Okay, I copied the newer ASACPI.sys over successfully in safe mode, and rebooted. So, exactly what do I click on on that nvidia page now? addendum: Okay, I see nForce in the first radio box... but have no idea what to set the rest of the radio boxes. And selecting Option 2 and clicking the Motherboard button tells me it can't identify what ones I need, and directs me to enter that stuff manually again.... but since I have no idea what chipset I'm supposed to be setting it for... oO addendum2: Just dug out the box my mobo came in to look at the mobo book and stuff... and there's an install DVD calling itself M2N68-AM PLUS, and it calls itself nVidea GeForce 7025/nForce 630a Chipset Support DVD Rev520.07. Duh! Install from that?
