560 Disconnecting While Gaming

[jimjamjay]

Hello,
My computer's hard-drive stopped working a while ago, I recently replaced it and am having no problems as far as i can tell regarding that however this means I am using the system for the first time in several months.

The problem I believe lies with my graphics card, I seem to recall having this problem previously however I am not certain as it has been a while, and even before then used the system for around 3 years without issue it is a GTX 560, so quite an old card in a fairly old system.

I am finding that when I open games after a random amount of time, normally just a couple of minutes, the screen will go black and the monitor disconnect, and the PC will restart completely but without any video. I can then restart the computer again myself and it will turn on again properly.

I have tested CS:GO and Rocket League and have the issue after a few minutes, even on the menu. I have also tried some even less intensive games such as Runescape and have no issue.

I am led to believe it is a temperature issue but am not sure, could just be the GPU is finished, possibly PSU but again not sure.

I have tried using a different monitor with other connectors and have the same issue, at the same time I have tried plugging directly into the motherboard and have no issue however have not tried gaming under this.

MSI Afterburner shows 'GPU usage' to be up around 100% when I have the game tabbed in (normal when tabbed out even when game is running) whereas it rests around 20% not sure what this means.

Temperatures using MSI Afterburner:
Base: 30-40
Rocket League: 50-60

Full Specs:
Processor: Intel® Core™i5-2500k Quad Core (3.30GHz, 6MB Cache) + HD Graphics
Motherboard: ASUS® P8Z68-V LX: USB 3.0, SATA 6GBs, ATI®CrossFireX
Memory: 8GB KINGSTON HYPER-X GENESIS DUAL-DDR3 1600MHz, X.M.P (2 x 4GB KIT)
Graphics Card: 1GB NVIDIA GEFORCE GTX 560 - DVI,HDMI,VGA - 3D Vision Ready
Power Supply: 450W Quiet 80 PLUS Dual Rail PSU + 120mm Case Fan
Processor Cooling: TITAN FENRIR EVO EXTREME HEATPIPE CPU COOLER
OS: Windows 10

EDIT: I tried cranking the fans up to around 70% and was able to game for a fair bit longer but the crash still occurred

Thanks.

From the symptoms it seems pretty likely the GPU just cant handle what you are throwing at it anymore. Its most likely not a PSU issue as you would be having shut downs outside of games as well. With the age of the card it just may be dying after all the time of use.

Zethran, I recently had issues similar to the OP and the issue was with the power supply. The computer ran fine until I put it under load, like running the Heaven benchmark when the GPU would quit after a brief time. Another forum member mentioned the PSU, even though it worked fine with the previous card. Replacing the unit fixed the problem completely. The problem was evidently that the PSU could not supply the necessary power needed by the graphics card when it was running at max load.

I highly agree this could be the issue, but from what I understand he had been using computer before for a long time without any issue. Of course he hadnt been using it for months and the PSU could have messed up after not being used for so long. PSU's do lose wattage over time and he was already really close to its limit so odds are you are correct.

Monitor temps and TDP of the graphics card using GPU-Z. It will tell you under monitoring tab if there are any power or heat related issues.
