what is wrong with my pc?

[MxPikO]

greetings, since some days ago my pc just wont boot up. First, it shut down suddenly and when it turned up, a bios message about a bad setting making my pc to crash popped up ( my cpu is a 3570 non k and my board is a b75 chipset so, no oc). it booted again but then i started gaming and it shot down again, but this time it wont boot up. I've tried to change RAM from slot, one stick only, tried different gpus and all that stuff u do when your pc is not starting up. i have noticed that the pc turns on, not video signal and also my peripherials (mouse and keyboard) wont turn their lights on but the pc indicatora led will.
does it sounds like a bad PSU? im betting on that since is my oldest component , i bought it 8 years ago.
thanks for your help and sorry for bad english.

Usually people who paid the money to buy a good power supply will provide the make and model for their power supply when asking for help, you didn't. So it's an 8 year old power supply that is nameless...that makes me think the power supply needs to be replaced anyways. So you might as well start there.

all you can do if you have a volt meter is read the output of the power supply see if one of the legs is bad. if not i go get a good name brand replacment like seasonic 620w unit..
