It’s as simple as that. My tower won’t switch on. I’ve tried pressing the power button multiple times and nothing sparks into life. I have tried unplugging and plugging back in, toggling the power switch, but nothing is working. I haven’t had my PC switched on for a few days, I don’t know what the Hell has happened…
If you take the side panel off can you see any lights on the motherboard that would indicate that there is power getting to the motherboard from the PSU.
