comp some times won't start

[John]

Hi all, some times when I turn on my computer, it shuts right back off
again, like in a half second, doesn't even get the fans up to speed, other
times it goes a second or 2, doesn't check the drives and beeps twice and
shuts off. Other times still, most times in fact, it will boot and run all
day with no problem at all. It seems like when I first start it in the
morning when it's cold is when it most often won't start, cold I mean maybe
69 degrees in the room. Is this power supply problem? or something else?
nothing's even getting a chance to heat up. Like I say, when it does start
up it will run all day and it's not doing it all the time. 4 mornings though
in the last week it's done that to me.

It is a hardware problem, of that there can be no doubt. But which
hardware component?

There are two ways of fixing this problem:

1. Start replacing core components (power supply, motherboard, CPU,
RAM) until the problem goes away. At that point you will know that
the last item you replaced was the culprit.

2. Wait until the problem gets worse, and the computer won't boot at
all. Then it should be easier to identify the dud component.

Good luck
