[SOLVED] Computer shut down without any warning

PROBLEM FIXED!! It was overheating cpu this whole time!!

Hello all. Recently I've been having problems with my computer. It shuts down completely, as if the power cable was unplugged. There is no BSOD or anything, everything is just completely powered off. Whenever it happened I would be either gaming or doing something rather intensive. So I'm thinking it is something wrong with the PSU. However, today as I was just watching a single youtube video with nothing else running in the background (As far as I know), no other tabs open, just a browser with one tab, my display shut off. The monitor itself was still powered but nothing on the display. I look at my computer and the fans are all still running, I see green flashing from the MOBO where the ethernet cord is plugging in... everything else seems to be powered but the display is black. So now I'm thinking... is it the GPU? Maybe both??

What is your intake on this guys?

SPECS:

Antec EarthWatts 380D (Bronze certified)
Asus CuCore Radeon HD 5770
AMD Athlon II X3 Rana 445 @ 3.1ghz (4th core unlocked, otherwise stock)
BIOSTAR A880G+ AM3 AMD 880G HDMI Micro ATX AMD Motherboard
G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM

All stock cooling, using a rosewill challenger case with two 120mm fans (front and back) and one 140mm fan at top.

I think all my components are quality, no? It is my first computer built ~1 year ago maybe a little older. Everything brought new from newegg.

probably your power supply is not giving enough power, i doubt that your 380 watts is enough for your 5770. I remember my 4890 which was equivalant to a 5770 required atleast 450 to 500 watts.

I can think of two things: Overheating or PSU

1 year of capacitor aging with 380w PSU = ???

Your power supply should be able to handle that, and if I remember correctly, the earthwatts series is pretty good. Something could also be overheating; get a temperature monitoring program and check. Is this happening if you are under load? If it is, the problem is most likely heat or power. If it is just randomly restarting regardless of load, try reseating your RAM; my computer was randomly restarting a while ago, and I reseated the RAM, because I accidentally opened the lock, and the problem disappeared.

I'm basing the power consumption off of this BTW

I've research this psu extensively and the "internet consensus" on this PSU is that it can even support cards that draw more power than mine. Also, are you sure this video card requires as much power as a 4890? I just used hw compare and this vid card only used 108 to the 190 Watts the 4890 uses: http://www.hwcompare.com/1159/radeon-hd-4890-1gb-vs-radeon-hd-5770/

I believe it is load or heat. It doesn't seem to restart randomly, only when under stress. However, there is one instant which just happened today that prompted me to post this in which I was only watching a youtube video and my display turned black. Also, how do I get a temp reading once it has shut down? Is there a program that saves temps as it is running?

The PSU,if working fine should be up to the task,though yeah,this is either it malfunctioning,or the system overheating...

Good place to start would be to check the GPU and CPU temperatures under load,use something like HWMonitor...

Ok thanks. I'm thinking of using some sort of stress test software with hwmonitor open and just write down temps. Hopefully this is just a heat problem *crosses fingers*

Grab a temp monitoring program and check the CPU. If it's hitting it's thermal limit it will shut down to protect itself.

The 5770 is at most a 110 watt card.

On a PSU like the 380D? No change.
