I have an ASUS P4S800D-E mobo that I'm trying to revive. However, the HD won't spin up unless I unplug the IDE cable. I have everything pulled off except power to the CPU and board. If I plug in power only, the hard drive spins up. If I plug in the IDE cable, no spin up, no post, no beep...just the fans start. I thought maybe the board was shorting against the case somewhere, so I pulled it out and remounted on plastic standoffs. I managed to get the drive to spin up once or twice, but most of the time it is not working. Is there some sort of internal short in the motherboard?
Which jumper? This system has been running fine for over 4 years. Just suddenly stopped spinning up the drive. It "fixed itself" intermittently, but finally just stopped. That's when I tore everything apart and isolated the behavior.
sorry, didn't get that from the first post.
I was referring the the cable select jumper on the hard drive. all (i think) IDE devices have a jumper where your options are master, slave, and cable select. I was thinking maybe if you were putting together a pc using many old parts, the hard drive may have the jumper set to slave instead of master.
"intermittently" ---- I would guess a bad cable. Its happened to me and believe me it was the last place I looked.
I couldn't tell from the pic's I found online, does your mobo have 2 ide channels or just one? Never mind, it does have 2, try the other IDE plugin on the mobo.
can you get into the bios if you leave your IDE cable unplugged? Maybe there's some weird setting where the board is trying to boot using SATA, but that really wouldn't explain the intermittent happening of this problem. Maybe it is a bad mobo
that's the way it's starting to look...I can get a cheap replacement for less than it's costing me in time and stress trying to get it to work. I was just wondering if anyone had seen this behavior before.
