PC fans spinning, led's on and GPU working but doesn't boot.

[Breenocoelho]

My computer was working well until yesterday, today I woke up and when I was going to turn it on I noticed that when I pressed the power button the leds on the keyboard and mouse doesn't glow and show nothing on the display but the whole computer is (technically) working. What could it be?

And the beep sound that usually have is gone too. Someone help please.

My Computer specs:

EVGA GeForce GTX660
Corsair Vengeance Blue 8 GB (2X4 GB)
Rosewill 750W 80 PLUS BRONZE
Intel Core i7-3770 Quad-Core Processor 3.4 GHz
ASUS P8H77-V LE

Sorry for bad english, not a fluent speaker

Have you tried clearing the CMOS (unplug the power cord and remove the CMOS battery for a minute)?

It worked, my computer is about 4 years old, do you think that I need to buy a new CMOS battery or I can keep up with that one?

I'd say to leave it like that and, if issue occurring again, changing the battery.
