Msi 6390 motherboard problem ?

[ianr]

Right this is a friends computer im trying to fix.

hes got a msi 6390 board ver 2
2200 Athlon XP
256 ddr 2100 generic
Onboard Graphics, Nic & Sound
350watt Power
Latest BIOS and drivers
Windows XP home ed.

Right the problem is when you plug either a usb, rj45 or jack in the computer hangs. (all above are onboard)

I have tryed different PSU, graphics card & Ram and it still happens.

The only thing i can think it is now is either the CPU or Mobo.

He said the problems started just after he went on ADSL (British Telecom).
Is it possible that a electrical surge down the telephone line has caused this?

I havent got an AMD spare board to test the cpu tho.

Any ideas please...

BTW when the computer hangs i have to unplug the psu from the board.

Check the solder points around the I/O ports and make sure the I/O shield isnt touching anything.

I think vegasmc is on to something. it sounds like some sort of grounding or voltage problem, and by connecting an external cable you're affecting that. Check that their cable/cable box doesn't have voltage on the shielding, and check it's resistance to ground. it should be relatively low, maybe 100 ohms at most. Just a guess.

Anyone found a solution to the MSI 6390 USB/BT broadband modem problem?
I have the same.
I think it may be related to powesaving but I have now lost display functions after I messed with the power saving in the BIOS

Look forward to any replies

moral of story: dont buy msi and expect it to work! i have had the displesure of working on an msi mobo and let's just say it was, in a word, craptacular.
