I cant access the internet..keeps saying internet explorer has stopped working?

[Sharon]

My sons computer has suddenly stopped working.

It is very very slow.
Everytime I enter something I leave the room and go and do something until it registers.

I cannot access the internet.

I cant do much at all...as everytime i try it comes up internet explorer has stopped working.

I have searched the net for solutions, but it just wont allow me to proceed.

It has AVG on it, but when I click on it, it comes up with internet explorer has stopped working.

I cant restore..same message

I cant open internet explorer.....same message

Any ideas on how to help a not techinal minded mum fix this problem
Thanks for the replies so far

it is a desktop computer
it is wifi access

I have tried starting in safe mode but still cant access the internet

I have tried shutting down and restarting

I have tried to restore it back to an earlier date...but same message keeps coming up

How do I use a different browser if I can get onto the internet?

thanks again everyone, I really appreciate your time
