I have a question. I took an old pc in order to upgrade it to my son, not something new but useful. I bought a new motherboard, AFOX H61 chipset and had a used but working CPU I-5 3570K. But when I connected the motherboard, the PC turned on, fans worked, but no beep at the beginning or anything on the monitor. of course I checked the monitor on ther PC and it worked and so the PSU, I tried it with a working one, of course. I really can't tell what's the problem. Can anyone assist here?
