When I try to defrag my pc I get a message that says "Disk Defragmenter has detected that Chkdsk is scheduled to run on the volume (C:). Please run CHKDSK/f. Don't know how to do this

if it is a windows computer, try running defragmenter and disk cleanup.
to run defragmenter, in the search box in the start menu (in vista and windows 7) and search "defragmenter" select the c drive, and defragment it.. while you're at it, set up a weekly defragment with the defragmenter schedule.
To run disk cleanup, search for "disk cleanup" in the same search box. select the c drive, and check all the things you want to clean up.
you can always just do a scan with your antivirus to check if theres a virus slowing your system down.

You may run or perform Disk Error Checking(This is for Windows XP SP3):
* Chkdsk (Chkdsk.exe) is a command-line tool that checks volumes for problems. The tool then tries to repair any that it finds. For example, Chkdsk can repair problems related to bad sectors, lost clusters, cross-linked files, and directory errors.

** How to run CHKDSK at the command prompt:

1. Click Start, and then click Run.
2. In Open, type cmd, and then press ENTER.
3. Use one of the following procedures:

To run Chkdsk in read-only mode, at the command prompt, type chkdsk, and then press ENTER.

To repair errors without scanning the volume for bad sectors, at the command prompt, type chkdsk volume:/f, and then press ENTER.

Note If one or more of the files on the hard disk are open, you will receive the following message: Chkdsk cannot run because the volume is in use by another process. Would you like to schedule this volume to be checked the next time the system restarts? (Y/N)

Type Y, and then press ENTER to schedule the disk check, and then restart your computer to start the disk check.

To repair errors, locate bad sectors, and recover readable information, at the command prompt, type chkdsk volume:/r, and then press ENTER.

Once done with chkdsk r, run FIXBOOT and press ENTER.

Note If one or more of the files on the hard disk are open, you will receive the following message: Chkdsk cannot run because the volume is in use by another process. Would you like to schedule this volume to be checked the next time the system restarts? (Y/N)Type Y, and then press ENTER to schedule the disk check, and then restart your computer to start the disk check.

Restart Windows by removing extra's hardware devices connected then you will find the option with start wilth last known good configuration. If not working then use windows cd to restore windows priviously.

Possible Solutions:
1. Turn page file on.

Turning the page file on is a relatively simple process. Begin by selecting Start and right-clicking My Computer. Choose Properties and then press the Advanced tab. Next, choose the Settings button that is located in the Performance area; choose the Advanced tab in this area, and then press the Change button that is found in the Virtual Memory area. There will be a choice called System Managed Size in the Virtual Memory area, select it, press Set (this one is important), and then choose OK. The final move is the most important one; at this point you need to restart the PC. After you finish following these directions Disk Defragmenter should be available to do its magic.

2. Re-register the defragmenters snap-in files

It is possible that you install a third-party defragmenter like Diskeeper, then on uninstalling, it does not restore the built-in one correctly. Open Command Prompt (good ol' DOS) by clicking Start -> All Programs -> Accessories -> Command Prompt. At the command prompt type,
cd \windows\system32And then register the defrag components, by typing:
regsvr32 dfrgsnap.dll
regsvr32 dfrgui.dll
At this stage, you may find the disc defragmenter works. If not, there is one more step you can do.

Using Windows Explorer browse to your windows\inf folder.
In there you will find a file called dfrg.inf right click this file, and select Install.

3. Check if you have enough free space on the drive you want to defrag. It should have at least 15% free space. A volume must have at least 15% free space for defrag to completely and adequately defragment it. Defrag uses this space as a sorting area for file fragments. If a volume has less than 15% free space, defrag will only partially defragment it. To increase the free space on a volume, delete unneeded files or move them to another disk.

4. Run CHKDSK on the volume first before defragmenting. To run chkdsk on a volume (partition, disk), go to Windows Explorer (not to be confused with Internet Explorer) -> right click the partition -> Properties -> Tools tab -> Check now -> place check marks as required -> Start

5. Check if you have the appropriate services running.

Start > run > services.msc [enter]

Browse down to these services and see if appropriate settings was set.
Logical disk manager - automatic
Logical disk manager administrative service - manual or automatic
Defrag with XP also needs the DCOM Server Process Launcher service running.

6. Your computer might have spyware or malware. Some viruses/malware are known to interrupt/disable system tools such as disc defragmenter. Try to download and run No Adware (download here), an anti-spyware and adware tool. You can also use Malwarebytes Anti-Malware tool or Smitfraudfix (how to use smitfraudfix?) to remove spywares or malwares that are running on your system.

7. Install and run third-party disk defragmenting software.

8. If all of the above possible solutions fail. I'm afraid you need to repair install your OS or as a last resort, reformat your computer (but yeah, I know, nobody want to do that just because of disk defragmenter).

if your having a blue screen error. Try to load your operating system CD and perform a CHK DSK by repeatedly press F8 on the pc, then boot to safe mode with command prompt..

Then perform this steps manually:

1. Click Start, and then Run.
2. In Open, type cmd, and then press ENTER.
3. Use one of the following procedures:

   • To repair errors without scanning the volume for bad sectors, at the command prompt, type chkdsk volume:/f, and then press ENTER.
     
     Note If one or more of the files on the hard disk are open, you will receive the following message: Chkdsk cannot run because the volume is in use by another process. Would you like to schedule this volume to be checked the next time the system restarts?
