My computer wont post. I just built a water cooled pc. I was installing windows xp professonal and I decided to go get some diner. I left it running while it was installing windows. I came back and the screen had a no signal on it. I tested another agp card and it still didnt work. I tested a PCI card and it still didnt work. I also reset the cmos. I still have nothing on my screen. When I turn on the pc I get no beeps the fans run and the run on my video card runs. Could it be that my CPU is fried. Thanks for your help.
