I am having a problem my pc is working but when I power on my monitor there is no signal even there is no lights on my keyboard(backlit lighting), I haven't connect any gpu(I'll buy it later), so there is nothing about gpu. I tried ram slot change, lithum battery. after that I tried to turn on my pc but not worked. what to do? everything is well connected btw my motherboard is asus b150 pro gaming aura, one slot ram, this happened to me after I cleaned my pc, my pc is not very old, it's just 4month

Does the monitor display a "No Signal" Logo or Message.

If not, check that it is actually getting power and is turned on

  1. untick the above answer because you prolem isn't solved.

  2. check the monitor cable connection at PC and monitor - if appears OK try removing and refitting the graphics card and retry to get a signal on boot.

When you cleaned your PC, what did youactually do. It sosounds very much as though you disturbed a connection somewhere
