When I turn on my pc, it beeps 6 times and my monitor says no signal, there is nothing wrong with my monitor but I’m unsure with what’s wrong with my pc, any ideas?

Replace the size 2032 CMOS battery. A low battery can cause all sorts of bizarre problems. They last around 5 yrs. and the 780 goes back 10. If by chance it doesn't work, it's still cheap. Remember to unplug PC anytime working on it.
Are you using a graphics card? Remove it and use onboard graphics.
Problem still the same? It's either the PSU or MB, may be more likely the MB? Without being able to run diagnostics from here like what a computer shop can, it's a little more difficult to pinpoint. Without it giving you a different error code, like with lit up numbers on the front of the PC, it's sounding awefully dead.
One of our other experts may even have a couple of other tips.
