Good morning.
I have an acer aspire mc605.
suddenly turning it on starts from an electrical point of view but does not boot the bios.
I tried replacing the power supply, the battery, the RAM and disconnecting all the connected devices but nothing helped. removing the RAM at startup starts beeping continuously.
Can anyone help me?
thank you and happy Sunday.

    I'm sure that you have but if you haven't then REMOVE THE BATTERY AND UNPLUG for a few hours (over night) as capacitors on the main board may still be supplying voltage to the eprom ? Elsewise you'll probably have to take to a repair shop.

    Good Luck.

    $48 for a motherboard but BE SURE that it's the same part #.

    Your system is more than ten years old, so it would be expected to have the CMOS battery go out on it. The battery is up between the expansion slots:

    Try replacing that and then do a clear CMOS:

    Then reassemble and try booting again.
