When I start a bigger movie with BSplayer the computer restarts after making a minidump...

Event viewer tells me that there was a Save Dump:
The computer has rebooted from a bugcheck. The bugcheck was: 0x0000007f (0x00000000, 0x00000000, 0x00000000, 0x00000000). A dump was saved in: C:\WINDOWS\Minidump\Mini011404-01.dmp.

Any Clues??
