Have you checked to see if it might be in your Scheduled Tasks? This could potentially be the source of your misery. In addition to daily, weekly, etc., the Wizard for schedulng a new task lists "When My Computer Starts" and "When I Log On" among the frequencies for running the task.
You can access Scheduled Tasks via Control Panel (by clicking Start Menu-->Settings-->Control Panel or by typing "control panel" in the Run command [Start Menu-->Run] ). The Scheduled Tasks icon will be listed under Performance and Maintenance if your Control Panel is set to Category Vew. If in Classic View, it will be one of the many icons listed in alphabetical order.
Once you find Scheduled Tasks icon, double-click to open. The tasks that have been scheduled to run will be listed alphabetically by name in the first column, so look for either "chkdsk" or "chkdsk.exe". It may be listed as "Check Disk" or "Check Disk Utility." You may also see some or all of the following column headings: Schedule; Next Run Time; Last Run Time; Status; Last Result; and Creator...providing more info for a particular task. You may want to check these out to see how or when chkdsk was scheduled to run as it currently does. If not all the column headings I listed appear, you can place your cursor on "Name" and right click, which will bring up these other headings; just place a check mark by all items if you want all to appear.
As for stopping the repetitively scheduled chkdsk function, if it does indeed appear here, just right click and hit delete.
If that does not work, right click on chkdsk again, this time selecting Properties. Remove the check in the box beside "Enabled (schedule task runs at specified time)." If the prior step (right click-->delete) did not work, it might not have have allowed you to change the settings if, for example, a password had been entered to prevent someone from stopping the task, or if administrator privileges are required. I would think that you would receive an error message telling you the reason, and prompting you on what course of action to take. Make sure you are logged on as an administator if your account is not desginated specifically as an administrator account.
If this fixes your problem, in order to make sure it is ENTIRELY fixed, I would re-boot and then attempt to manually run an "on-demand" Check Disk scan (which you should also do on a periodic basis after your problem is fixed). You can do this by double-clicking "the My Computer" icon on your desktop, then right clicking your hard drive [probably labelled Local Disk (C:)], then selecting Properties-->Tools tab-->Check Now (under Error-checking). In the new window that appears, check only the bottom box labelled "Scan for and attempt recovery of bad sectors" (this box automatically fixes file system errors so do not place a check beside the top box). AT THIS POINT, CLOSE ALL OF YOUR WINDOWS AND RUNNING APPLICATIONS PRIOR TO CLICKING ON "START." Although you will be prompted to do so if you forget, closing everything allows the scan to begin immediately, without having to wait for the next re-boot.
Due to the fact that I typed a lot of words, it probably will not work. But it woud be my best guess and something easy to check before the big-wigs have to put their thinking caps on.
Good luck, my friend.
