Hello everyone. This problem appeared a week ago. Sooo... I turned my PC on and monitor says that there's no signal. I had same problem few years ago. Solution was simply removing my GPU and than installing it back.
This time it's far more complicated, so far i tested my gpu in friend's pc, it worked fine so gpu is not s problem. By reading some similar posts here I assumed that cpu or mobo might be faulty, since none of my friends have 1151 intel socket i couldn't test cpu, so i brought all together mobo, cpu and one stick of ram to local IT dude, he "fixed it". He told me something like "some pins oxidated on motherboard, i am not sure what that means.
However problem is not solved after installing mobo back into my pc. Some people online said that faulty psu can cause black screen/no signal. It made sense to me since psu is older than 5 years now. So i bought a new one installed it and guess what, black screen/no signal is still here. I'm losing it and i have no clue what to do anymore. I still think that cpu or mobo might be faulty. I would really appreciate some help.
My specs: RAM: Kingston 8gb ddr4 x2
GPU: Gtx 1070 8gb
CPU: i5 7400
MOBO: not really sure but it worked well for past 2 years.
PSU: ANTEC 750W EA750G Pro EC
