Inspiron 8600 Refusing to eject disks

Its me again...

My computer has been refusing to eject CD's and DVD's. My father rang Dell and told them about it. They emailed me a patch, and it's helped, but hasn't fixed the problem.

 

Before patch:

Ordinary CD's (that programs need in to run) 60% chance of them getting stuck

Audio CD's 50% chance of them getting stuck

DVD's 99% chance of them getting stuck

Any CD's after installing something: ABSOLUTELY ALWAYS got stuck. 101% chance...

 

After patch:

Ordinary CD's: None have refused since patch

Audio CD's: One has stuck, four others have ejected normally

DVD's: 60% chance that I can't get it out

CD's after installation: Every single one has stuck since the patch.

 

I have tried everything. I've pressed F10, AltF10, CtrlF10, everything because F10 has a picture of a disk coming out on it. I've pressed the little button on the disk drive, of course. I've held it in for a minute. I've gone into My Computer, checked the drive properties, told it to eject from there. I've gone into Media Player, and gone Menu-Play-Eject Disk, with every type of CD. No results. I've done everything short of prising the drive open with a chisel.

 

The only thing I've found to work is to restart the computer. They always eject after restart. I don't know what to do about this irritating problem.  Can anyone help me???!!!
