept crashing. After resetting Windows, you also faced a crash. Then you changed the BIOS settings following the CMOS reset and still encountered issues. What could be causing this?
I discarded the surplus cables after assembling my PC a few years back since I noticed the cable issues in the 30 series. I assumed I’d need replacements before upgrading my GPU, so I purchased this specific cable that matched my PSU on the Corsair site before the upgrade. It came with a 2-pack, and I’m currently using one of those.
Consider using two distinct cables from your PSU to the GPU. One should support 250W or more, plus 75W for PCIe slots totaling 325W. You might have a model with higher TDP, possibly up to 350W, so ensure your GPU receives adequate power. Even if this isn't the perfect fix, it's still recommended to use separate cables for cards exceeding 300W.
A crash during BIOS settings suggests a hardware issue. Do you have an extra power supply? It’s unlikely you’re drawing excessive power in BIOS, but a bad PSU could cause problems like this. Also, have you verified all connections, cables, and properly seated your RAM and CPU?
Managed to fix it. The system is now stable and the monitor behaved as expected after the initial setup where compatibility settings were detected and HDR plus proper refresh rate applied. Followed your advice to use both cables. Initially assumed the Merc (XFX Speedster MERC319 RX 6950XT Black) wasn’t power-hungry, so I rated my cables at 600W instead of 300. Appreciate the assistance!
I accepted your diagnosis. Successfully booted into safe mode with no issues. Rechecked the event viewer and noticed errors related to Kernel Power 41, suspecting a power issue. Inspected hardware and discovered a loose cable on the PSU. Reinstalled all cables connected to the PSU and motherboard, confirming no further loose connections. Installed the additional PCIe cable and the BABIDYBOOPY STABLE BUILD SCOOPITY. Appreciate your assistance!
