My Aurora R2 has a problem.  On power on, it reaches posts and then starts beeping continually, it sounds like two beeps repeated every second. After leaving it a week it will turn back on again usually to work for a day after which it returns to this state. I am wondering if these two beeps are mean't to be indicating Ram problems, I have opened it up and checked the seating of the ram. I have also used the diagnostic program to check if their is any ram problem and has not shown any. I have also updated to the latest bios and ran a huge array of virus malware checks. Any advice on the next stage please.

Thanks
