check switch at back of power supply and make sure it is turned on and power supply is plugged in. have to cover that ground first.

test power supply. turn off power supply at back switch or unplug. open the case. unplug connector from motherboard (24pin) . jumper green wire and second black wire (to left of green). i use a paper clip. make sure clip is not touching the case. turn on power supply with switch at back or plug in. if fan turns the power supply is working. if not power supply is toast.

download manual for your machine to see what green flashing light is. is this light on the mother board? try removing ram and try them one at a time to see if it will post(power on self test) if you have no luck with that the problem is either the motherboard or the processor. the only way i know to figure out which is to interchange the parts with a known working one. you have to strip everything down to the motherboard, processor, ram, video card and keyboard. it is best to take it out of the case to eliminate any grounding issue with the motherboard touching the case where it is not suppose to. this is a bench test and i would try it before purchasing anything. others would search for an upgrade package to replace motherboard, processor, and ram.
