I recently installed a new cpu. I installed it correctly along with the heat sink. When I turn my pc on everything works fine expect for the gpu fan which has a hard time spinning or doesn't spin at all. Then my pc beeps 2 two times and it powers off. I'm getting no input signal on my monitor. The monitor is perfectly fine because I had hooked it up to my laptop.
What kind of video card is it?
Is the video card fully seated in it's slot?
Does it have 6 or 8 pin auxillary power ports and if so are they plugged in?
What is your motherboard?
Do you have another video card? If so take out the new video card and replace it with the known good one and see what happens.
