A chip fell out of the main chassis. Where did it come from?
This is a memory chip. If he fell off the motherboard, the host must have been violently hit by external forces! Now it will fall off the chassis. Maybe the master helped you repair the computer and forgot to put it back or take it out. This article may be flawed. Don't take it out and continue using the computer. And keep this well, and find a friend to help you put it back when you are free. Of course, you can also compare whether it can be loaded according to the gap position between the PIN code and the memory stick. After successful loading, the hardware will be automatically tested, and the system may ask to enter the BIOS for setting, saving and restarting. good
