hi all, hope you can help. bought a used intel duo processor e6850. it still had some grey paste on it. so i asked the person i bought it of, should i remove it. he said if you put it back the way it came of, it should be ok. he told me how to put it back the same way as it came of. but do you think it would be better to clean it first. if so, what is the best to clean it with, and what is the best way to go about it ? do i clean the processor and the head of the cooler. regards gboy.
