Question memOk blinking red; no boot

[sams999]

hi so my pc just stopped working out of nowhere and when i turn it on it turns off 30 seconds later and i don’t know why. The memOk turned red when i turned it on. I tried repositioning the Ram and tried to pressed and held the memOK button but it still didn’t do anything. But i tried unplugging the graphics card from the power and the PC stayed on but it still didn’t show up on the monitor and it keeps saying no signal so idk if that has anything to do with it. again it happened out of nowhere so i didn’t drop it or anything it’s just weird

The PSU is a likely culprit.

However more information is needed.

Update your post to include full system hardware specs and OS.

Be sure to include PSU: make, model, wattage, age, condition.
