Windows 7: New dvd drive causes pc not to power on

New dvd drive causes pc not to power on

Bit of an odd one, i have just purchased a LG Gh22ns50 Dvd-RW Sata drive, and once i connect the sata power cable to it my pc will not power on, clicking the external or internal power buttons does nothing, i have tried all the usual fixes, changed cables checked connections, updated the bios i eventually completely rebuilt the pc however if i connect the dvd drive the pc shuts down instantly and will not power back on till i disconnect the drive and than turn the power supply on and off.

However i can actually get the drive to work i have one of those internal hard drive readers that allows you to read hard drives via a multi adapter and then into usb, it has its own power and connects to my pc via a usb cable, if i plug the drive into this than not only does it power on but windows can read it fine. my other dvd drives are ide so i thought it might be something to do with the motherboard (Asus p6t) drivers but they seem up to date

anyone have any ideas why this is happening and a possible fix?

(my power supply is 1200w and is nowhere near capacity)

Do you have another power cable inside the pc to try? What if the SATA cable is not connected, will it power up?

Replaced the drive with a new one from the store, same problem, however once i plugged it into a different line of sata power connectors from the power supply (the same one as the hard drives) everything works fine, it operates fine and the computer works perfectly, so i take it something is wrong with one of the power supply's sata power lead things (power supply has two long cables each with 4 sata power leads on it). I did try using various leads out of it both the end and a middle one both cause the pc to power off,

so anyone know what would cause a power supply to do this?

If available, you may want to use the PSU manufacturer's forum. You might not be the first to experience that problem with that unit.

USB External Drive doesn't power off when safely ejecting
Hi all, I was wondering if I would be doing harm to my drive by ejecting and unplugging while there is still power to the drive. Is it basically the same as not ejecting? In XP my drive would power off in Windows 7 it does not.

BSOD for power drive state failure
My laptop is fairly new and should not be giving me the issues that it does. It suddenly started blue screening for no reason. I don't have to be doing anything, it will just crash for no reason. I have done a full system wipe and it still crashes. I need help.

I forgot to copy the information i had in the window that pop'd up. I have a dell n5110 and am running windows 7 64bit with intel core i5. I believe that this has something to do with my wireless drivers(or is affecting it somehow.) Any help would be appreciated. Thanks.

Installed W7 & SSD Drive, PC will not power off
Hello - After installing W7 on my laptop with great success, I decided to go for it on my desktop. I bought an Intel 160Gb SSD drive (S2 so I could use TRIM) and W7 Pro.
