Lite-On Drive Does Not Spin Up, Except After Restarting

My LiteOn doesn’t spin up CDs anymore after reinstalling my windows. The CDs are not recognized. My Computer freezes when I open to look at the CD drive (explorer.exe freezes). The weird part is that when I restart my PC, the CD spins up as soon as windows XP (SP3, PRO) starts to load and I can read the CD fine. After I eject that CD and put it back in, the software again doesn’t load and explorer freezes. Is this a drive problem? Doesn’t seem so to me, but I don’t know what else it could be.

You think the problem is with unhealthy registry even tough this is a new installation? Anyway, I have jvPowerTools and can give it a shot. At this point I have taken apart the whole PC.
