The computer isn't functioning properly.
The computer isn't functioning properly.
The system struggles to start with two RAM sticks enabled, often failing the kernel security check. On my new motherboard, it boots normally with one stick but shows errors. Artifacts appear during boot, and the GPU disappears from Task Manager even when the graphics card is present. After restarting a few times, everything works smoothly. Performance drops under stress—games run fine, but heavy tasks cause crashes or slowdowns. The GPU shows minor physical damage, though it hasn’t overheated. It operates at 67°C before failure and behaves differently during gaming. Any suggestions for troubleshooting?
