HI all, i have a problem with my daughters pc.
Siemans desktop pc. On starting it immediately and continuously powers off and on. other than the sound of the processor fan turning on and off there is no other obvious activity. The monitor does not come out of standby. The f1 - f12 functions have no effect. The on/off switch has no effect. Power can only be shut of using the switch mounted at rear where power supply is inserted. There was no obvious time at which this happened, just went to turn it on and problem was there.
Your views much appreciated.
