I should get my new gfx soon and I wanted to do a little overclocking experiment with my current onboard graphics. If I fry it will it damage the rest of my computer?
EDIT: Also, what programs can I stress test it with, does prime work for gfx?

Very unlikely that you'd damage any other components, but anything is possible (I once saw a robot burst into flames because of a divide-by-zero error). Simply increase the speeds until you start seeing artifacts on the screen, then back it down a bit.
A recent 3dMark bench would be a decent stress-tester. ATITool has a built-in OC/Stress tester.
I dont get artifacts, the computer screen just goes white and grey stripey, and its doing it at only 350mhz, am i going up 2 fast?
I think its using my system memory so should i turn up my fsb and ram?
Bugger 3dmark, 300mbs? I'm just gonna use the winamp fullscrean visualisations on high res.
Graphics cards in general typically don't have much leeway for overclocking without fancy cooling. If it's using system RAM then you'd get a small boost by turning up the PCIe bus frequency if your BIOS allows that. But it sounds like you went up too fast.
[Edit] Duh, sorry, forgot this was onboard graphics. I have no experience with that, but increasing memory frequency might be worthwhile.
400mhz and counting. Its better than I thought.
it shouldn't kill your computer, only at most crashing.
You can overclock but do not try to overclock the memory clock.
The best way to test overclock is to use 3DM0x, for onboard 3dMark2001SE is probably the best choice. Usually 10 loops of graphics test is enough
white and grey stripey is artifact you know
oh
It always used to do that without an overclock and sometimes when i start up again it a send error report thingy sez it was a stop error.
how about we call it a pinstripe error :)
Agggh! I just looked in task manager and winamp is using running 100% of my cpu solidly even when not in fullscreen, is this an error?
Okay, its at 500 now. this cant be right. I have a 80mm fan blowing on it but i should feel at least a little bit warm. Is SysTool reliable in that way? Could it be reporting wrong?
That is why you should use 3DMark for stressing. That way you can see if your chip is really faster than before or not.
I used a couple of other programs to check (everest, sandra), they both say its right. I cant be bothered to download the files now, I'll do it tomorow. It went up to 560 before it crashed and I've left it at 530 just to be safe. Its a shame I couldn't get a 200% increase (only 40 to go). I still think thats pretty amazing for onboard graphics on a £50 motherboard. It can now run Oblivion with 4x aa mid fade settings, full view distance and 1024x768 res at ~15fps. I dont know why I bothered getting another one.
If that's stable that's actually pretty impressive.
