hello again Preamble: i am having a similar problem to the one discussed in this thread: http://www.hardwareforums.com/so-tired-failing-drivers-ati-3650-512-pci-e-2-0-vista-colide-25094/ but i do not have the luxury of being able to go for an nvidia card; even if i did this card is too new to just chuck. Problem: -any time i start a game, it doesn't take long before my ATi driver decides to crash and force me to quit the game. (atikmdag.sys) -Also, when my pc is downloading a large file, or streaming a video, my DPCs get really high and max out my processor [i have already ascertained that this is also a problem with my ATi driver] Solution: my current Ati driver is out of date - version 8.612.0 - so i figured that an update to the current version (9.5?) would solve the problem. Problems Arising from Solution: i downloaded the current driver from ati.amd.com, but after installing and rebooting, it had not updated the drivers. so i uninstalled all my ati software - ccc, cim, drivers, reg entries, the lot; and rebooted before reinstalling the current drivers and rebooting again. this time, it was still showing as driver version 8.6! so i tried updating the driver available from MS update (last resort), and upon reboot, the driver version was 8.5 i rolled back the driver in device manager to 8.6 and tried reinstalling the official ati ones again, to no avail. Questions: is there anything i've done incorrectly, or am i missing any steps out? what can i do to resolve this issue? ----- i would be massively thankful for any advice here. ------ system specs: -CoolerMaster Real Power 520W PSU -MSI 790GX-G65 -AMD Phenom II 710 -Sapphire Radeon HD 4870 512MB -Corsair XMS3 1333MHz DDR3 6GB (3x2GB) -WD Caviar Blue Edition 500GB -generic SATA DVD-RW Running Vista x64 SP1 build 6001
New symptom guys (well, a variation thereof), i now can't even [ctrl]+[alt]+[del] out of the game when the display driver crashes - i now have to forcibly turn off the pc.
