Hi every one since yesterday afternoon since I first turned my pc on I've been having a strange problem were all four of my sata hdd's and dvd drive's keep disappearing in the bios. Every time I switch my pc on and off sometimes just my dvd will be there and not my hdd's or some of my hdd will be there and not my dvd drive. I have managed to boot in to the windows 7 disk a few times but it comes up with an i/o error saying to remove the problem drive which I have removed each drive one by one but still the same problem each time I turn the pc on sometimes the hdd's/ dvd will be there sometimes not. I have just replaced the bios battery but it's still the same. I am about to update the bios but I cannot see this fixing it as it has been fine for the last 6 months
Many thanks
