I recently updated the PC I built which had integrated graphics with a dedicated graphics card ( GeForce GTX 1050 Ti SC). This upgrade went fine, a week later I upgrade the CPU from an Intel i3-3225 to a Intel Core i5-3570. The install seemed to have went smoothly but when I turned on the PC I get a blank scree. The fans include the CPU fan all turn on, their is no indication that anything is wrong but the computer wont boot. I tried placing the i3 processor back in to see if it was a problem with the i5 but now that processor wont boot either. Any thoughts on what the issue is or how to best trouble shoot it? Thanks.
