Hi, My computer wont startup when i turn the power on, it doesnt hear a beep sound when its turn on fully after like 10 tries it finally comes on. I dont know what the problem is

Power supply is probably failing. Also could be the on/off swith in the front panel of the computer.

Yes probably the button. I had a case that did that before, had to push it like 20 times before it would come on.
