Help me on this question.....

Hi guys....The "nvlddmkm stopped and recovered" error got so much to the point that i cant play any games without hitting my head every 5 mins....so i contacted Palit....My GFX vendor....They told me to record the temperature after running Furmark....It was the first tim i used that program....While running that app i noticed something peculiar.....Although my Card temperature rose steadily and wiggled at about 103 C....The power reading next to that was changing randomly like 19 w then 53 w....there was no steady increase or decrease but it was erratic....

My doubt is that is this normal or will there be steady increase in power as the load on the card increased.....Is my PSU the culprit all along????

System Spec:
Core i7 920 @ Stock speed
Mobo Intel DX58SO
Palit GTX 295
8 GB DDR3 (4 x 2 GB)....can i use it in this way?...read somewhere that it should not be so?
Cooler Master 850 W real power pro

Help me out on this....

All my games run at max temp 82 C....never seen the temperature above it under normal conditions......The 103 C temp is at maximum load on both Gpus....The cooling fan dynamically changes speed as load increses......Also the support suggested that i run furmark app in xtreme burning mode to check for card stability.....I think the card temps are all right.....im worried about the power....
