My PC has started acting up, and both of my monitors are glitching, so I suspect a hardware problem. I'm unsure whether it makes more sense to troubleshoot and upgrade the system or buy a completely new PC, especially with RAM prices being high and new systems being expensive. By upgrading, I mean replacing the CPU and GPU. Current components: Ryzen 7 5800X, Radeon RX 6750 XT, Gigabyte B550 Gaming X V2 motherboard, 32GB Corsair RAM, and a 1TB Kingston SSD. The power supply and exact symptoms haven't been listed yet.

That hardware is still capable, so a CPU and GPU upgrade would probably be poor value until you identify the fault. Check whether the glitching follows the monitor or cable, test the monitors with another device if possible, and run a memory test. If the RX 6750 XT shows artifacts in BIOS or in another computer, it may be failing. Please also provide the PSU brand, wattage, and age, since an unstable power supply can cause display problems.
I wouldn’t replace or upgrade the whole system yet. Since both monitors are affected, start with the simple checks: try different DisplayPort or HDMI cables, connect one monitor at a time, test different ports on the graphics card, and see whether the problem also appears in the BIOS. Also check temperatures and make sure the GPU is seated properly. The power supply model and age are important details too.
A clean graphics-driver reinstall using DDU is worth trying, but do it in Safe Mode and install a known-stable AMD driver afterward. If the monitors started turning off immediately after the reinstall, test an older driver and check Windows display settings. If the issue happens before Windows loads, it’s more likely to be hardware, cabling, or power related than a driver problem.
I already ran DDU and reinstalled and updated the drivers, but afterward one of the monitors turned off. I’ll try testing different cables, ports, and drivers to narrow it down.
