I had a similar problem see this thread Getting constant pop up "IE has stopped working"
for me it was fixed by uninstalling Avast!.
I did run sfc /scannow and it found integrity violations and fixed them. Running that certainly won't hurt and may take care of something you're unaware of. If you just want it to check run sfc /verifyonly, that will check for any problems without doing anything else.
You might look at event viewer to see if it shows something, maybe a repeat program showing every time you get the error.
