Allright very good. The beeps that you're hearing are POST beep codes which only beeps when there's a HARDWARE problem to warn the user from future conflict.
Possible reasons:
1. Processor/Ram heating up
2. Cards are not seated properly
3. I'm 80% sure that your card is drawing more juice than what your PSU can deliver, thus making it warn the processor/motherboard which causes the Beeping sound.
Are there any other symptoms?
P.S. I'd love to fix this for you via teamviewer, but it's a hardware issue not a software issue therefore it cannot be fixed via teamviewer.
