Hey, I can't boot my computer anymore and can't get into the BIOS either. I have done the standard BIOS over clock thing on the 1st of 5 levels which are said to be safe.

- can't get into BIOS
- keyboard doesn't respond
- white cursor on black screen, no splash screen (that could also be because the monitor takes too long to turn on though)
- the usual "everything is okay" beep still beeps as usual

What I've tried
- remove all devices except for one slot of ram. No GPU, no USB devices except the keyboard, no hard drives except the boot SSD
- reset BIOS via pins and via battery
- switch ram (though I'm not completely sure whether the test ram is OK)
- its NOT the PSU, I have tried one from a working computer.
- its probably not the main board itself either because it obviously detects the ram and beeps a lot if there is no RAM

Other than trying another main board, what can I do here? I'm pretty confused because I've exchanged almost all parts except the motherboard at this point.

Hardware:
- Intel i5 somethingK
- main board z97p d3

Thanks for the suggestion, I just worked through the whole thread. Please see my updated post, its not the PSU and the main board does detect when ram is missing.

Well it seems I'll have to get a new one then. I did try another monitor, but I'm seeing a cursor, so I'm guessing that's not it. Question though: why is it that everything is spinning and beeping correctly if the main board is broken?
