What's your hardware? Please make sure you're using the latest BIOS and chipset drivers.

Hi! Sorry for the slow response, been away.

I've got the latest chipset drivers but I'm very unsure about the BIOS.

I'm running: Gigabyte p35c-ds3r rev 2.1

so i've been checking around on gigabytes site but the only BIOS related things are helping programs.

No direct updates / new versions...

please help :=)
