So I have been having some severe vista issues lately. I will work online in firefox or even google chrome and walk away for 30 minutes, come back and windows will lock up. It will also do it randomly sometimes and I have to do a hard reset to get back.

I updated firefox just now to see if that helps but its also doing it in chrome and I just downloaded that two days ago.

I am going to upgrade to 7 on monday to see if thats any help. Doubt it will be since it will still be a microsoft OS.
