Inspiron5110 gives 5 repeated beeps 4 times on booting

These are called BEEP CODES. google beep codes. Your bios is telling you something is broken. normally you can find beep codes in the troubleshooting section of your PC's users guide/owners manual. If not, the beep codes are BIOS specific. If you know whych bios you have (ami, etc.) then you can usually decode the beep codes.
