Guild Wars 2

Alright so I recently got a Vapor-x 7770 factory OC’d gpu, and anywhere from 30 minutes to 3 hours I get a crash that looks like this: http://imageshack.us/photo/my-images/94/dsc00537yc.jpg/

That’s not my pic but what I’m experiencing happens just like that, except the color changes to whatever was most prominent on the screen at the time. When it happens I can still hear my skype call/sounds, but I have to hard restart my pc to get my screen back. It’s only happened in GW2 and none of my other games. (I play BF4, Saints Row 4, Skyrim, etc) Never had the problem in any of those.

I’m currently using the 13.12 drivers for my gpu, and my specs are as follows:

500W PSU
Vapor-x 7770
I7-2600 3.4 ghz
8 GB of ram 1333 mhz
1.5 TB HDD

Never had this problem with my old gpu, I just don’t know what could be causing it, maybe the card is failing? Anyways input would be appreciated, thanks guys.

Edit: forgot to add temps too, GPU sits at ~50c and the CPU sits at ~60-62c when there’s a ton of stuff going on, and 57cish when I’m just out in the world doing things. (Stock cooler ftl.) I know those temps are more than fine so I know this isn’t a heat issue.

Could be the PSU. A NON OC’d 7770 uses 80w of power, depending on how OC and if the core voltage on the GPU was raised for the OC, it could be pulling 120w+ power now.

And your 500w PSU is never going to push 500w of power. At best you can hope for is about 435w and that’s with a top of the line PSU, and if its new.

Right that’s what I was figuring too, so I ordered a 650W PSU a few days ago, need to replace the 500W anyway, like you said it’s never gonna push 500 and it’s a little low by today’s standards. I just don’t have any idea why it’s not happening in any other game, really strange. Maybe it’s related to the amount of GPU usage and what not, though I sat on BF4 for a good 6 hours last night, really strange. Appreciate the input none the less though!

This game, GW2, is very strange when it comes to ‘how’ it uses your system.

The OC on that GPU could be pushing the PSU JUST enough to pop your system when GW2 puts your CPU/RAM under load. All it could take is an extra 14w that your PSU cannot supply.

650w is the bare min I would go today. With all the K series CPUs and OC based GPUs out there, 750-800w is where I would be looking (ESP true if you are considering Water Cooling and pushing the Voltage of your Ram higher then 1.65).

I have to disagree with this:

“And your 500w PSU is never going to push 500w of power. At best you can hope for is about 435w and that’s with a top of the line PSU, and if its new.”

Good quality power supplies DO put out their rated power while staying within ATX specifications:
