Hi ! I've got a Winfast 760M02-GX-6ls
First, ensure that the leads from the motherboard to the internal speaker are connected.
Second, try "flipping" the connector, at one end, to make sure that you got the "positive" and "negative" leads correctly connected.
Third, put a multimeter onto the leads on the motherboard, and then turn the computer on,
and watch to see if the multimeter records any voltage where the "beep" should be.
Fourth, try replacing the AMD CPU, if only temporarily.
