...the red power light is on? I have a cisnet desktop. I'm not sure about the specs, since I'm not computer savvy. I'd left the computer on overnight. The following day, when I attempted to use it, I noticed that the screen saver was frozen. I used the power button to turn it off, since it was not responding to key input nor the mouse. When I tried to turn the computer on, it would not boot up. I can hear the fans come on, and the red power indicator light comes on, but to no avail. The monitor is working, but not receiving a signal from the cpu. I tried connecting the cpu to another monitor, and it still does not boot. One person has told me to replace my video card. It looks as if my video card is located to the back of the cpu, if this helps any. Any assistance will be appreciated. Thank you in advance
