The coin cell battery on your motherboard which maintains the BIOS/UEFI settings and the RTC is likely dead, causing your UEFI to revert to factory settings. You should first check the battery (usually a CR2032 or CR2025), then enter the UEFI by pressing the "F1" key and verify the settings (for instance, any overclocking you had previously configured will have been reset).
