I think I overclocked my GPU a bit, erm, too much

[Dexter7]

Someone smack some sense into me!
Earlier this morning I was messing around in the graphics section of the power part of the AMD VISION Engine Control Center. I must have slid the memory or graphics bar higher than the defaults and my computer froze and I had to restart, then when it turned back on something similar to what is happening in this video happened.

Then I restarted in Safe mode, then I couldn't access the CCC. I also tried using the integrated chip, but that didn't work either.
Please help!

What was that doughnut thing? Was that what you were seeing? Or just the artifact rays coming off the doughnut? That looks like some kind of overclocking utility. How hot does that card get and do you use some program to ramp up the fan speed? I think Riva Tuner will work with ATI cards.

Shut down the PC. Leave it to cool, see if it boots in an hour. When you tried the onboard, was the video card still installed? And did you change settings in BIOS back to the onboard?

Installed such as inside the actual PC?
I don't want to risk breaking something if I take it out.

OK, if your motherboard has onboard video, there should be a setting in BIOS called "init display first" this will be in the Integrated Peripherals section. Change that to the onboard instead of the PCI-E slot. You also have to change the monitor connector in the back from the video card to the onboard video.

And, yes, installed inside the PC.

I'm pretty sure that the drivers for your card won't be the best ones for the on-board video chip, which may cause other problems.
You might have to "properly" uninstall the video card drivers and install the on-board chip drivers (should be included with the MD drivers).

(should be included with the MD drivers).

Would that be Motherboard Doctor software on the motherboard disc?

That should have been MB, not MD.
The MotherBoard disk. The doctor thing is probably just a repair disk. The drivers would most likely be on the MotherBoard disk, that is - if you have two different disks.

That would be FurMark, a benchmarking and stability testing utility for use after overclocking. As for the whole situation, it looks like you may have fried the card. When overclocking, make sure that you only move one slider at a time, then check for stability. From what you were saying, I find it strange that your computer froze, and the you ended up frying the card just like that. I have had my computer freeze up while Stability testing in MSI Afterburner, but then restart with no problems. Perhaps some other settings besides just the Memory clock were too high. That looks like a Graphics core clock problem to me. Also, were you using an after-market cooler on your GPU? If not then I wouldn't suggest putting settings up too high, or it will overheat. How long had you been overclocking?

Ed's right about changing from the video card to the onboard. You will have to uninstall the current drivers for the video card, I recommend Driver Sweeper: http://phyxion.net/item/driver-sweeper.html

Since you have an ATI card, tell DS to remove all those drivers, BUT, make sure it's just the video drivers. If you have a motherboard with an ATI chipset, you can mess things up very easily. Then install the drivers for the onboard. That way, at least until you get another card, you can use the PC. Onboard probably isn't gonna run RW very well, if at all.
