Re: GeForce 8600GT & 4GB Ram Is this a BIOS error? If so, then don't worry about Windows patches for now. Either your motherboard doesn't support ACPI, you don't have the latest BIOS, or you don't have it turned on. I had a similar problem with my motherboard (which is well over a year old now) but a BIOS update solved everything. What motherboard do you have? |
