Windows Explorer constant error

[Maniac618]

"Data Execution Prevention" came up to close Windows Explorer, here's the info on the problem...

EventType : BEX P1 : explorer.exe P2 : 6.0.2900.2180 P3 : 41107ece
P4 : unknown P5 : 0.0.0.0 P6 : 00000000 P7 : 0000dd4a
P8 : c0000005 P9 : 00000008

Anyone know what is going on?

Everytime I say close message the task bar disappears momentarily and then the icons in the tray reappear, then I get the "Data Execution Prevention" dialog box and close again.

It's continuous.

Is there anything I should do to act now before restarting the PC? I fear if I just restart I may not even get back into Windows XP?

Ok I restarted and all is fine, but what the hell could it have been?
