When I press the on switch it doesn't even load up the boot up screen.
The PC just goes onto a cycle of off and on, the system fan spins and and the green leds ight up( which is normal), then it switchs off and then on, continue with the green leds and fan spinning, the goes off and then on again fan spins leds lights up and then off etc.... In a loop.
It just suddenly happened.
No I have not changed anything.
