when I try to open internet browser...it says 'a problem caused the PROGRAM to stop working correctly'.

is there a way to fix this?What kind of internet browser ?I know this might seem obious, but try reinstalling the browser. If it's firefox, it should ASK if you want to DELETE the settings first.internet explorerhow do you reinstall the browser?Run the System FILE Checker
Click Start/ All Programs/ Accessories
Right click on the Command Prompt option, on the drop down menu which appears, click on the Run as Administrator option

Start the System File Checker

In the Command Prompt window, type: sfc /scannow, press Enter
You’ll see “the system scan will begin”.if this doesn't work download latest version of internet explorer and install.
alternatively you should try firefox For now, ignore the posts by moro.

What is new or different since the last time everything worked properly (ie, new hw, new sw, virus, error, etc)? And what is the EXACT error message you get?

Also, what happens when you try a different browser (firefox, opera, safari, chrome)?
