Personally I use Chrome, for me it is the fastest of all the browsers, but click here for some suggestions from Microsoft. It sounds though as if you have some add-ons running on one machine that you don't have on the Vista laptop. Have you checked that?
If you're still on the old installation, and nothing to lose run these programs, Adwcleaner, TDSSKiller and Junkware Removal Tool. Reboot needed after Adwcleaner. Run all the others, reboot and run Ccleaner as well as its reg cleaner.
rdave13 I never thought of that and would have gone down that street.
Jock1e tried CHKDSK but no go still slow.
Yes to your last question just found how to do it.
Re-set Dell Inspiron one PC all in one.
Switch off PC
Switch on computer and tap f8 untill you get an option screen from safe mode, go-back, repairs, backups, and a factory reset with or without back up.
I did make three disks when I first bought it, I think it popped up when I first switched it on.
I also have just found the Diagnostics, utilities, and Drivers disk.
That would have been handy.
Ok its finished the new install, would you allow the (auto updates and alerts), plus (system and usage data.) I have an option to tick the boxes as its just finished its install.
