When my physical memory reaches about 70% my motherboard starts to make a continuous beeping sound. This has never happened before, but after taking my PC to a fix-it place, it happened within the first 30 minutes of getting it home. After reading this http://www.computerhope.com/beep.htm it seems I may have a RAM problem, but how can I know for sure? The computer fit-it person said that the computer had a power surge, but I'm not sure if this is even possible since the computer being connected to a surge protector. Any help would be much appreciated, as always.
