I would wipe the computer and install Windows 7 from scratch, I have had endless problems from performing an upgrade from Vista. For one, Adobe flash, it screwed something up during the upgrade and I can never load sites that need flash, it has the bar up the top to install flash even though I have the latest, I choose to go ahead anyway to install it so the site loads, but no luck, I have even tried to uninstall it completely, then reinstall, still no good. Then again, it loads pages sometimes with no issue. I am going to install it from scratch again, just need to find the time, I have so much stuff installed like my media centre streaming software for one, which has halted the scheduled maintenance as I couldnt be stuffed setting everything up again....
