Hey gals n guys. I'm new to this forum. Have a problem. My wife's PC won't start up. There is power to the MOBO as there is a green light on it when the mains are plugged in. However, when i press the power switch 'on', the processor fan turns for about half a second before stopping again. Nothing else happens including nothing coming up on the monitor. Have looked around the inside for any loose cables etc...but everything seems to be fine. Would anyone have any suggestions on what i could do? Could a weak MOBO battery be a cause of this? Wife is freaking out a little cause of her work stuff on it and would REALLY appreciate some help. Thanks in advance.
