I built a system and then turned it on and it posts... but then i fdisk and then formated and then booted from a floppy and then went to the cdrom prompt e:\ and typed setup... it does scan disk and then says it's scanning the system and then says it's coping the files but then 2 secs later it goes back to the e:\ prompt and that's all I can do... It reads everything at start up... Please help

Are you trying to install windows ? May be your cd-rom media or drive could be faulty. Try reading a different cd, if you cant read that your cd-rom could be faulty.
