Defrag doesn't run

I tried to run defrag tonight, but it doesn't run. Any suggestions about what the problem is? Thanks!

You can open the Action Center (click the white flag) and go to Maintenance. Select Troubleshooting, and it will scan for issues. Did you analyse before attempting to defrag? It might not make a difference, but sometimes Windows 7 is a little picky about tasks. So far, it has been the easiest Windows for me to maintain. You can download a third party defragmenting tool, such as Defraggler, and see if that works. Hope this helps, and Welcome to the fourms, tubbfan! Post back if you have problems.

It says I have no issues.

Try some third party defragmentation programs:
http://www.diskeeper.com ( you have to sign up and its only trialware )
http://download.cnet.com/Smart-Defra...-10759533.html ( free and defrags files you use most automatically )
http://www.auslogics.com/en/software/disk-defrag ( Disk Defrag has a home use version and a trial version you can download )

try some of the third party defrag programs and see if they work.
I have a few more questions for you though:
1) what do you mean it "doesn't run" do you get an error message? Does the program not even appear to have executed?
2) what version of windows 7 do you have 64 bit or 32? it will help me refer you to more applications.
3) has the defrag program ever worked before? Have you successfully ran the program in the past?
4) have you tried to defrag in safe mode?

Does using a third party program really solve my problem?

All right, lets go to the defragmenter program. You will see a list of discs, the first will be your main (C), if your computer is fairly new with a recovery partition, there will be another drive (D), then there's another partition listed as System. Click the first disc listed (C), it will highlight in blue, select Analyse, it will take a couple of minutes, then report to you the percentage of fragmentation. Then click it again and select Defragment Disc. If this doesn't work, you have a problem with your software. Either it is corrupt or needs reinstalling (the OS itself). Are there any more problems that you are having? The reason I ask is, this is a software and not a mechanical problem. It should at the very least analyse it. No, a third party program will be a temporary solution. It will defrag your system, but the default one in Windows 7 is supposed to work. I've never had one that didn't work.

I go to START, and try to open disk defragmenter, but nothing opens. That's my problem.

If you can successfully defragment your hard drive with third party application then yes... Because you have accomplished the task of defragmenting your hard drive.

You can reboot your computer, hit F8, and restart in debug mode and see if it helps. Did the program ever work?

after you try to open the defrag program hit Ctrl + Shift + Esc to open the task man then goto the processes tab and see if you can see the process dfrgui.exe is it there?
