I fitted a new ASUS A7N8X-E Deluxe Motherboard, when I booted up I got an audible BIOS message which sounded like "CPU fan fail", the machine then refused to boot into Windows XP, even though the CPU, Case & PSU fans were all spinning. I checked the hardware monitoring section of the BIOS and the readouts for all 3 fans was 0 RPM. Both my CPU & Case fan are Thermaltake with manual speed control, so I turned up the CPU fan until the speed registered in the BIOS but although the error message ceased I still could not boot into Windows. I searched the BIOS & can find no way of disabling the fan speed detection. Is this what is preventing the PC from booting? & if so what is the solution?.
This board was reviewed in Toms Hardware Guide but no such problem was mentioned, ASUS technical phone support for the UK is non-existent.
