click on your bios maker and hey presto these your fault

Short rapid beeps?

Did not say mobo manufacturer or how many beeps..

Easy to assume it's your video card or memory at this point.

See the following thread for bios beep codes list

Without knowing how many beeps etc. it could be a number of problems, the most likely 3 are as follows

Try reseating the following:
CPU
RAM
Monitor VGA cable

those are the three most common that won't let your machine start at all.

The continuous series of beeps should indicate that there is an issue with the power supply. If your PS is not 'large' enough, you can not support two HDD's, CD, DVD, etc. Disconnect one at a time...begin with the second HDD, if this is your situation. Have you added an after-market fan?
