Hi, so lately I have been having this problem which occurs when I leave my computer idle without working on it. The problem is that I get back to my computer, turn on the screen and I find my Windows 7 crashed and showing the Blue Screen of Death and showing file "atikmpag.sys".
I have only had this problem for a week only, it never occurred before, I haven't installed any new hardware or software lately.
I tried uninstalling the driver and using Driver Sweeper to remove the AMD driver and then reinstalled the latest Beta driver from http://amd.com/
This doesn't occur when gaming, since I play DotA 2 for hours and this doesn't happen.
I have no idea, but, someone on the Microsoft forums had a similar problem with their HD 5870. He suggested upgrading the BIOS to your Graphics card. Reference
Sorry that I can't be of more help.
Yeah read that, I doubt its something to do with the BIOS since it was all good except for this week.
By the way, the temps are stable (less than 30C) and the fan is working with no problems. The computer can stay up 24 hours if I keep working on it, but if I leave it turned on and step away for a few minutes I get back to see Blue screen of death taking all over my monitor.
Hm.. I'm sorry, I'm not sure what else could help.
I was reading other forum posts about the same issue, and at least one mentioned that using onboard graphics with dedicated graphics causes bandwidth issues.
I'm sorry, I can't help any longer, I just don't know what the issue is, as I said in the original post.
