Hello there!
I am facing a huge problem with my system.
I have a GIGABYTE B250M-DS3H and a Pentium G4600 (kabylake) in my system. Yasterday I installed a new graphics cardy, the GIGABYTE GTX 1050 2GB and after I installed it I turned on the computer and the POST speaker was making 5 short beeps and no image was displayed (Had a HDMI cable connected to the GPU) Then I turned off the computer and tried to turn it on again by connecting the HDMI to my motherboard. When I pressed the power button nothing happened, no fans spinning, no lights turning ON on the case or any components. My PSU is properly plugged in, even tried replacing the PSU cable that goes into the computer. I tried the screwdriver method, to see if the small power connector going to the button was broken, still nothing worked.The weird thing is if I plug in a mouse to the computer USB with LED lightning the lights do work so i think electricity is still going thru the motherboard so I know the PSU isnt broken.
Im really trying to fix I looked thru a million forum posts but nothing.
Thank you for reading this thru. I hope a few of you computer specialists might be able to help me out.
