My Dell Inspiron 620 is a year old and now it will not turn on. The motherboard light is on inside, on the outside the power button flashes an amber color. In addition, the light on the back is blue. When I press the power button, the amber light just flashes on and off on the power button, fan turns on and off, and sounds like it is going to turn on but nothing shows on display nor does the computer turn on to full power.
I believe it is my PSU because I have not turned it off for a year ( only about 11 times have I turned it off ) and I typically leave it on sleep mode when not in use.
Anyways, I want to try switching the PSU but cannot decide between the two:
