If the memory causes a blue screen, crash, restart, or constant beeping alarms, follow these troubleshooting steps. If it fails, it's determined to be incompatible. a. Memory is not properly inserted, or the gold finger is oxidized. Use an eraser to clean the memory's gold finger, reinsert it, or try a different slot. b. The memory slot is dusty or oxidized. Clean it with a brush and cleaning solution (if water is unavailable, just brush it clean). c. The memory is incompatible; try a different memory module. d.
