Well I had a perfectly functioning computer that I was going to throw into my car. I took it all out of the case, and now when I power it on it does not show anything on the screen and doesnt appear as if it is booting up? Both the cpu fan and the other fan are both running, the light on my cd drive turns on for a few seconds, but then nothing. Im not really sure whats wrong with it. But I have one idea what it might be. On my motherboard there is a little blue rectangle with white switches on it numbered 1- 8. Currently only the first one is switched into the on position. Could it be possible that any of these switches may have been switched to off by accident and that this would cause my computer not to boot? And if so, what should they be set to?
