Thanks stones.
But what I don't understand is why my card is overheating now. I only had the HDD changed. Before I had no trouble with the card. I played 50 hours of Oblivion and everything was fine. 
Thats the wonderful world of electronics for ya :-/,
I figure that maybe the fan is getting weak and not spinning up like it should, those factory installed cooling fans have a pretty short lifespan (as little as 6months) the fan can die slowly without you noticing utill things get critical.
my vid card died last week from temp problem even though I kept the core at a frosty 44c (case fan secured to passive heatsink) the ram still went to crap (most likely the voltage increase given in bios, core and mem clock was default).
One thing to note about video cards- They hate all and any advice you recieve from the people at futuremark forums as it usually causes them an untimely death, keep everything as the manufacturer recommends and give it as much cooling as you can. A good score on a benchmarking program means nothing if your video card cant play video games because it is damaged (my little rant).
