Web page problems

Jeff121

I'm experiencing a problem when attempting to connect to some web links within some sites. For example tried to order a DVD from CD Wow and when I got to the "add to basket" link PC wouldn't connect so had to use laptop to make order. Also problems with onestopphoneshop when using PC but no problem when using laptop, can get onto OSPS website bring up an offer but when attempting to find out more details nothing happens, ie can bring up main page with offers but when I click on phone to link to offer the page goes blanc, but nothing wrong with website as I have tried same on laptop and website and links work fine. A few other sites getting a red x at top of left window where there should be an add or some graphics. Have uninstalled Internet Explorer 7 then reinstalled it thinking that it might be that but this makes no difference. Have run virus scan but nothing found am at a loss as to what to try next.
Any help would be much appreciated.
