May sound strange but open up your computer lay it flat and check the psu connectors to the motherboard.
See if anything may have wiggled up abit or check for chipped wires.
Also read this before you comeback:
Power-on self-test - Wikipedia, the free encyclopedia
POST AMI BIOS beep codes
1 Memory refresh timer error
2 Parity error in base memory (first 64 KiB block)
3 Base memory read/write test error
4 Motherboard timer not operational (check all PSU to MB connectors seated)
5 Processor failure
6 8042 Gate A20 test error (cannot switch to protected mode)
7 General exception error (processor exception interrupt error)
8 Display memory error (system video adapter)
9 AMI BIOS ROM checksum fix
10 CMOS shutdown register read/write fix
11 Cache memory test failed
12 Motherboard does not detect a RAM module (continuous beeping)
If its not anything loose your last bet is to rma the board with acer.
Tell them you have verified it is a bios problem and they need to replace it or give you a replacement board if necessary.
