ASUS A7N8X-E Deluxe MB Boot Failure

[Ajak]

I fitted a new ASUS A7N8X-E Deluxe Motherboard (Serial#: 3CMM7J5340), 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 Pro (it got as far as the Safe Mode option Screen, I tried them all), 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 & Case fans until the speeds registered in the BIOS (about 2600 rpm) 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.

System specs:
CPU: AMD Athlon XP 1.6
Ram: 256 Meg Crucial Memory
Primary HD: 40 GB Western Digital Caviar SE
Secondary HD: 120 GB Western Digital Caviar SE
CPU Fan: Thermaltake Volcano 9+
Case Fan: Thermaltake Smart Case Fan 2
PSU: Q -TEC 400W Dual Fan Gold Low Noise
OS: Windows XP Pro (Already installed on HD from previous ABIT KD7 Raid MB)

Try resetting the board.
You can do this disconnecting the battery and moving the jumper close the battery on the 2-3 position for some seconds, then put the jumper again in 1-2 position. You will find two jumper close the battery. The jumper for resetting should be indicated on the manual as well as on the board (even if without the battery you can do the operation on both the jumper).
This operation will reset the bios setting all parametrs on safe mode (100 MHz FSB etc..) then you can try to modify the bios with the correct values. But take care because all wrong setting will oblige you to repeat the resetting operation.

What do you mean you can't boot into windows? Does your XP boot screen start, and then reboot the system just before you'd see the login screen? If so, you've probably mounted a new board into an existing windows installation, try doing a repair install from the CD.

PROBLEM SOLVED!

To all who suggested a repair install, you were right, I booted from a Win98SE boot disk with CD support & from the A: prompt went to C: & viewed the RAM drive files, which made me realize the MB must be working. Remembering I had an old 800 Meg Conner HD with Win for Workgroups 3.11 on it, I put it into my HD Mobile Rack and booted, within a few seconds I was in Windows. I will now try the repair.

Thanks for the help.
