New Computer crashes while gaming

[squigglyz]

So when my computer arrived I thought it would be amazing to play games at max settings... however this isn't the story so far.

Specs;
Core; Intel core i5 3470
GPU; Radeon HD 7770
Ram; 8GB
Hard Drive; 2TB HDD
Motherboard: ASrock B75

Operating system; Windows 7 Home Premium 64Bit

Whenever I play a game I play the game on max settings with 80fps for a while with no dramas, however anywhere between 1 minute and 1 hour and the game crashes, I then get the helpless sign from windows "the application has stopped responding".

All games are legit from steam and stores, games include; Guild Wars 2, Metro2033, Minecraft, Planetside2 and darksiders-(i'm not going to install any more of my games in fear of wasting internet for the crashing).

I would get something like GPU-Z and HWmonitor to monitor GPU and CPU temps.

Also make sure your power supply has enough AMPs on the 12V rail.

the crashing could be related to overheating

what case are you using?

 

[squigglyz]

When idling GPU is 35 degrees Celcius
Cpu is 37 degrees Celcius.
When playing Guild Wars 2 GPU was at 62 Degreed Celcius
Cpu was at 54 Degrees Celcius.
This is going to sound ridiculous but I have no idea what the case is- The place that I bought it from are shut down for the next two weeks as they are doing renovations and no one is picking up.
Also how do I tell if my power supply has enough AMPs on the 12V rail?

If you take the side off the case, there should be a sticker on the side of the power supply unit. If you aren't sure how to read it, just snap a pic and post it.

Memory can also cause random crashes. I might leave memtest86+ running overnight and see if it picks up anything. Even 1 or 2 bad addresses can be enough.

before i start memtest here are the crash details of my latest guild wars 2 crash- if it helps could someone tell me and if it doesn't I'll run memtest.

I'd say it's memory.

 

[squigglyz]

If it is memory should i take both sticks out (2x4GB) and get new ones or just take one out or something else?

@Twelve25 -Here is the photo of my power supply

It's only got 218W at 17A on the 12V rail. I don't think that's enough. I would strongly suspect that is causing issues. It's one of those fake 500W PSU where the total adds up to 500W, but not where you actually need it.

As far as memory, just download an .iso for a bootable memtest86+ CD and leave it running overnight. But that is one of the worst power supply specs I have ever seen, so I would start there.

Just as a point of reference, my 530W power supply has 492W at 41A on the 12V rail. So you aren't even half what you would expect for a 500W unit.

Hey guys- so i took out 1 stick of ram (4GB's) and it's every games is working for hours on end- I haven't crashed once- thank you for all your help!

You're pushing it man.. the other stick of ram is probably not working because that cheap psu is powering all the other stuff and can't afford to give away any more voltage! if you get a malfunction dont say we didn't warn you

 

[twelve25]

I originally suspected RAM, so I am not surprised, but I wasn't joking when I said that is the worst power supply I had ever seen. It will cause problems sooner or later and for all we know power problems killed that stick of RAM.
