I have major problems with my pc. Yesterday morning when I tryed to start up my computer I got the blue screen of death. I have Windows XP and here's exactly what it says when you try to start it up, STOP: c000021A (fatal system error) The windows logon process terminated unexpectedly with a status of 0x80000007 (0x00000000 0x00000000). The system has been shut down. I tryed to run it in last good configuration mode, safe mode and debug mode all to no avail, it still brings me to the blue screen of death. I am not very computer literate, so any help would be appreciated.
