Storage device error in wmp

When i'm watching a movie in windows media player, not sure if in other players aswell, i get storage device errors such as:
Cannot read data from disk, and stuff like that.
Could this be because i'm using a sata drive while i'm running a decent overclock?

possibly. did you lock the PCI bus?

have you run any tests on that hard disk?

PCI bus is locked. I haven't run any tests just yet. I'm trying other movie files to see if they get the same problem. No problems so far. I'll keep you updated.
