Well, I have a HP Pavilion n465c - Frankenstein version. I call it that because I upgraded the HDD, the video card to an ATI X850XT, and boosted the ram to 1gb. Anyway, I took the ram out to try it out on a computer that I'm attempting to fix for a friend. I put the ram back and tried to start my computer but it won't start up. I took out the ram that I first removed and it still didn't work, I took out the video card, nothing. The CPU and tower fans still start spinning, I can hear the hum of the HDD and the fan on the video card still spins also, the light on the onboard ethernet still comes on as well. The CD drives open and close as usual. On the other hand, the lights on my keyboard do not turn on. (It's an eclipse keyboard with lighted keys) and my optical mouse doesn't turn on. My monitor stays off and there is no BIOS or any type of loading screen. Lastly, the motherboard hasn't given me the normal somethings-wrong beeps. When I plug the power cord back into the tower it all powers up automatically. No need to press the power button. Any ideas?
