i`m using gforce fx5200 agp 8 card. working fine. until.been playing Asheron`s call 2. pci card, same specs gave up the ghost. so got the agp version. now sometimes it crashes and get the error, nv4_disp.dll-address bfaa. at which point it resets and can`t read the whole error.This can take minutes or hours before it happens. using the latest drivers and have now underclocked the card. still happens. any ideas?
