Entire machine freezes

[Doktoor]

This only happens while playing EQ.

It happens more in certain zones.

I have to hard boot to reset machine.

Happens completely randomly.

Happened on old VZTZ server that recently went down, but less so on P1999 which is why I quit over there several months ago - was unplayable.

Happens less on P1999.

Some of the zones I notice it more in include Unrest and EJ. Less in Karanas.

Help plz. Everyone says my machine is over heating, but I can hard boot and play just fine again - and it doesnt happen with any other applications or if I run my machine for days.
