I did a clean install of 12.04 in about August 2012, but Chrome gave me problems - about one in four links gave me the "snap" page.

I switched to Firefox, and it's been crashing several times a day. Finally today it crashed and won't reload - I just get the dialog to send an error report and restart. It's the latest version, which I think is 19.

I suppose this must be a fault on the hardware - I also get random system crashes, mainly "unable to handle kernel null pointer reference" which is bit beyond my experience, although I have googled it etc.

I know the video card is rubbish - ATI Xpress 200, but could this cause the problem? It's a Celeron D, so I know that's quite old now.

TIA for any advice!
