Computer won't restart if turn off!

[Ashley Benton]

Hi,
I actually completely changed the power supply twice (open the computer,
remove the old one and put and plug a new one) in the last month. The first
time when I try to install a second hard drive. After I installed the hard
drive in the computer I had to change the power supply because it didn't
work anymore. I was unable to configure the hard drive with Windows and took
it off, then partitioned my Windows hard drive. A few days later or maybe a
little more than one week I couldn't turn on the computer anymore. I changed
the hard drive and reinstalled only Ubuntu. Then I moved my computer. There
was blue light in the back and I had to completely change the power supply
again. The person who had changed it the first time told me that from the
series of three he had installed it was the second that broke.
Would I see it if the capacitors on the motherboard were leaking? When I
open the computer I don't see anything wrong or maybe I'm not seeing
anything because I didn't saw it before, but it seems to be the same than my
son's computer except not installed the same way.
Can I wait before to see a computer guru or will it become worse if I wait a
few months? Not speaking about it can stop to turn on completely or shut off
by itself, just the problem it apparently have and a risk to make more
damage to the mother board or anything else. Do you have any idea why it
turned back on when I changed the hard drive?
Thank you
Megan
