System unit on desktop won't power up

Specs: Windows Vista
Hi my system unit on my HP desktop won't power up at all. Over the last few weeks the computer would just automatically shut itself down after about 15mins or 20. Now the unit won't power up at all and there will just come a flash of light to the power button. All the plugs are connected..anyone have any idea what the problem could be??
