DVD - Drive ejects automatically

[The Incredible]

I'm having a Samsung DVD - Drive which nowadays ejects automatically. Sometimes just after i switch the pc on ,ie, boot it.

I'm using Windows XP sp2.

What could be the problem ? How to tackle it ?

If it's under warranty get the drive replaced. Samsung is known to have tray problems

its a well known problem with samsung.... even i am an unfortunate customer with one ROM drive and one writer and both have the same problem. No solution except as suggested by NucleusKore.
