FOXCONN K7S741GXMG-6L Hi, WONDER IF YOU COULD ADVISE ME ON A FAULT. PUT IN AMD 2800+ PROCESSOR IN ABOVE BOARD TO TEST ITS OPERATION, BOARD WORKED FINE. REFITTED THE ORIGINAL AMD DURON 1200Mhz PROCESSOR NOW THE BOARD WILL NOT BOOT AT ALL, TRIED NEW MEMORY STILL NO GO, CAN YOU SUGGEST ANYTHING PLEASE ?

Hmmm, one beep is good! lol!

Means P.O.S.T. is good.

I see we're working with an AMD processor, and a Socket 462 (Socket A), motherboard.

Let's look at some basic installation problems for that motherboard, and see if any fit;

1) Since it is an AMD processor motherboard, you have to be SURE that Thermal Paste has been applied PROPERLY, and applied.

http://www.hardwaresecrets.com/article/274

An AMD processor runs hot, for the models that fit that motherboard.
If no Thermal Paste has been applied, the AMD processor could have burned up.

2) Anti-Static Precautions:
I know, I know. But you would be surprised with those of us, who do not know what Anti-Static Precautions are; and work on computers.
(Hmmm, wonder why it doesn't work? Must be a bad motherboard)

3) Mounting to the Support Plate.

The Support Plate can be a separate metal plate; or is part of the computer case.
Mounting of the motherboard to Support Plate can be done with plastic Spacers; or metal Standoff's.

(Standoff. Shapes vary a little, but basically; 3/8ths to 1/2 inch long, hex shaped, threaded shaft on one end; and a threaded hole on the other end)

If a Standoff is NOT mounted to a motherboard mounting hole; and is just sitting out there on the Support Plate; it can touch exposed solder joints on the bottom of the motherboard, and cause a Short Circuit.

MOST of the time if the 'offending' Standoff is removed; or placed where it should be, (Motherboard mounting hole), then the motherboard, etc may be OK.

4) Power Supply:

If the Power Supply was on it's last leg, this may be the 'straw that broke the camel's back'. Power Supply went to the Power Supply graveyard in the sky.

If the Power Supply does not have enough power (Wattage, and Amp's), then you would also see the problem you stated.

New Power Supply, or old? What is the manufacturer, and model number?

What AMD Socket 462 (Socket A) processor did you install?
What Ram Memory?
How many optical drives? (CD/DVD drive)
How many fans?

Hi,


Sorry but that motherboard does not support dual core processors. The socket type is 478 which is Pentimum 4 and will support anything up to a 3.2 GHz processor.

i have same problem on my motherboard and it is due to damage, check and see if your RJ45 (lan) is disabled in the system bios.then see if you are not drawing more than 500ma on the usb. good luck!

Mike @ compurepair.

I can't get Foxconn's website to pull up ATM, but I had this sort of issue once before, and felt completely stupid once I figured it out, and this is going to sound strange, but, remove your CPU fan and try to power up. If it does power up, then your CPU Fan is shorting out the system. If that doesn't fix it, then it is possible that your processor is not supported by the motherboard.

Hope this helps!

Here's the manual
http://www.foxconnchannel.com/support/downloads_detail.aspx?ID=en-us0000187

The new RAM is faulty or incompatible.
Take out the old RAM and see if the error goes away. If it does the two sticks are incompatible. If not the new RAM is the wrong type or faulty.
Get a stick that matches what you have, and you should be OK.
try  www.crucial.com and use their memory finder.

maybe the problem isn't in the sound cards or buil-in sound cards, i'm sure it's the speaker your are using, it may have some power leakage or something of that sort... check your electric "ground" connection too.
