hi there, I have a power issue with an acer 5742.  it can be on one moment fine, then the next it will power off, then when it's turned back on you get nothing on the screen and the blue power light slowly flashes on and off. have tested the hard drive, all good, have replaced the i5 cpu with another and the same thing. have also replaced the power board switch. any idea's? thanks
