Cannot read disks using lite on LH-18A1P

I just installed the lite on LH-18A1P combo drive. I run Vista Ultimate.

My problem is that if I load a disc into the drive - either dvd or cd nothing seems to happen.

If I go to my computer and click the drive it starts to load but stops at about 95%. Then my computer locks up.

I have to eject the disc and reboot to get the computer working again.

I had an LG before this and could not burn anything so tried the lite on.

I am new here and hope this is where I post my question.

I hope someone can help me with this problem. I’ve had it for a week now and cannot work out what to do.

Thanks

Fixed.

It was the IDE cable!
