Hi guys just wondering if any of you had come across this problem before. Recently my 8800gts has been causing/going into power saving mode, this can happen as soon as i power on the pc or maybe after an hour or so after boot. The nvidia system monitor (plus other hardware monitoring programs) report my gpu temp as spiking from 0c-94-128-192c every second also on the nvidia system monitor it show my mcp temp on the motherboard tab as 235c !!!. I've put in my old gfx card and the system works fine so im guessing it has to be the 8800gts, i've tried some (supposed fix's) from the internet ive come across i.e new thermal paste, bios flashing and so on but still this problem persists. Can anybody help please ? Thx.
