Fixing boot-up crashes on Biostar B650MT for Mass Effect
Every time I hit start, the screen would go black at 40% loading with a memory overflow error, which was incredibly stressful. The old BIOS on the Biostar B650MT had terrible support for newer instruction sets, causing a 0x0000005 access violation when calling AVX instructions. I tried running it in compatibility mode, but that was a total nightmare—it actually crashed more often, sometimes every ten minutes. I decided to risk flashing the latest Beta BIOS, switched memory from Auto to a manual 5200MHz, and disabled the redundant legacy serial ports in Device Manager. The red error logs in Event Viewer finally vanished, and the game actually loads now. I almost bricked the board when a power flicker hit at 80% during the flash, but a hard reset triggered the auto-recovery. Idle temps are 42-48℃ and load hits 72-78℃. After three clean reboots, the input response feels tight and responsive.
