Presario SR1930NX Continous Beeps

[computer.repair]

Hello all,

I am working on this presario machine.As soon as I start the machine it gives me continous long beeps. 
The machine has an inbuilt graphics card. 
I tried testing both the memory modules but still same beeping behaviour. 
Then I disconnected all IDE devices and Hard drive. With only one memory stick I tested the machine but same issue.

Any suggestions.

Thanks in advance.
