Black display and odd visuals following Minecraft play — Radeon HD 5670 problem
Your monitor displays strange patterns before going dark after gaming. The hardware specs look normal—Radeon HD 5670 and Athlon II X2 220. You've already checked the GPU, replaced RAM, reset BIOS, but still nothing happens. No visual or sound cues. Could be a software issue, faulty cable, or failing motherboard. Consider testing with another monitor or checking for driver updates.
Your computer may have stopped working after reseating the GPU and RAM, and resetting the BIOS. Verify the power cord connection and ensure the PSU switch is set to "1." If nothing works, reinsert the RAM, then the GPU. Consider replacing the CMOS battery, as it might be dead on older models. If you still have no luck, try using a different PSU. It’s possible your current one has failed. Good luck!
You might consider proposing a natural death explanation if artifacts were present. If there were signs of artifacts, I’d assume a black screen would follow. Based on that, I’d go with the idea that the GPU stopped working naturally.
