Radeon 7670m

you should try updating your graphics drivers at amd.com

good luck

edit: if amd doesn't have newer drivers (you can use their auto-detect feature) you can probably get them from Acer.

the card does not show up when i go to amd's website i had to get the driver from acer.

So you have updated your drivers?

Also, you can use AMD's "auto-detect" feature.

yes i have updated them and the auto detect feature says that it cannot detect the card

thats weird. If drivers are up to date then it could be a faulty card. I would call Acer and see what they say.

Also make sure you reverse any changes you've made to the laptop (changing hardware) because that's grounds for Acer to terminate your warranty.

you are not alone. I bought a brand new Aspire 7750G-6645 with Dynamic Switchable Graphics - 7670M. I have the exact same problem. Pretty much any game if i tweak the settings. Lara Croft Guardian of Light on any settings, Dungeon Defenders on above medium, and I just tried Diablo3 and pretty much on all settings it blue screens. I got D3 to work with limited crashes on lowest settings, and maybe none now that i did full screen windowed mode. I got the same error ("display driver has stopped working and recovered") as you if i alt+tab to windows and close program before it gets a chance to go to blue screen.

It seems impossible to update the drivers for these. I have the most current ones from the Acer website but they are not current. Right now I have CCC 2011.1013.754.12275 and AMD Display Driver 8.901.4.0000. I've contacted both Acer and AMD with no response. Also have sought help on forums and my bluescreen log shows the ati sys file as the culprit of blue screen. Auto detect from the AMD/ATI site doesn't work, and i've tried to find drivers there (latest i've tried is 12-3_mobility_vista_win7_64_dd_ccc) but anything there hasn't worked. I've also tried leschat 12.3. I've followed the guides and have run Driver Sweeper and followed steps before installing drivers, but nothing works. What a waste buying this laptop if the video card isn't going to work correctly. I could've gotten something 100-200 cheaper if this is the performance i'm getting.

please let me know if you find any solution.

finally found drivers that i could install:

http://drivers.leshcatlabs.org/2012/05/15/catalyst-12-3...

so far i've only played Diablo3 on these drivers for abotu 20 minutes, but they were stable for 20 minutes on medium to high settings, whereas on lowest possible settings i'd get bluescreens every 5 minutes before.

FYI I installed 5/14 Catalyst 12.3 UP2 UnifL for Hybrid Graphics, which "includes config updates from 12.4 and 12.x":

5/4 Catalyst 12.4 WHQL UnifL for Hybrid Graphics:
