Computer stuttering/buzzing at random

A couple days ago, I accidentally hit the switch on my power strip, knocking out the power to my computer. After starting back up, I went to play a game on the computer, and the computer was stuttering. Each time it stuttered, there would be about a quarter-second in which the mouse wouldn't respond, the video would freeze, and the audio would turn into a loud buzz. This ranges in frequency from happening once a second to a couple times a minute.

I've found the following solutions elsewhere on the internet, and have tried them all with no success:

-Disable Windows Aero (I disabled Aero as soon as I got this computer, so that's not the issue)

-Monitor the temperature of the graphics card (it goes from 50C - 80C, but it seems to stutter just as much no matter what the temperature is).

-Update/reinstall the graphics card drivers (I uninstalled the drivers, and while the computer was running on the default/driverless setup, it was still stuttering, so I'm inclined to think it's not an issue with the graphics card).

Desktop: HPE-550f
OS: Windows 7 Home 64-bit
Monitor: Acer AL2223W
SSD: Samsung 840 EVO MZ-7TE250BW
(If you need any other system specs to give appropriate advice, please let me know)

Any suggestions that aren't "replace [component]" would be appreciated (mostly because that could quickly turn into "maybe it's the graphics card, replace that", $200 later it's not, "well then maybe it's the PSU, replace that", another $200, etc; to the point it would be cheaper to buy a new computer).
 
Is it possible for you to remove components and test without them. For example removing the graphics card using intergrated, removing a storage drive if you have one of those, ensuring that you have no cd's in your optical bay. I believe in general you have the general idea of what you need to do. Your goal is to pin point what was damaged or causing the issue. It all started with you turning off the power supply switch accidentally.

Is there a particular program you would recommend?
