The display driver has stopped working and has recovered (ATi)

when I am playing games, such as Farcry 2, CoD:WaW: or Dawn of War 2, my screen will turn black and and my com reboots without a blue screen(after disabling the auto restart on error) sometimes I am able to alt + tab before the game crashes (such as empire: total war, the game will keep reloading the graphics when i am in game like its trying to reload the game once I am back in it will go into a loop and then a hard reboot of my com).

I am using an ATI HD4870 PCS+ by powercolor I've tried underclocking it but it wouldn't work it still happens. I am lost now.

No I did not overclock anything, I am using Thermaltake toughpower 850Watts and my card is at 49c -52c at idle and about 70c when playing games.

I've amped up the Fan speed to 100% for my Card and switch my casing fan to high and it still has this problem, I've tried the system config method too but failed.

some games like crysis or C&C3 works fine. thats what puzzles me..

I have that same issue with the 64bit Win7 and ATI. It can be reproduced by turning on hardware acceleration with flash and then going full screen for me.

Also some 1080p movies through VLC and fullscreen will cause a crash like that.

Everything bogs down, black screen and I have to hard reboot.

I can get the same problem with games if I have a moving playing on my other monitor and try to play certain games. Games like Champions online though that support pretty seemless alt tabbing work just fine, but something like Farcry 2 will cause a system crash.


Phenom II with a gigabyte board, but not sure if it is an issue with Windows 7 x64 or with ATI.

Same issue ;(!

I have the same problem here. I upgraded from windows vista 32bit to Windows 7 ultimate 64bit and the problem still the same.

My specs:
Laptop Toshiba Core 2 duo T9550@2.66GHz. 4GB RAM.
ATI Mobility Radeon HD4650

You know what i say about this? ATI never again! NVidia come back again, I forgive you!

I first played this game on a nforce 780i based card, the cpu is Q6600 clocked to 3.0GHz, I have 4 GB of ram and a Geforce GTX 295 GPU.

The initial try was on Windows 7 64 bit, the driver stops responding then restarts sometimes 3 times in 5 minutes, then the computer freezes, and I have to restart. I later installed Win Xp 32bit again, and tried both the newest driver, a beta driver even newer, and the older 182 drivers that worked for some. The game now freezes after 10 seconds of playing.

The best solution for me so far has been Vista 32 bit with Geforce 9800GX2.

That one worked for almost 2 hours before the first crash.

Same issue here, slightly different GPU

Running ATI HD 5770
Windows 7 Pro 64 bit (Fresh install, current updates)
i5 Processor
ASUS P7P55D PRO MB with latest bios
4GB Ram
NO Overclocking of any sort.

Brand new build - not sure if this is hardware or software...

Anyone find a solution yet?
