Sounds like your PSU has failed. That or your motherboard but that would be less likely. Especially such complete failure. What brand/model/wattage is your PSU?

Replace it and see if it works again. Your system is fairly power hungry so you need a good quality PSU to power it reliably. One should always have good quality PSUs but especially with more power hungry stuff. Rated wattage means nothing really, quality of components (capacitors, etc) matters most and you need good quality and enough wattage. It could be that your PSU couldn't cope with the power draw.

Well that sounds good but the 80 plus ratings aren't a guarantee of quality and there's also cheating going on with it. Do you know the brand and model?

You'll need to remove the back panel then to see the PSU. That's very easy and safe. It should be attached at the back with some thumbscrews. Simply unscrew those and slide the back panel back and it'll come off. Replacing a PSU is also not that difficult and you need just do a web search for it and you'll find all the guidence you need. Or maybe you could get a friend to do it.

What's the board's light label ? It should be named CPU, RAM, Graphics ("VGA") or Boot

Do the fans spin and light up (if RGB) ?

Sometimes is boot sometimes is cpu

Hmm then I'd rather suspect a CPU or BIOS issue than a PSU problem...

First reset CMOS

Reseat RAM sticks, using only 1 to start with

Use the board HDMI for video, remove the GPU
