Many people think it is the power supply if the computer does not start,
but usually it is something else. Of course, it can actually be the
power supply, but when you hear beeping, then that decreases the
likelihood that it is the power supply.
Here is a link for a simple power supply test.

If it fails this test, then the power supply is bad. It could be bad
even if it passes this test, but the probability is that it is something
else.
Be very careful not to touch anything inside the computer, and under NO
circumstances should you get into the power supply, as there are
dangerous voltages in there!
Unfortunately, there are many things that could cause your symptoms, but
bad memory or a bad motherboard are the most likely. Take all your
memory sticks out except one and see if it starts. If it does not, then
exchange the memory stick for another and see if it starts. If both
sticks fail, then it is beginning to point toward the motherboard, but,
as Russ said, the beep code might tell you what the error is.
Hope this helps! Good luck.
