Your description points to a hardware problem. To figure out which component is causing the issue, do this:
1. Disconnect all internal cables (hard drives, CD, USB). Leave BUS power from the power supply connected, as well as the thin wires that go to the power button, LEDs, etc.
2. Remove all PCI/PCIE cards (except Video if not on board)
3. Remove all memory sticks except one.
4. Power up. If the problem still happens, replace the memory stick, and test again. If the problem still happens, you need a new motherboard.
5. If the problem is gone, start adding the components back and connect cables one at a time, until you find the faulty component.

Hello, It says "no boot device available, strke F1 to retry boot" ,when F1 is pressed the same message reappears.

Okay, got it. So this means the computer cannot communicate with the hard drive. The most likely cause for this is is a failed hard drive (though it can also be a problem with the drive controller). The first thing I'd do is replace the hard drive, and see if the computer recognizes the new drive.
