So, i was browsing some of my favorite news websites and out of nowhere my computer COMPLETELY powered off. Like i flipped the kill switch on the power supply. And it didn't even turn back on. Anyone know what could've possibly happened? Everything seems to be running fine now.

Sounds like a rapid power fluctuation so it may have shut itself off to prevent a problem?  Or as SPAS said^^^short circuit.

How old/long has the machine been running? New build? What is your PSU?

 

It's actually been of most off the day, i've been away doing things. The build is ruffly around a year old. I'm using a Corsair TX-650W PSU. Nothing was being pushed too hard so it couldn't have been not-enough-power problem.

I'm using a big and expensive surge protector. 

This means nothing. They are only rated for so many surges before they are shot and need replaced. Cost also does not correlate to quality. If it was sold by Monster and OEM'd by Belkin, odds are it's garbage (for example, because Belkin isn't known for quality, and Monster isn't known for cheap).

FX-8350 | GA-990FXA-UD3 | G.SKILL 2x8GB 1600MHz | 1TB WD RE4 | CM Hyper 212 EVO | MSI R9 290x Lightning | Corsair AX860i | Silverstone FT05B-W

Pentium G3258 | MSI Z97 PC Mate | G.SKILL 4x4GB 1066MHz | 500GB Samsung 2.5" | Stock cooler | Pending GPU | EVGA 500B | Antec DF-35

GoPro Hero 3 Silver | Netgear R7000 Nighthawk with DD-WRT | HP Officejet Pro 8610 | Canon iP110 | AudioTechnica ATR2500 USB

Downdraft cooler for mITX board (new build) | Desk mount mic stand | Pop filter | Anti-vibration mount for microphone | mITX case | 3rd monitor (matching existing 23.1" | Intel Core i7-4790K (for mITX build)

Actually, i just plugged my monitor into it just last night before i went to bed. Could the surge be the problem or the socket?

Check your temps just incase, if it shut down due to temps but it's unlikely since you were just doing light browsing and not gaming or anything intensive.

I monitor my temperatures constantly. Or, at least I do for my GPU. But my CPU fan is set to auto and i notice when it starts going faster. I doubt it was that.

psu issue for sure, what you had was a complete power loss.

Sounds like overcurrent protection. Your components needed too much power and the PSU shut itself off to protect itself.

^ this.

Okay, so what am I supposed to do? Hope my PSU just doesn't die entirely or get a new one?

 

Test the PSU at load with a stress test to see if it shuts off or the paperclip test first ideally to see if it's still good. It's a bit of an older unit but the TX isn't a bad one from Seasonic.

a good first step would be to put all of your components into a PC part picker list (including keyboards and such) and see how close the estimated load is to the max load tolerated by your psu.

I did that when i first built it. Lack of power and such isn't the problem.

I have literally the same PSU, it used to do this a lot before i cleaned all the dust out and cooled down my PC, the PSU would get super stupid hot and shutdown to prevent damage. Could be what's happening to you, i haven't had that issue since i cleaned it and opened my case and reduced the heat around it. 

 

or it just becoming faulty. happens with age.

I've been having my case door off for a while. How did you clean yours? I'm afraid if i clean it i won't get all the dust out.

I used an air compressor, but i would recommend canned air. Because air compressors can shoot little bits of water, so if you use an air compressor, let it sit a while to be sure its dry before you give it power again.
