ATI Display driver stopped responding and has recovered

Hello,
I just bought an Imac and am trying to run Windows7 through bootcamp. I am having the same trouble with my drivers as many posts in Windows 7 - black screen and freeezing and little blue squares everywhere. However, I have no clue what these threads mean. What should I do? Any help is appreciated.
The message claims that I have an ATI Radeon driver.

At first I thought this was a Imac problem. I am glad to find out that it is a windows 7 problem.
Thanks!

I have an Ati HD3870 and had the same thing, black screen, freeze.
Tried everything, newer/older drivers, bios, motherboard drivers, switch Aero on/off, nothing helped.
Then i thought, if its a TDR problem, and win7 not tolerate any hicups in the GPU, i may try to downclock it a bit.
So i opened CCC and set GPU clock from 777 to 750MHz, and ram clock from 1126 to 1050Mhz. And voila problem gone!!!! I could play for hours and no problem!!

Oh man, thank you so much for this! I was totally pissed at my 4870, I thought it finally died since I have had lots of problems with its VRM (voltage regulator mod) because of inappropriate cooling by third party coolers. Not a single game could run for more than 2 seconds, then my screen went off and I got that error. I had almost dumped this one and get a new one. Now I underclocked it all the way down and it works, will experiment with the highest stable value. Thanks.

hey i'm also receiving the same error message while seeing a movie or playing games. i've read all solutions, nothing works for me though.

SYSTEM

CPU : Intel Core 2 Quad Q9400 @ 2.66
Motherboard : ASUSTek P5KC
Memory : 4G DDR3
Graphics : ATI Radeon HD 5770

I've installed all the latest bios,chipsets,drivers etc etc etc, but since i didn't get the same error couple of months ago, i just tried it with my old graphics drivers, but still, the error remains! Any ideas or news?

I fixed this problem a while ago for me it happened to be a bad ram stick

I have 2 systems an Intel I7 that works fine with either my Gforce 580 or my ATI 5870. I just built an AMD 1100 6 core and with both vid cards I get the "display driver stopped responding." Have tried virtually everything including sending my Gigabyte 990 Mobo in for repair. No probs found. Now Im going to try what TheSproutKing recomends. Or the AMD is on the scrap pile and back to the I7 860.
