My mother board has a continuous beep tones

Hello and welcome to the forums  
Try cleaning the memory contacts and remove all modules except the first bank.
If it didn't help then it mostly is either power supply or motherboard's problem.

ack aopen - check for blown caps first

using a paint brust to paint the ram slots and ram contact fingers with RP7 or WD40 works a treat - try it

Any luck? I have a similar problem. I was setting up a new HTPC and after getting everything up and running I was adding software. The computer did an auto reboot and then upon trying to restart I am getting continuous long beeps.

I'm thinking the RAM had an internal error but don't have any compatible RAM to try and swap.
