Hi all, I tried overclocking my 1gb HD4870, and my computer will constantly freeze/fan runs really loudly/restart/all of the above.

Now, if my signature works right, you can tell I have ample power for the card (750W), and ample cooling as well (my cards run at about 60C at full load). Any ideas as to what my be going on? I've been using CCC but I've been thinking of using Rivatuner. Also I get problems when I run the auto-tune utility as well.
