Nowadays computers do not have floppy drives. Generally, a CD-ROM drive or a hard disk is required to boot the computer when starting the system. There are also some motherboards that will automatically protect themselves due to lack of power supply when there is no power, and may not be able to boot. First of all, I suggest you replace the motherboard battery. Then according to the problem you described, it should be caused by the memory module not making good contact and the motherboard not detecting the memory module. It is recommended to unplug the memory module and wipe the contact points. Extended information The motherboard battery is used to record the time of the computer system, that is, to maintain the accuracy of the system clock. When the power is insufficient, the time will return to the factory date, and to record the hardware information used during startup, that is, to maintain the CMOS BIOS. information. If the motherboard battery is out of power and the computer is not turned on for two days, the system time will not be accurate after starting up and will return to the time when the motherboard was produced. When the battery is insufficient, the system time will slow down.
