3 Long Beeps 4 Short (higher pitched) repeated 5 times; then PC starts

[huntsk]

I cannot find an answer to this particular sequence of beep codes. All in one is about five months old. After the series of 3 long 4 short beeps occurs five times, the PC boots to the desktop.

Any suggestions? The PC is under warranty, but it would be nice if there was a simple fix first.

The model is: M9Z62AA (all in one).

I have already tried to find these particular beep patterns from the links you indicated. Also, after the 3 long/ 4 short series repeated 5 times, the PC boots normally to the desktop.

Pulling out the wireless keyboard/mouse USB adapter and booting back up without it did the trick. When I plugged the adapter into a different USB port, and rebooted, no beeps. Suggested to client she replace both keyboard/mouse just to be sure.
