My computer has recently occasionally been just having the monitor go black, software immeadately crash, and all the fans switch to max speed. The problem started about one month ago, occurring once per week usually when not playing a game. It however had a false start on powerup before windows even started, and i've had a reload of windows since then by chance, so I am convinced software is unrelated. The problem happened twice today, so now i'm alarmed. It seems to usually happen when i'm not playing a game, but rather doing mundane internet activities like writing angry things at people with text.

I suspected possible overheating, but everything is clean and tidy, my aftermarket cooling heatsink and fan hasn't budged and is seated snug, but just now I found that in the bios the only hint I have now of something wrong is that one of my voltages has dropped below specification.

What should I make of this? GPU or PSU issue perhaps? Maybe my board is asking for me to throw it into the blender? I built this guy in 2011 and he's basically that board as listed in the image with an AMD Phenom II X4 955 Processor 3.2 Ghz, 8 gigs of memory windows 7 home premium with an ATI Radeon HD5880, sitting in a HAF932 case (but no worries, ive eliminated the HAF932's known electrical causing issue by yanking the front panel - it's not that).

Money is no object but I'd rather fix it then scrap everything and build something new given its.. not too old age

@trampus123: 3.3V is not made by the motherboard VRM's. The VRM's provide power to the CPU and RAM and feed off the 12V lines. The 3.3V power is provided by the PSU.
