I have a Radeon x1650 Pro AGP (http://shop.ati.com/product.asp?sku=3122115), and I have been trying to use ATITool (http://www.techpowerup.com/atitool/) to increase the core and memory clocks, but whenever I make a change (even if it's just a couple of MHz), my screen goes black and stays that way. Then I reboot and everything's fine. Is there something I'm doing wrong?

Also, I currently have my desktop extended onto a second monitor which is plugged into a second port on my GPU. Would that be causing any issues?

BTW, if it's something really obvious, please don't flame - I admit that I am a n00b at this.
