Checking your PSU so easy a bunny can do it.

You will need 2 things.

And something like this which I got for $2 at harbor frieght.

First you will have to open your case, usually by 2 screws. Like these.

Now turn on your volt meter on the settings shown below

Hook up the leads into the 2 connectors

Turn it on, and touch the leads together, to make sure it still reads 0.000

Good, if it doesn't return it, and now take the molex connector.

Insert the black lead into the black cable

Now we will measure the 5v rail
Insert the red lead into the red cable in the molex.

Obviously the closer the better. To the 5v rating.

Now move the red connector into the yellow wire, this will test the 12v rail

You should get a reading within 5% of the 12v range.

Now put it under load with a program like 3dmark, and retest, you should not drop much at all if your PSU is good.
Mine dropped to 11.91 now test yours!
Now you should get a reading within 5% of 5v.
