Hi i have just finished building my pc and have posted a message b4 of it not being able to post, but for all you who want to know, it was a faulty gfx card and not to do with the ram. So i did all this and booted it up and the harddrive is connected to the primary ide and the dvdrw and dvd rom drives are connected to secondary ide, dvd rom as slave and dvd rw as master. i booted and first it doesnt recognise the dvd rom drive and recognises the dvd rw and hdd, but sometimes the dvd rw is scrambled letters for some reason. so i plugged the dvd rom into the primary ide as slave on same ribbon cable as hdd and then nothing on the primary ide was recognised. so i unplugged the dvd rom altogether and it worked and i installed windows. but what was causing this as i still want to install this drive? could it be that the jumpers were set incorrectly as i think this is the main problem. Sorry to all who cant read this because of my lack of paragraphs.
