Hi,

I just upgraded my 8 months old, stock, computer from acer (model no. mc605). I upgraded the graphics card to a gtx 660 ti, and the psu to a be quiet kraft 500 w. Everything seemed fine until I started playing games (i.e. Battlefield 4, Assassins creed 3 etc.) and after a couple of minutes of playtime, the screen goes black aand my computer starts restarting. I don't know what the problem could be, could it be the psu or the gpu? When I monitor my temp. there doesn't seem to be anything unusual.

My specs are as following:
Processor: intel core i5 3350p
Gpu: Asus dual cu 2 GTX 660 ti
Psu: be quiet kraft 500W
Motherboard: Acer mc605

Btw. since my case is not very big, it only has one place for system fan. So i Have a noctua 92 mm fan there...

Thanks in advance!

You might not have enough power. nVidia says you need a 450W PSU minimum. I always say go 100W over to make sure you're safe.

To rule out if it is your power supply not putting out enough power you can try limiting your FPS, which will intern stop the GPU working so hard.

I use it to limit my FPS when i play games on my mac when i'm booting windows so it doesn't get uber hot like macs do... (I do have a gaming PC i just use my mac for gaming when i go round my GF's or a friends etc etc.. Late 2013 so it has the 750m..)

Anyways... Once downloaded and opened. Open a game and just leave it in the menu.. Alt-Tab and go back to DXTory..

Once in DXTory navigate to the tab with...

If you're monitoring temps from your desktop, that's not the way to go. Games can skyrocket the temps. Try running the game in windowed mode and check your temps while it's running. Also, check if your PSU can support it, just to be safe, on a PSU calculator like here.

Thanks for the reply,

I have tried doing that and the temperature of the gpu always stays below 70 degrees.

Uhm, that's actually quite hot. I'm pretty sure that's what's causing the crashes. On some CPUs, if you go above like 65°C it'll throttle you, and then you're not getting enough processing speed to the game.

Anyways... Once downloaded and opened. Open a game and just leave it in the menu.. Alt-Tab and go back to DXTory..

Once in DXTory navigate to the tab with the microchip. 2nd from the end.

At the bottom i'll say limit FPS. Tick and set it to something like 30 or 20. It'll stop your GPU from working so hard, which will stop it from drawing so much power. See how this goes. If it's okay, unstick 'limit fps' and see if it crashes. If it crashes then your PSU isn't powerful enough. You could also lower your graphics settings and your resolution in game to stop it drawing even more power.

Also, once in DXtory make sure it has the game selected in the drop down list. It goes without saying that you should start DXTory before you start your game just so it finds it without any additional help.

I'd recommend doing this in Assassins Creed 3 as you won't have to wait 10 minutes to jump into a game like you have to do with BF4, and it's in a manigable enviroment.


That's just my 2p. Hope this helps.

70 degrees is absolutely fine while it's under load what you on about! The CPU will only start throttling when it starts to reach it's limit; Which is generally just below 100, if not 90. No where near 70. If the CPU gets even hotter when it's throttling itself, and reaches 100-110 it'll automatically turn your PC off to save itself from damage.

Even so if it was throttling at 70.. The GPU couldn't work as hard as it can't get the resources it needs from the CPU, which will causes the GPU's power usage to go down, intern it's temperature.

Thank you for the answer! I will definitely try this out.

Update your GPU drivers as well. http://www.nvidia.co.uk/Download/index.aspx?lang=en-uk

I'm pretty sure you will but you should see if your motherboard has a DVI/ HDMI or VGA connection, so you can plug your monitor in.

While the PC is off with the plug out, take out the graphics card, and plug the monitor into the motherboard. Boot and play a game. It'll probably run absolutely terrible, but it'll rule out a faulty graphics card. This will of course draw a lot less power, ruling out an underpowered system. 2 birds 1 stone!

I tried playing in windowed mode and it went fine, even with high ghraphics. But the issues seems to come when I'm playing in fullscreen mode.
