Ok, so occassionally when I get on my computer I get the "blue screen", but here's the catch, the only time I've blue screened is logging on to PB, what would cause this?

sounds like it would be a memory (RAM) overload.. probably have to much shit running and when you use your interent browers your causing your hard drive to use virtual space and act as your RAM.. this puts stress on harddrive and causes it to crash.

I've been getting a Norton warning saying that I have a high CPU usage, but I also play other RPG's so I don't know y it singles out PB, usually when it happens it is the only browser open.
