I have an emachines 420 tower system which i am in the process of repairing. It has allready been taken to PCworld who said it was a blown PSU. I have tested the PSU (which was blown) and replaced it with a new 350w PSU. Now the machine does power on but i am greeted by the following beep code
beep           beep x 3          beep x 3              beep


there are no markings on the motherboard as to what make or model it is and i cannot find this machine on emachines website???

Can someone help as to the meaning of theese beep codes?

    Phoenix BIOS beep codes are usually 4 grouped beeps.  1-3-3-1  is 28 Autosize DRAM:  A power supply failure can damage anything it is connected to when it goes, because of the possibility of sending a surge through the wires.  This sounds like the motherboard has been damaged.

    During the POST, beeps are related to memory, so only the memories could be damaged.
    Try replace them.

    Not true - there are many POST codes in my link that refer to motherboard components.

    Didn't I say "This sounds like the motherboard has been damaged." in my first post, and therefore it would be the same answer as "Turned out to be motherboard that was faulty"?  If this is so, why the C grade?
