Autocheck runs everytime PC boots up

Hello,

There can be several reason the check is running.

First of all, check to make sure it is actually scheduled for every run. Type AT at the command prompt to see the scheduled commands.

Try booting the machine in VGA mode and then shutdown, does the check still run?

Try manually closing all applications, including from the System Tray. Then check in the Task Manager to see if there are any applications showing up in the "Processes". If yes, try closing/killing them. do you still get the auto check?

One last thing I can suggest you could try is reapply the latest service pack.

Assuming you have NT Serevr, Install Service Pack 6 or you could boot the system in VGA mode & then shutdown the system. Check if you have set "autocheck on boot" using any third party tools like "Page file Defragmenter" etc.

Stop CHKDSK from running at boot time.

1.Edit: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager
2.Change the BootExecute entry from:

autocheck autochk * /.........

To:

autocheck autochk *

If you have scheduled CHKDSK for multiple volumes, there will be an autocheck entry for each volume. Delete the string from the BootExecute registry value for each volume you do not want checked. If you have NT 4.0, SP2, a new command line utility, CHKNTFS, will assist in preventing repeated CHKDSKs during reboots if the "dirty" bit is set. Type CHKNTFS /? and see KB article Q160963.
