GDay All,

Jamie, I had very similar issues with a Gigabyte GA-8I955X Royal motherboard
and WinXP Pro, including similar event log entries to 'The device,
\Device\Scsi\SI31121, did not respond within the timeout period'.

The problem turned out to be the South Bridge, an Intel ICH7 chip yours will
be an ICH4. It went bad possibly from overheating even though it was cooled
by a small fan.

All I can suggest is that you monitor the temperature of your south bridge
and if it seems excessive or, from cold, it heats up too quickly, then plan
to buy a new motherboard.
