Computer won't turn on.
Alright here is the problem, First off it is my little cousins computer. I hit the power button and just the lights on the fans turn on and the fans spin but not to full speed. This includes the CPU fan and case fan. The video card fan appears to be going normal speed. But also the lights blink and don't stay on. The computer will not post at all. I check to make sure the ram was fitted properly and that the video card was seated right. I also put my power supply in which is working perfectly and it still does not post. What else should I do next?
