It needs a new CMOs battery to replace the old one. Then try clear CMOs by motherboard jumper.
slow POST (the power on firmware test before Dell logo appears on screen) can be due to corruption of CMOs or a failing hdd firmware. If still slow try remove hdd and check if post speeds up suddenly. If yes replace hdd
