Heavy Stuttering - Games and Video

Hi there. This might be long winded, but I'd really appreciate some help. I'm really frustrated with this computer, and I've been researching for hours and hours and tried everything I can fathom with 0 results.

Anyway, before I start, this is my system:

HP Pavillion a 6552f upgraded to:
550ti EVGA
CX600 Corsair PSU
250GB Toshiba hard drive, 2.5", 5400RPM
1x4GB RAM
Core 2 Quad q6600 OEM 2.4ghz

Anyway, this is an ageing computer, but I can't really afford to buy a new one in one sitting. I could save for one, but chances are my computer would become unusable way before I could afford a new one.

I just replaced the old PSU from the HP with the Corsair, and replaced an old upgrade from a 430GT to the 550ti. At first, I didn't notice anything, but when I downloaded and played Path of Exile, the game stutters severely, even on low or very high settings. The video card can easily handle it on max, because it runs at 60FPS normally, but it will stutter every second or so.

When I watch Youtube videos or anything for that matter, the playback is never perfectly smooth. It can stutter (although it's less severe and watchable) quite often and is irritating because I know it's there.

Anyway, I've done some testing, and I don't think it's the hard drive. I'll link the SMART test at the bottom of this page. I've also run World of Warcraft on Ultra, and I get 60 FPS, but the game will stutter slightly (not massively, but it's noticeable).

My CPU is OEM, so I have almost no control over it. I hate it so much, but it's either new MoBo and CPU and I can't play Diablo 3, or I play Diablo 3 and upgrade later.

I've noticed some kinds of stuttering without the new PSU and GPU, so I'm confident it's neither. I honestly think it's one of the ageing parts on this computer which would be:
-Motherboard
-RAM
-Hard Drive
-Processor

I've upgraded my video driver, my Realtek sound driver, and I've just run out of options.

I'm almost certain it's either a setting, or it's a hardware malfunction.

If you have any idea about what this could be, and what I can do to fix this, please let me know.

If you have any way of diagnosing that it's a hardware issue, I'd also like to rule that out as well.

Thanks so much, I appreciate your help.
