ask some electronic technician friend to check out the capacitors of the cpu card. There's also a component in the motherboard that usually dies, ask mr Brana about it on IRC. You could also try out another PSU.

I think that having various browsers would be good as sometimes one browser refuses to open certain page and the other opens it without problems. I know people who never uses Firefox and other who can't live without it... it's a matter of personal preferences I think. I like Firefox and I think that even if the port is more cpu hungry than OWB it may be useful.
Fab has done a great job with his khtml browser and he's improving it each day more and more... it's the most advanced OWB port and I hope he continues improving it because it's a joy to use his OWB port.
