I had a simmilar problem with the same motherboard. Changing the bios setting usb keyboard support from OS to BIOS fixed it.(might have got the name wrong, but if you go into the bios itd be obvious) The power supply is failry low for the setup you have, Id recomend getting a good 300 watt.

You have a relativley similar setup to what i had when i used that motherboard, the only extra things i could really suggest trying would be the earlier bios version 1.3 and trying a diffrent graphics card ideally a PCI one or AGP with no more than 8mb. That motherboard does seem to have problems with not being able to supply enough power to AGP.

Have you tried pressing F5 during install at the point where it says press F6 to specify additional drivers? In windows 2000 it then gives you a menu to select the type of computer you should try picking Standard PC instead of ACPI PC. A friend of mine has whistler and the installer seemed very simmilar so i suspect it should have that option still. I had a Gigabyte GA-5AA (got an Abit KT7-Raid and a Duron 600), I Wasnt too impressed with the Gigabyte BIOS`s myself, I thought 5AA.F3 was the latest Bios version. From my use of the GA-5AA Bios version 1.3 seems to be the best id recomend you try that. you do not get ACPI mode using that either.

GetRight can have a similar effect, locking the save to directory in use.
