Mac mini mid 2011 won't boot

This morning I found my Mac mini mid 2011 frozen. I shut it down by holding the power button.

Now it does not boot. When I turn it on I don't hear the usual chime sound or any other beeps. I can hear the hard drive powering on and the fan starts to work at full speed. Nothing appears on the monitor. No output signal at all.

I have tried disconnecting all cables, press power button for five seconds and the. Try to boot again. No luck...

Any ideas?? I loads of work to do and I am loosing hope. No apple stores in Greece to take it in...

Mac mini, OS X Mavericks (10.9.5)

I've tried everything including SMC rreset. No luck.

One other clue is that if try to boot up without Ram installed, it recognizes that ram is missing and beeps

so to summarize the symptoms:

1. Computer has power

2. No chime sound or any other beep when I power the computer on

3. Fan works at full speed

4. No output display signal

5. I can hear the hard drive powering on

6. The computer recognizes if you try to boot it without ram and beeps

It appears you have a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

The problem was in the motherboard. 3 different services said that it was unrepairable. I am managed to solve the problem myself with reflowing the motherboard. Baked it in the oven for 10 minutes at 180 Celcius... Managed to save 400 Euros that was asked from me for a new motherboard!

Did you have to remove anything fro the logic board before baking? I am asking in order to provide details for other Mac users with the same problem in the future.

I've only removed everything I could unscrew. I was luck not to damage the cpu or any other chip... I was also lucky not to have any cables or plastics melt... I think 180 celcius for 10 minutes is a good combination. The oven was preheated. Of course, I've left the logic board to cool down, before testing it.
