Hello.

Sometimes I was just opening a new tab, sometimes I wasn't doing anything at all.

I have followed all your steps above, but it tells me that Firefox will take at least 24 hours to notice the graphics cards updates?

Since doing these updates it has crashed twice.

These are those reports:

Did you download the current full installer for your Rapport programs and run them?

Thank you,

Yes I downloaded the installer and used it to update Rapport.

I haven't really been using the PC today but it hasn't crashed when I got back!

Fingers Crossed.

If Rapport causes any other problem, disable it's add-on. Then contact their support.
