Hi Dale, The error message at shutdown you refer to could be caused by numerous things. One is the presence of the W32/Kriz virus. Another is having multiple versions of AOL installed on the machine. Since you are an AOL user, that might be an issue for you. The error message has also been associated with McAfee's firewall. The problems described with the hard drive may be related, or may be coincidental. I would suspect things like the BIOS is too old to handle a drive as large as 120 gig, the BIOS is not properly set for the drive, not recognizing the drive, or not correctly detecting the drive. Here's a good site on troubleshooting hard drive problems: http://www.zdnet.com.au/insight/0,39023731,20267667,00.htm The W32/Kriz virus is a pretty nasty one. It can affect the BIOS of the computer by attempting to flash it. Here's a page on that: http://securityresponse.symantec.com/avcenter/venc/data/w32.kriz.html and it could explain the hard drive problems. I wouldn't jump to the conclusion that the motherboard is shot. Maybe it is, but the probability is rather low; that's a relatively rare thing to happen. The fact that you're getting the same or similar problems on the original drive makes it sound like a BIOS issue to me. It could be as simple as replacing the battery on the motherboard so the BIOS settings are correctly retained between shut downs. Do you get any error messages during the POST (the black screen at boot where the memory is checked before Windows starts to load? Does the BIOS correctly identify the drive then? That's where I would start. Hope this helps. Ron Mac> Addendum: Now (about 5 days later) I'm getting the same problems on the Mac> 40 gig that were on the 120 gig. As far as I'm concerned it's just GOT to be Mac> the mother board!!
