I built my own computer (first time building one from scratch) a few weeks ago. I had my applied tech teacher watching over my shoulder the whole time.
I had XP on it running smooth for a week and a half. Everything was working fine, untill I tried to install Ubuntu and some other stuff. VERY long story short. I went through **** and back getting my system to work again. 90% of my problems were due to a faulty IDE cable going to my HDD.
Now I have a new IDE problem. After 3 days straight of work on this machine, I figured out the first IDE problem, everything booted up, the XP install disk loaded with no errors this time. Everything worked.
Ok... I turned off my box, and plugged the second IDE connector into my second 200gig hdd (so now I had both of my 200 gig hdds connected. When I started my computer, the CD rom drive didn't start up, as if it wasn't getting power at all. Then i checked my BIOS and NONE of my drives were showing up. Niether of the hard drives, or the CD rom drive.
I hadn't changed any of the setup at all, all I did was plug the other 200 gig hdd in (mind you, this is the HDD that I went through **** and back with, with the faulty IDE cable).
So next I tried messing around with some stuff, and quickly figured out that if I unplugged the CDrom IDE cable, and left the molex plug in the CD rom, that when i started the computer, the CD rom drive would start right up as if nothing had happend. But as soon as I but the IDE cable back into it and started up the computer again, the CD rom drive wouldn't turn on once again. I'm assuming its doing the same thing for my HDDs, which is why nothing is showing up in my BIOS.
I've tried 3 different CD rom drives, and they all do the same thing. IDE cable plugged in = no workey. IDE cable unplugged = start up perfectly normal.
I don't get how plugging my second HDD in:
1. even effects the CDrom drive on a completely sepereate ribon.
2. makes it so that none of my disk drives show up in my BIOS anymore.
before you say anything. I have tried going back to the setup that worked perfectly before I plugged the second HDD in. And now its still doing the same thing. In fact, even if I don't have ANY hdds plugged in (both the mobo end and the hdd end of the cable are completely unplugged), the stupid CD rom IDE cable still screws with the CD drive for some reason. I also have tried all of the different combinations of hdds being plugged in and CD rom drive plugged in.
I just want my computer back!!!
