Blimey, thanks for the swift replies

. Just checked an i have all the latest drivers for my system. Running forceware drivers 158.18 for gpu (think they are latest ones, installed them on Monday

). Not running any temp warning software, oh did i mention my operating system is vista home premium? Got stuck with it as my old pc couldn't be repaired (best one i ever had) an they gave me this one for free, still working the bugs out of it spose it may have somethig to do with that. Think i'll put another gig of ram in anyways as vista uses about half a gig all by itself.
