Hi there,

About 3 years ago I decided to build a new system for video editing and also some gaming. the specs are as follow:

-Case: Antec One ATX
-Mobo: Gigabyte Z77X-UD5H z77
-CPU: Intel i5 3570k 3.4ghz running "everyday OC" of 4.2ghz with a Cooler Master Hyper 212 Evo cooler
-GPU: PNY GTX 670 2gb (reference design, replaced cooler with an Arctic Acelero and ramsinks)
-Ram: 4x4gb Corsair Vengence Blue DDR1600 (running at 1600mhz)
-SSD: 1x OCZ Vertex 4 256gb (windows) 1x SanDisk 240gb (osx)
-HDD: 2x Seagate 2TB in Raid-1 (windows storage) 2x Western Digital Green 1tb (osx storage)
-Asus Bluray Drive
-PSU: OCZ ModXStream Pro 700w

Overall it's been a great system, edits my old FCP7 projects great while in OSX (since migrated back to Premiere so the OSX install is less useful).

My only problem is it occasionally crashes - hard. like black screen, audio cuts out, have to hard powerdown. This usually happens when playing very intensive games, but not when rendering or running benchmarks (and thus hard to replicate). It's a problem which has plagued me for the last two years or so. It didn't run into it very much until I played Tomb Raider - and at first I just thought that game was buggy (as it was at launch), but then I had the same problem in Arkham Origins, and now I've even been getting it occasionally in Dragon Age 2..

looking back, it looks like I picked a crappy PSU - it was on sale and I hadn't had much problems with OCZ in the past (despite some reports I'd read). But I also cheaped out on the GPU (was on for amazing deal at the time).

So, my real question is - any suggestions for how I can test if it's the PSU or the GPU? I've ran ramtests and all that already... and there is lots of cooling for the GPU and CPU..
Or, recommendations for PSU to power this system?

Thanks for reading!

last time I had that happen was due to bad PSU, replaced it and we were golden
 
Well remove that GTX 670 card from the system and use the onboard video only. That'll let you know whether or not the system is stable as is.
 
thanks for replies!

hmm I'll try taking the card out and see how stable things are.. only crashes while gaming though.

if I were to replace the PSU are there any recommendations? is 700w overkill? should I just get a platinum rated lower wattage?
 
This is a solid cheap replacement:
$52 - XFX TS Series 550W PSU

went a little crazy and ordered a new/better PSU but also found a used gtx 670 for cheap on craigslist.. so if its just my PSU crapping out I will hopefully be enjoying some 2 generation old SLI tech and pushing the old games I usually play a bit harder :) will update
 
so i swapped the psu and so far so good! added the second 670 and enabled sli and still good, so problem solved
