IE8 stopped working after 1 hour

Hello,
I have installed IE8 to my windows xp.
It did work fine just for 1 hour after that it suddenly stopped working.
I tried to open it many times but still unable to open it.

Edit: I split your topic off from the thread by HarleyQuinn. Best to have your own thread.

The first thing to try is to reset IE8, see here: Reset IE8 settings

If no help then uninstall IE8 from Add/Remove Programs. Reboot and make sure IE7 is working okay. Then try installing IE8 again.

If the Reset doesn't work and you installed IE8 from Windows update. 1. Download IE8 to desktop, not via Windows Update. 2. Uninstall all third-party toolbars, add-ons or Windows themes. 3. Close all open applications 4. Create a Restore Point. 5. Uninstall IE8 (roll back to IE7) and re-boot. 6. If W7 is working OK, create another Restore Point 7. Temp. disable all security apps. and any third party firewall (leave XP firewall on only). 8. Install IE8 9. Re-boot Cheers, Lee
