No POST or beep. Fans spin up. Nothing more happens. Dead PSU, Motherboard or CPU?

A month ago I updated my BIOS and the computer ran fine for about 2 restarts, then on the third I tried entering some menus, everything went black and that's where I'm at now.

The computer starts. Fans spin up, hard disks spin up, but it does not POST. It does not beep. No video shows. There is no interaction what so ever.

The only way I can get any feedback from the motherboard is to remove all the RAM sticks, then it will beep. Otherwise, nothing.

I have been in contact with ASRock support, they sent me a new BIOS chip to try after a while, because I immediately assumed the motherboard gave up on me. It did not help the least.

After having tried everything I can with the motherboard except for replacement, after having tried running with only RAM, CPU and GPU (Mobo has no video output), or only RAM and CPU, it gives me nothing. In case and out of case having the motherboard on a dry towel I'm not sure weather it is the motherboard any more.

The motherboard is about 1 year old, the PSU and CPU is 3 in August.

So I'm wondering, what can the source of my problem be and what is the best way to check each component? I have no access to spare components, unfortunately.

Motherboard: ASrock 970 Extreme3
PSU: Fractal Design Tesla 650W
CPU: AMD Phenom II 965 BE

Everything spins up, nothing more happen. No beep, no video, no nothing. I don't know what to do.

Today I got a new Gigabyte motherboard delivered, and everything works now.
It was simply the motherboard that gave up on me for some reason.
Everything is now back in working order.

Not touching BIOS updates in the future.

Keep away from BIOS update until you learn how to read the instructions and to use the update pertaining to your CPU and its revision number and the motherboard matches identically to your model and version.

The problem with later model motherboards is that they seem to require a bios update on occasion as with past motherboards pre 2006, they never need any adjustments.

The next time you feel a need to update the bios, ask in the forum first and whether it is a necessary action for the issue at hand.

Happy Computing!
