Thank you for the help. If this cord doesn't fix it (I'm not banking on it but..y'know. Hoping) then I'll look into getting a new power supply. Those aren't hard to install are they? =[
It's relatively simple to remove and re-install a power supply. After turning off the computer and switching the power supply switch off, there are four screws holding the power supply to the case. After unscrewing them it's just a matter of unplugging each power cable (motherboard, ATX12V, hard drive, DVD drive) after which you can slide the power supply forward and pull it out of the case.
Judging by the cable management in the pics you might find it easier to leave that extension cable for the ATX12V plug that feeds its way between the graphics card and the motherboard just so you don't have to worry about removing the graphics card to pull the cable out and run the new cable.
I'm not sure what options your motherboard's BIOS has, but a way to see if the power supply is the culprit without spending any money would be to undervolt your processor. It seems like your problem is intermittent which would mean the power supply is right on the cusp of being able to supply enough power, so reducing the processor voltage would reduce the overall power consumption of the system and should increase stability.
Looking at this Tom's Hardware article
on undervolting the Phenom II X4 955 and using it as a template, you should be able to manually set a voltage of around 1.2v and remain stable while reducing the processor's power consumption by about 12%. If it remains stable then it's very likely the power supply is the issue and you'd want to get a new power supply (and you should still be able to use the current power supply at the lesser voltage until the new power supply arrives).
