Hey, im going to (attempt to)build my first comp (ever), and im getting Athlon XP 1800+, an Nforce (undecided what brand), an Antec sx840 case with 2 fans and a 400watt power supply, a creative modem blaster v92, and im using my older 40gb 7200RPM harddrive (not sure what brand it is, because i got this current comp from gateway), a cd-rom,cd-rw, floppy drive, and geforce 2 ultra, from the same comp. I'm going to install Windows XP Home on the comp im building, and i need to know how to erase EVERYTHING on my harddrive, and i need to know whether to use NTFS or FAT32 file system, and if i (really) need a DOS partition...You can tell im new at this eh? heh thanks ahead of time..
