STOP: C000021A (Fatal System Error). The Windows Logo Process System process terminated unexpectedly with a status of 0xc0000005 (0x0000000 0x0000000). The system has been shut down.
Will not even let me do a CTRL/ALT/DEL to escape.
Here's what I did --
1) Been hit consistently with a VeryLince virus. Ran Virusscan in safemode and cleaned up. Don't know if that was the cause. Viruscan noted several files in system 32 infected. Total files affected with PUPs and VeryLince totalled 39.
2) I went into to Microsoft and downloaded any XP updates. Not sure if this will work as yet since I haven't logged on since then. Also, clicked on the box that appeared that said I should send a message to Microsoft. Message sent.
Thanks to everyone for any input.
