So i changed my CPU from i3 to i5 but now the monitor wont turn on.
Before i changed the cpu my pc worked fine with the i3 after i changed it i can only turn on the pc with integrated graphics. But when i put the GPU in other PC it works just fine dont know why.
 
Solution
Without list of components, I could only guess your new CPU requires more power then old one, and your PSU is just not giving enough to run both new CPU and GPU.
