[cjsnyxz2008]

recently each time I restart windows,
I got a message before login :
The instruction at :0X0023fedc"
reference memory at "0Xffffffff", The memory could not be read

click on OK to terminate the program.
click on CANCEL to debug the program

No matter I click CANCEL or OK, the message window is gone and
the login window be activate window. No debug program show up after I login.

I run Check Disk for both
Automatically fix file system error
Scan for and attempt recovery of bad sectors
but not help

the system is win xp professional

Anyone know how to fix it

Thanks

Finding out which program is crashing would be the first step.
