okay so i build my first system about 3 weeks ago, and everything was going great until yesterday when playing wow after about four hours, my computer shut down. no BSOD, nothing, when booted it promted that windows did not shut down properly, so i set windows to not automatically restart next time so it would show some form of error and continued on, until today after playing a games for a good 4-6 hours suddenly the screen went completely black, and the computer quickly turned off and back on, but was not responsive at all, so i had to hold the power button to turn it off. i ran windows memory diagnostic once on standard, it went through fine, i tried to run it again and it stayed on 21% for about thirty minutes. this could of been down to my impatience, or it could of frozen i dont know, but i did not complete the second tests. i have been monitoring the tempretures of both my CPU and GPU since day one and they have hit a max of 65C, with the average usually about 55C when gaming. looking at the event center, the shut down report is : - <Event xmlns="http://schemas.microsoft.com/win/2004/08/events/event">

Make sure all cables are securely fastened to their respective spots and after that this kind of problem is usually a power supply going bad

try stress CPU fist with prime95
then
try stress GPU 7870 with furmark for 5-10 minutes
if they both success

run both of them

i think the culprit is psu...
both furmark/prime will draw so much power and if it shutdown
PSU!!

yes, to test/stress the PSU, both CPU+GPU have to be 100%

Also, need to run Memtest on your RAM - could always be a bad stick. Other thought would just be to run with one stick at a time and see if that has an impact.

I had a similar problem with an older 8800GTX that was dying. Fine surfing the web but would crash the whole system under load. It's unlikely to be your GPU, but you never know.

I dont think its the GPU, as its been running games fine on all high for the first three weeks, it sounds like its either the PSU or RAM, im testing with memtest now, when thats done how could i test to see if its the PSU thats faulty?

How long did you run prime95 and furmark together? It should be for some time longer than you go before a crash, so maybe 8 hours?

Seen people recommend running memtest for 24 hours.

If the CPU, GPU, PSU, and RAM all pass the test then could be a MS patch that went wonky or even a WoW update. That might require a reload :( 

Also, do you have any USB (or other devices) plugged in besides the mouse/monitor/keyboard? I'd take those off to eliminate them as a problem.

If you're overclocking RAM or CPU, set that back to stock as well - could just do a BIOS reset.

Sorry for rambling, just thinking out loud.

thanks for all the suggestions, id take any advice atm lol. i only ran prime95 and furmark for like 5 minutes if that, i guess i should leave it on after memtest. no overclocking, and no usb devices plugged in apart from keyboard and mouse, and my VGA converter if that could cause it lol.
also just had a look at my computer and the test looks like this

Is this normal, it looks extremely odd.

I'm not familiar with memtest enough to know what it should/shouldn't look like - been a long time since I tried it.

Memtest experts chime in!

Run memtest pretty much if you have errors you'll know by all the red lines reporting errors lol.

Okay update, after a day later and using only one stick of ram and leaving out the stick i thought was "defective" the PSU decided to die, so i presume it was that all along. it tries to start up the computer and the blue light comes on, then it turns back off, then it tries again and turns back off, and continues to try. i presume this means the psus dead right?

that does sound like a PSU fail right guys?
