Now I know this topic has already been covered a while ago on here and I read it from beginning to end and tried everything and it did not fix my issues. So my computer got hit by lighting through the phone line. I have replaced the power supply and the motherboard and cpu which came as a unit. And when I boot up it finds my HDD and both my Cd-Roms but then I get "reboot and select proper boot device or insert boot media in selected boot device." I ran Knoppix and looked at the hard drive and everything is still on there. So I am guessing the problem is in the Bios but I have no idea where to go from here. Here is what I have going: Elitegroup Goal3+ Motherboard AMD Athlon Sempron Master Drive - Hitachi 2500GB HDD CD Drive 1 - Pioneer DVD-R/RW CD Drive 2 - Samsung CD-R/RW SW Generic Floppy Drive 3.5" 1024MB Kingston DDR Ram Thanks in advance for any help!
