When you start your PC the motherboard does a self-check and a single beep is what we want to hear (this is referred to as the POST or Power On Self Test beep). If you hear more than that, then the POST check is saying it found a fault trying to boot. This can generally either be due to a faulty or a loose component.
One long and two short beeps indicate the memory RAM, so the easiest would be to open your system up (shut it down first and unplug the power cable) and remove all the RAM sticks and plug them back in. See if you still get beeps. If so, turn it off again and remove all but one RAM stick. See if you still get beeps. If so, take that single stick out and put it in the naughty corner and try the next stick. Go through all the sticks you have in there one by one. You might see the system booting up just to present you a Bluescreen of Death called “Memory Management”, which indicates the same as the two beeps. Just continue with the test.
Hopefully, the system acts normal at some point, so you can single out a RAM stick that is causing the beeps. Give us a ring to see if we can exchange that stick under warranty. In most cases, it’s fine to use the PC without the said stick, but it will most likely feel a bit sluggish if you do.
