hey guys this is my first post so if im in the wrong forum area just let me know... but the problem i have is that i currently have 2 hard drives and a dvd drive. they equal 100 gig of space. I am trying to add a third hard drive so i can have 180 gig. the problem is my computer wont seem to boot up when all 4 ide slots are taken. ive tried to mix and match all kinds of ways and all the devices seem to work when theres only 3 hooked up (3 regardless of wich ones they all work) but once i try to add the 4th wether it be the dvd drive or the extra hdd it starts giving me problems and wont boot. ive tried all the devices by themselves with the 3 setup and they all work its just when i try to add the fourth i have problems. can I only have 3 ide slots taken up???
