Hi, I just installed a new ATI Radeon 8500[128MB] video card and am now experiencing freezing with the error Out Of Range 23 kHz 37kHz. Sometimes the error appears at other times I just get a black screen. This happens while just browsing the internet, no games. I have tried changing the display settings, screen resolution, refresh rate and increasing the DPI. I have now reverted back to the original settings. 800 x 600 85Hz 96 DPI. Supported Video Modes are: 640 x 480 140 Hz 800 x 600 110 Hz 1024 x 768 85 Hz 1152 x 864 75 Hz 1280 x 1024 65 Hz Yet I am unable to get a refresh rate above 85 Hz. I also installed another 128MB of memory. Any input would be greatly appreciated. Thanks!! Kind Regards, Sarcha Specs in profile have not yet been updated. OOps I think I posted this in the wrong forum feel free to move. Thanks.
