Acer or M$?

I decided, oh I'll hook one of my IDE HDDS up today, because I dont have a massive PSU with a million P2 connectors on it I thought I'd unhook my CD-rom drive (Who needs one if you have a DVD/CD-RW burner combo?) So I unhooked it, cut my hands up hooking the HDD up and rewiring things..... Went to boot my computer, nothing.... I though hmmmm Ram? So I pop my added PC2700 out.... no boot.... ok what did I fry? I Yank the hard drive out..... still no boot..... ok what is wrong here? my parents will kill me if its fried.... so I plug the CD-rom back in just because.... what do you know, boots.... ok.. I Shut it off, unhook CD-Rom drive, it wont boot, but before it blue screens and restarts I quickly plug it in, and low and behold windows loads a second AFTER I plug it in..... can somebody explain to me what the heck this is? I mean..... a CD-rom NOT letting windows boot, does this mean it doesnt like hardware change, or its just a POS? I am really frustrated and irritated that I need to have a CD-Rom drive hooked up to run my OS when I could have another 160 gigs..... Bah!!!!!!! Any ideas?
