i'm running windows 2k and the machine will all of a sudden reboot. After it restarts I check the event viewer and this error is listed under savedump

The computer has rebooted from a bugcheck. The bugcheck was: 0x0000007f (0x0000000d, 0x00000000, 0x00000000, 0x00000000). Microsoft Windows 2000 [v15.2195]. A dump was saved in: C:\WINNT\Minidump\Mini111801-21.dmp.

I checked out the minidump folder and there is 139 different files with dates it "dump" what ever it is doing. If anyone could e-mail me a response back at cmd_spook@hotmail.com, it would greatly help.
