PS/2 Keyboard not Working

I just had a 761GXK8MB (with Athlon 64-bit CPU and new power supply) installed into a Dell Dimension chassis. I tried using a PS/2 keyboard (two different ones) along with serial or USB mouse, and it would hang up (or delay a long time) in POST whenever I kept the PS/2 keyboard plugged in and pressed keys. Even if it booted I could not use the keyboard in Windows. I finally had to buy a USB keyboard as solution. I checked BIOS Setup and didn't see anything I thought would cause this behavior. Why would the PS/2 keyboard not work?

    I don't mean to be contrary, but doesn't the Super I/O contain the PS/2 controller and the "south bridge" contain the USB controller? I'm not sure how the north bridge would cause this, so please elaborate. I thought it might be more likely a problem with BIOS settings, or maybe a bad solder joint on the PS/2 connector.

Ps/2 means the north bridge chipset is going ( just not totaly dead though ) in time you may notice the usb may not work at 2.0 speeds

Sorry nobody on this planet can repair a ps/2 unless another motherboard is purchased .

Athlon processor upgrade assistance:


Go to this link:

http://us.msi.com/?func=searchresult&keywords=ms-7025

Select the model motherboard you have and click on the CPU support link, it will show you a list of CPU's that are supported. You have a socket 939 board and AMD CPU's are now AM2, AM2+ and AM3 socket, which are 940 pin. It may be difficult to find a new CPU for your motherboard that is new since they have not been made in awhile.

I can't seem to find any usefull information as to why there may be a LED flashing on the motherboard. Re-check the memory speed, and configuration, as well as the CPU that it is supported. This seems to be a fairly new motherboard, it may still be under warranty, contact MSI and request an RMA if you feel the motherboard is faulty.

Hi jdnimrod,
This is not you're first post about the Foxconn mother board.
You have an issue with the PS2 keyboard as well. This Foxconn model ( 761GXK8 you listed ), is not 100% correct.
Please check this link:
http://www.foxconnchannel.com/EN-US/searcher.aspx?key=761GXK8
Find which is you're board.
Than post back into this answer.
It is important you run the exact CPU that is compatible with the mother board.

Shutdown


Auto shutdowns can be any number of problems but since it seems to do it about the same time frame of turning it on then I would verify and make sure that the heatsink / cpu fan is installed correctly and thermal grease has been applied. Also run a memory check as failed memory could also result in a simillar problem. Another source of problems simillar to this would be the power supply.

Foxconn uses the Award bios. One beep repeating means, check for improperly seated or missing memory. You can find that here. http://bioscentral.com/beepcodes/awardbeep.htm
Remove your memory & re-seat.

Not posting


Maybe a silly question to ask; but did you connect the processor power lead, as unlike some processors this needs a seperate supply.
