PC not turing on after randomly shutting down

[TheFerretRanch]

I was playing some game on my pc, and when I was finally hoping nothing would go wrong with my day, things went downhill. My PC decided to instantly go dark and won’t turn back on again. The motherboard boards light is on indicating it has power but unplugging the cable several times, jumping it several times, and unplugging all cable and putting the back together couldn’t fix it. I don’t know how to solve this problem and I need help solving it, please.

Forgot to mention that I tested the PSU and it worked fine

Can you at least give us the make and model of the motherboard so we have something to start with.

Also I can’t check the temps as I can’t turn it on, but It might be getting a tad bit hot

Going by the motherboard is this a business computer?

Try and clear the RTC
Make sure to touch a bit of metal to earth yourself .The computer case should do.

The PC didn’t boot up at all, and still the motherboard has its light on

You reset - put the jumper back to where it was = no boot.
Did you try the 2nd step, remove battery and reset? 2nd last paragraph on instructions above.

Which games do you play and are they up to date ? The way you say the pc just goes dark may indicate the psu ..
