Vista - That o'l disk thrashing again!

OK, I thought I had cured my disk thrashing by turning of things I don't need. Then it came back again, and it goes on for more than an hour. Auto defrag is off as well. I do a lot of video editing and today have not been able to get on at all due to this disk thrashing again. The hard disk access stops smooth playback of video files. I tried running disk defrag and then stopped it. I think it may have made things worse by stopping it!
I'm now running Disk Keeper 2008 disk defragmentor, to see if it helps. It stated the disk was moderatly fragmented.

Im running Vista Home premium 32 bit, with 3gb ram, q6600 nVidia graphics card.
My performance rating is averaged at 5.4.
The hard disk is SATA ll 700gb 564gb free space
Intel core 2 Quad processor.

I have tried turning off Superfetch, it seemed to cut the disk thrashing, but then I noticed files were slow opening or populating the explorer view. It generaly slowed things. So activated it again.

Any tips to help speed up my Vista appreciated.

> OK, I thought I had cured my disk thrashing by turning of things I don'tHave you tried running a disk cleanup app such as Ccleaner? Do you have
enough free space? Did you have Disk Keeper do a "boot time" defrag as well
as a defrag in the GUI?

Is search index running?

Speed Up the Performance of Vista

I hope this helps.

After installing a trial version of Diskkeeper 2008. I ran a defrag. Seems to have helped, as I create and delete a lot of video files. Seems to be running a bit faster now. Just that the original Vista defrag, is now missing from my tools menu.Disk keeper seems to have replaced it. Will the original Vista one return if I uninstall Diskeeper I wonder?
