Could be a bad psu, bad mobo, or bad cpu. If it's just straignt power on and off it's probably a bad psu (power supply). If it's randomly locking up and having trouble not coming back on as well as power cycling then it's probably the mobo or the cpu.

What it does is it turns on it is not on for long than turns off is not off for long and than turns back on and it doing all day ..the computer techy at my work place is at lost has what is problem ..

replace the psu. If that doesn't fix the problem then it's either the mobo or the cpu.
