Better technicians don't shotgun. Swapping power supply
only on speculation is how the naive use whims rather than
facts. With a 3.5 digit multimeter, determine power supply
integrity in less than two minutes. Those with basic training
determined power supply problems without doing shotgun
surgery.
Two previous discussions described how it is accomplished.

Where would I apply special attention for your symptoms?
Maybe on numbers from red, orange, and yellow wires. Numbers
must be in upper 3/4 limits from charts. But with so little
information and without important facts from event logs,
device manager, and comprehensive diagnostics, then one can
only wildly speculate what may be problematic.
If you think for a minute that symptoms can define a power
supply as defective - especially without numbers - then I have
a good deal for you on a few East River bridges. Get the
meter that is so inexpensive and ubiquitous as to be sold even
in Sears, Home Depot, Lowes, and Radio Shack.
Many defective power supplies are sold because so many don't
even know what a power supply does. In simple terms, if it
does not sell for about $65 full retail, then it is probably
missing essential functions. If a full page of numerical
specs are not available, again, it is being marketed to bean
counter types who claim to be computer experts. Some
responsible manufacturers have been listed by others. You
really don't need even 300 watts. But again, so many 'bean
counter' supplies that claim more than 300 watts cannot even
output that much. A problem that does not exist with power
supplies that provide that long list of numerical specs.
It makes no sense to spend money on power supplies only on
subjective speculation. First get the numbers and other facts
from the event log, etc. Only then are you ready to define
the problem - or as for assistance.
Problems so often characteristic of power supplies are also
characteristic of failures on motherboard, power switch, sound
card, video controller, etc. How many things do you swap
before you have bought a whole new computer? Get the meter.
First obtain facts with numbers. Don't shotgun. Car
mechanics and medical doctors would be called scam artists if
they shotgunned. Why would you then make the same mistake?
