;( I have an Evo N600c Notebook with a P111 1GHZ 512MB RAM 20Gb Hdd and a 16 Mb Radeon video card . Here's the problem I can run driver flawlessly for hours then when I'm into Castle Wolfenstein as soon as the sound gets intense it will lock up solid then i get the device failure when I reboot. I have the current chipset from Intel the current video drivers and the current sound drivers from Compaq. I have tried the Refresh rate tweak any suggestions?
