<hr>What processes would be running that could prevent CHKDSK from running? Do i have to shut down literally every startup program? Even so, it doesn't work in safe mode either, i get the same message.<hr>Hi,
To run "chkdsk Volume: /f" the disk must be locked. In the case of the systemvolume (C: ), it cannot lock the drive, it offer to check C: at next reboot. Other volumes may or may not be locked.
An alternative when chkdsk cannot lock a drive; it may offer to dismount the volume. That is nothing I would try, risk for loss of data, and not for normal use. So just accept the offer to run at next start.

Also, when you say "it diseapeares after a second", have you tried to run them at the command prompt (cmd.exe) instead of Start > Run... ?
Have you looked at the System/Program log in Event viewer for odd error reports etc? Run "eventvwr.msc"
