Bootup Problem of Dell PE6650

perhaps your hardware isnt correct setup in BIOS or some of harddrive not working correct

it means your hard disk is not detected by system, check all connections of hard disk, if problem remains check with another working hard disk

once in the setup (F2 at boot) turn on Caps Lock, NumLock and Scroll Lock (all 3 keyboard lights on)
Press ALT + E (system should beep once) Press ALT + F (System should beep once) Press ALT + B (System should reboot and re-detect drives)

Press the F8 key during boot up.

Did you experience a power event? Go to BIOS (F2), and make sure that RAID is Enabled. If RAID got turned off (power event, BIOS reset), then it will give you that message. If RAID is already enabled, then you may need to repair your operating system. If something else happened (drive failures, drives removed, etc.), then the array may be completely gone. Call Data Recovery services if it is critical you retreive the data.

you need to go to cmos or bios setup, set all the date and time and proper boot setting there save and exit, it is a cmos or bios failure that causes these problems try replacing the cmos battery if the message still continues

Dear Don't worry, there are some options you will have to press or check one by one "F1or F2 or F8 or F10 or F12 or del. Now, You can enter in CMOS setup.

Try getting BIOS access by pressing F2. Then try rebooting.
