Sounds like the CMOS is trying to tell you you either have a dead or all but dead drive, or the controller on the motherboard is going bad.
So, now you get the pleasure of figuring out if it's the hard drive that's the problem, or the motherboard controller. Replacing a hard drive is many times easier than replacing a motherboard, especially if you have a brand name system. If that's the case, and it's not under warranty, time to sell it on eBay if you ask me. Replacing a motherboard in those systems just isn't worth it.
My daughter is running Windows XP Home. About a week ago during boot up, her computer stalls and won't go no further with the display saying:
PRIMARY MASTER - FUJITSU XXXXXXX
PRIMARY SLAVE - NONE
SECONDARY MASTER - CD-R/RW
SECONDARY SLAVE - DVD/ROM GD800
PRIMARY MASTER DRIVE - FAILS
We have tried everything including safe mode but with no luck. Any ideas on how to fix this and the cause of the hang up?????
