internet explorer has stopped working

i upgraded from windows 7 ultimate to windows 8 pro keeping my windows settings,personal files and apps as it is..the upgrading went smooth... but whenever i open IE10 it stops working and says "we're unable to return to..."
i even troubleshooted it's performance.... but no luck

EDIT: before upgrading i ran the upgrade assistant, and it said inte(r) network connections isn't compatible with the OS... so i completely removed it...then installed win8

Did you keep your antivirus or other security suite package from before the upgrade?

You might think about uninstalling it if you did, to see if it has a positive effect.

It's the most likely cause, assuming the machine connects to the net well otherwise, with other programs.

Other than that, make sure there is no proxy being set in I.E.'s properties.

If you have Java installed on the machine, update it to latest.
