Would the motherboard be the problem, if the DVD will not open?

My question is this,

Would a DVD drive open normally by simply pressing the on button?
(All power cables, and sata cables are connected)

Also, wouldn't bios normally show up on screen connected to the motherboard?

It powers on fine, and all the lights are working.
The DVD, HDD and Ram are new, but the motherboard I bought was opened and through Ebay.

It is an A8XXM-E.

I do not think there are cmos pins ( if so, could you let me know where?)

I did take the battery out.

Are you able to see the dvd drive in the bios? if the pc recognizes it then it could just be stuck shut... i'd make sure it isn't in the drive bay crooked, it could have been a defective dvd drive you bought.... i'd go with that first...

yes pressing the button should open it. Clearing the cmos by removing the battery is just fine but that isn't going to do anything with your dvd drive...

The drive opening via the button is independent of whether or not it's connected to the motherboard or whether or not the BIOS sees it.

When you press the button do you hear it try to open the tray? Does it move slightly? I've seen this a few times. If the tray uses a rubber grommet and teflon drive pin, the rubber grommet can become smooth. This can cause it to slide on the grommet (rubber not sticky anymore) and if can't overcome the strength of the magnet {magnetic disk on the top of the spindle to firmly grasp the disk to the spindle) to open the drive. In these cases I've been able to disassemble the drive and clean the rubber grommet with alcohol. However eventually these drives will do this again.

If it uses a gear assembly to eject the tray, it could be the magnet (mentioned above) is so strong (especially when the drive is empty) that the motor stalls while trying to overcome the force needed to separate the spindle and magnet. Usually a paper clip can be used to open the drive via the manual eject hole on the face of the drive. In these cases sometimes the drive can eject the tray as long as the drive has a disk in it. This isn't always the case though. My son had a DVD drive that continually needed a paper clip to eject the tray. However the drive worked fine otherwise.

The Bios does not even show on the monitor, the case gets power, but that's it.

But a comment later suggested removing the battery should have sufficed, since an earlier thread had replied to reset cmos.

Just trying to find out for sure if I have a possible bad mobo.

Sorry I didn't realize that your issue was a non-POSTing system. I seen you asking about a DVD tray not opening and expounded on why that might happen.

If you are having issues with a system that doesn't POST. You have to eliminate all that you can. Use one stick of RAM, onboard graphics (ie no dedicated graphics card), you can leave all drives (HDD, SDD, ODD) disconnected. Make sure that you have your ATX power connector and CPU (EPS) power connectors plugged in, even disconnect and reconnect to be sure.

This will give you the bare minimum needed to POST. If it still doesn't POST, then you may need to go back further. Try removing and reseating the CPU in the socket. Verify the heatsink is firmly attached. Try the other stick of RAM and another DIMM socket.

If / once you have it POSTing, start adding stuff back one at a time until either it doesn't POST or everything is reconnected and working.
