Help Im slowing down

[talos]

When I first start up pages load quite quickly, but as I continue loading checking e-mail and various forums for new content the new pages seem to load slower and slower, in fact some fail to resolve altogether, Ive tried flushing the DNS but this seems to make no difference, in fact if I leave the comp alone for a while it works OK when I start back. This seems to indicate a problem with the server, I use Idnet DNS servers, would changing to Open DNS or Google make any difference in pages resolving quicker ? or is there perhaps another way?.  I use IE by the way,  and have tried others but the problem seems to persist.

What version of Windows and IE?

One or two thoughts here http://lifehacker.com/5833074/how-do-i-stop-my-browser-from-slowing-to-a-crawl & http://www.wondershare.com/disk-utility/internet-explorer-slow.html

Also try running CCleaner http://www.piriform.com/ccleaner

Malwarebytes https://www.malwarebytes.org/

Auslogics Disk Defrag http://www.auslogics.com/en/software/disk-defrag/

Take care when installing these, they may ask to install toolbars etc.

Thanks for the suggestions
                                          I have run Ccleaner, very good prog had it for years
                                                  "      Malwarebytes  nothing found
                                                  "      Defrag all drives, not the same one as you suggest, but a good one from Piriform.
          None seem to have effected a cure, I am running Win 7 with IE 10 as my browser, but I have tried Firefox and Google Chrome. As you may have gathered I have had this problem for some time, but it seems to come and go although my internet use has remained the same, its a kind or ritual every morning.
                   Thanks again for trying

AV program causing the problem?

Lots of tips here that may or may not help http://www.bleepingcomputer.com/forums/t/87058/slow-computerbrowser-check-here-first;-it-may-not-be-malware/

Not thought of it as an AV problem, Ill try with it switched off

Call up task manager to see what processes are hogging your system.  Betcha it's IE.
