I have a desktop that, on pressing power button, it starts up, but after a
second, it shuts down. I may need to try this a dozen times before it
actually boots up. (once actually boots up, it works great)
The desktop is 6 years old (but works great except the above issue), with
Intel Q9300.
I am thinking possibly either the motherboard, or the power supply, is
having some issue. But can't decide the exact reason (or maybe it is related
to other reason).
Thanks! | l********r

Yes, tested the main board battery, it is 3V during the whole time.
And yes, motherboard has not much dust.
Also tried another power supply, same issue.
So I guess the motherboard is bad, unless I missed anything.
Thanks everyone! |
