Hi, have you change your CMOS battery? If not, I would suggest you to change it. Remove the old CMOS battery for about 30 seconds, place the new CMOS battery. Do not plug your computer yet, press the power button to release the stored voltage from your computer's Motherboard.

Now turn on your computer. If it is still beeps, remove your RAM, clean the gold plated bottom of your RAM with a rubber eraser. Then, fix it again into your memory slot.

You should be able to boot you Computer now. Hope that helps.
Thank you

Wow, what a great idea, considering you have repeated my fix.

A beeping computer means there is a hardware failure. If you haven't yet, change out the BIOS battery, and restore the BIOS defaults. Then ry to boot. If you still have beeps, then a piece of hardware is failing!
