temps looks good , as for the logs its still the same , you mentioned you had the most *recent* version does that mean you had 84.21 which got released just two days ago? if not then give it a shot ftp://download1.nvidia.com//Windows/84.21/84.21_forceware_winxp2k_international_whql.exe , if you alredy had that 84.21 or after you tried it nothin changed then rma the card cuz as you can see at http://support.microsoft.com/default.aspx?scid=kb;EN-US;q293078 if its not the driver its gotta be the card
edit just noticed, on the screenshot i see you alredy had 84.21 , just rma it
