More likely you have a manufacturing defect. Those who are quick to
promote popular myths will blame destructive transients. Those
transient occur typically once every eight years.
Decide whether you will analyze it - or have a professional. Many
first analysis steps are simple. Start with the foundation upon which
the computer is constructed - power supply 'system'. Note, I did not
say just 'power supply'. For this, a ubiquitous tools called a 3.5
digit multimeter is required. A tool so common as to be sold in Home
Depot, Lowes, Sears, and Radio Shack. In your case, the first voltage
measurement starts with the purple wire from power supply to
motherboard. Then the green and gray wire voltages must be recorded.
Purple wire must measure more than 4.87 when power cord is connected -
computer powered on or off. And what that actual number is should be
reported because the value includes other useful information.
The overall summary of what you are looking at - how those wire
voltages change when power switch is pressed, etc - is found in
previous posts:

Do not waste time and money replacing this and that. First learn
what really is wrong. Remember it's a power supply 'system'. Numbers
that you don't understand should be posted for further insight.
However if you are not going to start with the multimeter, then get a
professional to fix it. Numbers from that meter are important to fix
it right first time.
