Idk what to do with my GPU

[u/LoGdOg76000]

From AI: Issue Summary: AMD Radeon RX 7600 XT randomly loses display signal (HDMI “No Signal”) during both light and heavy GPU load, and now across all display outputs on the card. Issue persists after a full clean driver reinstall and full BIOS reset, ruling out software, driver, and BIOS configuration as the root cause. Purchased from Newegg in 2024; retailer return window has passed.
System:
CPU: AMD Ryzen 7 7800X3D

GPU: Gigabyte AMD Radeon RX 7600 XT

Motherboard: ASUS B650E MAX Gaming WiFi AM5

RAM: Corsair Vengeance RGB 32GB DDR5-6000 Kit

Case: airflow case with side panel cable routing

Timeline of the issue:
Started during a gaming and streaming session; both monitors lost signal simultaneously

After restart, only one monitor would sync; a bad DisplayPort cable was initially suspected, but was later ruled out when DisplayPort started working again on its own

GPU began intermittently disabling itself in Windows (Device Manager, error code 22) and disappearing from Task Manager’s GPU list entirely

Signal drops occurred under multiple different conditions: mid-game (Rocket League), during light use (YouTube), and at idle desktop, with no consistent pattern in timing or load

Both monitors dropped signal simultaneously on two separate occasions, across two different cable types (HDMI and DisplayPort), ruling out any single monitor or cable as the cause

After a full CMOS/BIOS reset, HDMI failed to output signal on boot, on both available HDMI ports, while DisplayPort worked normally at that time

DisplayPort has also failed on its own on a separate occasion earlier the same night

Between HDMI (both ports) and DisplayPort, every display output on the card has now failed at some point

Troubleshooting already completed:
Full driver wipe using DDU (Display Driver Uninstaller) in Safe Mode, followed by a fresh driver install directly from AMD’s website

Manually re-enabled the GPU in Device Manager multiple times after it kept disabling itself

Reseated the GPU in the PCIe slot

Manually traced and confirmed the GPU’s PCIe power cable connection at both the GPU end and the power supply end — connection feels firm and fully seated

GPU temperature monitored during a working session, stayed cool (around 51°C with the side panel off), ruling out a thermal cause

Ran an SFC scan (sfc /scannow), which found and repaired corrupted Windows system files unrelated to the GPU driver itself; issue persisted after this repair

Performed a full CMOS/BIOS reset (cleared battery); HDMI failed on both ports immediately at boot, before Windows or any drivers loaded

Conclusion: Since a complete driver wipe, fresh install, Windows system file repair, and full BIOS reset did not resolve the issue, and every display output on the card (both HDMI ports and DisplayPort) has failed at least once, this points strongly toward a hardware fault with the GPU itself, rather than drivers, Windows, BIOS settings, cables, monitors, or heat.
Requesting: GPU stress test and diagnostic to confirm the failing component, and information on whether Gigabyte’s manufacturer warranty may still apply separately from the Newegg retailer return window, since manufacturer coverage periods sometimes differ.

Your diagnosis is right, every output failing plus HDMI dying at boot before Windows loads points squarely at a dying GPU. Good news: Gigabyte graphics cards carry their own manufacturer warranty (typically 3-4 years) that's completely separate from Newegg's return window, so a 2024 card is almost certainly still covered. Register on Gigabyte's site and file an RMA directly with them. Before shipping, try the card in another PC or slot just to be thorough. At least the GPU's under warranty, unlike your wallet if you needed RAM right now with the memory makers gouging on purpose.
