Most likely cause is a dead CMOS battery that holds the computer's configuration.
Most computers today use a replacable button cell that is clipped in a holder on the motherboard.
Let me know if you need more.

its only 5 months old, how could the battery be dead, could that also cause the computer not to turn on sometimes??

juggernaut,
It is possible, but unlikely, for a 5-month-old CMOS battery to be dead.  It won't cause the computer to fail to turn on though.
Tell me about the computer and it's installed components.
(Manufacturer, CPU, RAM, drives, etc.)
Have you recently installed any new hardware or programs?

When you say the computer won't "turn on", does that mean nothing on the display, or nothing at all happens? (Power LED lights, fans, drives spinning, etc.)

Try this:
Unplug everything except the keyboard and power cord from the computer. (Mouse, speakers, printer, phoneline, etc.)
1) Is it completely dead, or only occasionally?
2) Do the LEDs flash on the keyboard?
3) Any beep or series of beeps from the internal speaker?
Answer these, and if we need to go further, let me know if you are uncomfortable about getting "under the hood".

I wouldn't be too hasty yet.
First, I don't think the keyboard will beep......
But the LEDs on it should flash during power up.
Next, let me know if you are uncomfortable with "getting under the hood" before trying the following:

Open the computer and remove everything from the motherboard except the speaker, CPU, minimum amount of RAM required for your machine, keyboard, and the video card.
That means EVERYTHING! (Modem, soundcard, I/O cards, etc.)
Only cable from power supply used for this test is for the motherboard's power.  Remove all others. (Floppy & hard drives, CD-ROM, etc.)

Power on the computer.  Listen for beeps, watch for LEDs flashing and let me know the results.
