I have an ASUS M3N78-VM mobo with WD 350g SATA drive running Win XP. Everything has been good for about 7 months but I now have intermittent problems when powering up the machine. From a cold start the SATA drive is not recognized in the bios and I get a BIOS message to put in a bootable media. If I leave the power on for 5-10 minutes and then hit reset or CTRL-ALT_DEL the machine reboots and the drive is recognized by the BIOS. Its intermittent in that sometimes I need to reset several times. Sometimes as soon as I enter BIOS setup the drive is recognized. I've tried the following:
- flashed the mobo BIOS
- plugged drive into different SATA port and power connector
with no success.
I also ran WD Data Lifequard which shows no errors
Incidentally the SATA DVD drive is always successfully recognized.
Can anyone point me in the right direction to diagnose further.
Thanks in advance
All with no success.
