I just tried to format my computer and then reinstall windows, but when i booted with the windows CD in it didn't find any harddisks. My computer (and harddisks) work fine in windows. I have formatted my computer a couple of times before but not since I bought a new mothercard, processor, graphics card and memory.
My computer:
Intel Pentium 4 3,2 GHz
Asus P5GD1 mothercard
Sapphire X600 XT 256Mb PCI-E Vivo
Twimos 512Mb DDR400
Hitachi Deskstar 7K250 80GB
Samsung SP1604N 160GB
