installed new motherboard, now can't see external USB drive

hi all

just installed a new MSI motherboard on my PC as the old Intel one fried. I
followed the instructions on their site and flashed the BIOS and downloaded
all the latest drivers. The PC now seems to be working ok and all the USB
ports are working when things are plugged into them, EXCEPT for my external
250gb hard drive which it just won't "see" at all. I've tried all the USB
ports but no joy. I tried it on another PC and it works fine on there so
I'm stumped as to why it won't work on here anymore.

Does anyone have any ideas?

cheers

See if the USB drive has a letter assigned in Disk Management.

nope, no sign of it. whether plugged in or not... I've also found that
when it IS plugged in, my internet connection dies (via USB too) and I can't
get any net access until the external drive is removed again...

Check Device manager for USB devices to see if you
have USB1, and USB2 (one should start with E (nhanced)).

sorry to be thick but, which section under Device Manager?

I'm not that thick, I was asking what section under Device Manager, NOT
what section is Device Manager itself under?...

Is this a 2.5" USB drive ?

2.5" USB drives that are bus powered, draw a lot of
current from the USB port. 3.5" drives usually have
their own power source (a wall wart), and don't draw
current from the USB port.

It could be, that if your internet connection comes from
an ADSL USB modem, those happen to draw a lot of current
too. You could be causing the overload protection to
operate, on your USB port.

USB connectors tend to come in "stacks" of two on the
back of the computer. Use a different "stack" for each
heavy loading device. If the ADSL USB is on one stack,
try the hard drive on a different stack.

Hi Paul, it's a 2.0 USB drive that has it's own external mains power supply.

I've tried disconnecting the internet/modem and trying the PC with only the
external hard drive plugged in via USB yet, it still fails to show up...

Um ... Universal Serial Bus controllers?
"USB" for short?

Generally the last thing on the list.
