Strange MSI K8N NEO Problems

[The6thExtinction]

I am having problems getting my liteon 811s dvd drive to work on my MSI K8N neo. Im pretty sure the problem is the motherboard. I did have the drive working for a while but one day it stopped working. It will show a cd and you can get into the folders, but when it tried to copy data the program that is trying to acess the cd just freezes. Another weird thing is that i can burn dvds ok. I have tried installing windows (in dos) on to a dinfrent hard drive and the installation just froze. I poped the drive into my older computer and it worked with no probelms. Another thing i tried was clearing the CMOS. That improved things temporarly, it would copy a dvd and after 40% it would crap out. After a restart it would not work like normal. I have also tried switching IDE cables.
