Open the case and verify the cpu fan and hard drive fan is connected to the motherboard fan headers. Also your keyboard wont work because of that error you see. Is it a USB or ps/2 keyboard?

No offense to him but I doubt he can do this...
 
So is it working now?

If not, then if you can dig up a PS/2 keyboard (and providing you have a PS/2 port on your motherboard), go into the BIOS and enable USB or Legacy USB. That should enable your USB support.

And then as John said, open up the case and make sure that the CPU cooler and the hard drive fan are both plugged into the motherboard and are both spinning. Remove anything which might be preventing them from spinning.

If they are plugged into the motherboard and spinning, I would reset your BIOS/CMOS by using the reset jumper on the motherboard. You may need to resort to your motherboard manual to find out how to do this.
 
Great,
I can't try all this solutions, tomorrow I will in the work. The question is why it happened suddenly before the PC is ok?!
