Adding 2 IDE drives to a new Mobo with a Serial ATA drive, XP reboots automatically

Hi everyone,

I just upgraded my motherboard to the DFI LanPartyUT NF3, and bought a Serial ATA drive to replace my old 120g IDE drive as my primary OS drive (Win XP SP2).  I first loaded it up with just the ATA and installed the OS.  Everything was fine.  Then I tried to put the 120g drive and another 80g IDE drive on IDE1 as Master/Slave.  When I boot up the computer the Windows XP black loading screen comes up, then it goes black and reboots.  I've tried just 1 drive at a time, and tried putting them on a SIIG PCI IDE Controller I have as well.  Same thing any way I do it.  I take them out of the loop, computer boots just fine.  Anyone know why it won't boot with the IDE's plugged in?  ALso, neither of the drives i'm trying to add have an OS on them.

   When you boot up in XP with single hard disk, did you install all the drivers come with motherboard CD?
If not, then please install them first. Because this is a Nvidia chipset motherboard and need to vendor's drivers to
be able to use them.

   After intalled all the drivers, then try to put one IDE drive and boot up again.


I suspect your power supply may be too weak, calculate your needs :


also check if it is delivering enough amps on the 12V rail

Wesley - Yes, I did install the Nvidia chipset drivers from the manufacturer of the board.  I have not downloaded the latest from Nvidia though.

Nobus - According to that chart, with just the ATA drive installed I need approximately 295 watts.  If I have all 4 hard drives plugged in (the ATA + the 3 IDE drives I would eventually like to connect) and the SIIG PCI controller card, I'd need 393 watts.  The new case I bought has a 380w PS.  If I remove 1 of the IDE drives from power, and take out the SIIG card, it says I'd need 343 watts, so I should be good with that config and the 380w PS correct?  I have a 450w PS that I could try I guess.  Where do I check on the amps to the 12V rail?

Also, the manufacturer wrote me back saying that sometimes they have seen situations arise with the Nvidia chipset where if the drives you are trying to add are not completely clean of all data (0-byte'd), this could happen.  One of the drives I'm trying to connect has about 60g's of data on it, but the other is completely cleaned by Partition magic.  Neither one plugged in by itself works.  I've already ordered another 160g ATA drive, I'm just gonna screw this idea and convert over to ATA completely I think, it's only $110.  Maybe i'll drop the 120g drive I have into a external USB case.
Hi Longshot9

>> Where do I check on the amps to the 12V rail?

sticker on psu

12 volt is used for CPU , GFX if molexpowered, fans & drives

Roughly estimate

CPU =6-8 amps(2500+-3800+), GFX 5-7(>9800/5900) amps, fan=0,5 amps, drive =0,75 amp

you do the calculation

Have you looked in bios to see if it sees the IDE drives?
For the 12V rail, on all the devices are the power consumption numbers printed, it is a simple sum to add them, and compare the result to the figure on the Power Supply.
The reason i talk about this, is tthat when adding devices to an existing system,  the 5V and the 12V amps needed will increase both, but in many cases, the 12 V needs rise over the max Amps delivered by the power supply. This applies to all sytems, but many "known brand" sytems are tailored to the needs of what is bought, and does not have much left for extra devices.
