I have a computer of a friend where there is no video when it starts up. He thinks that it has a virus on it but I am not able to see as I get no video capability on any of my monitors. I have reset the cmos by changing the jumper on the motherboard but with no success. I removed the ram to get a beep code but it produced no beep of any kind. I have cleaned out the dust that was found in the computer and that has not helped. I tried starting the computer with a Knoppix bootable CD but got no response. I tried bypassing the integrated video chip on the motherboard with a pci video card but with no response. I think that the cpu is fried but I am not sure as I do not have another one to replace it. Is there a way to test the cpu as it is? Thank you for your help on this. Please email me at <snipped> with any solution and comments.
