| 1450722 | 2018-06-18 09:55:00 | Number 1 son's gaming desktop has borked. After booting up and prior to login screen, a variety of psychedelic patterns including sparkly little green dots, followed by a lovely mosaic pattern of grey and white squares etc etc. Sometimes it boots up okay. Downloaded GPU-Z - ran the render test that maxed out GPU - no issues or discernible spikes in temp - went upto 64c and fans increased appropriately to around 60% of speed. He then played a game - screen went wonky and BSOD. Downloaded Unigame Heaven to sress test the GPU and machine rebooted 3/4 of way through the test. Also ran memory check and that came back fine. It starts in Safe Mode without any of the weird screen artifacts making me think it may be driver related but not sure. It appears every BSOD episode has 4 processes / calls highlighted in orangy/red - nvlddmkm.sys, notskrnl.exe, dxgmms1.sys and dxgkrnl.sys. At the top of the BSOD reader screen each episode is caused by dxgkrnl.sys. PC is about 5 years old. Powersupply is a Seasonic Bronze 620W and GPU Card is about 3.5 years old and is a GeForce GTX760. Been running perfectly until this. Last update was GPU drivers around 2 weeks ago. No issues since then / until now. So, as a betting man, is this Card, Powersupply, Driver or something else entirely :) I have a spare / old 560 I can swap in tomorrow as a starter. Thanks for your help |

The graphics card is stuffed . Yes it can run quite happily in 2D mode . Gaming is the test . 3DMark is an excellent hardware tester for GPUs . It stresses them and tests thoroughly . |

| 1450725 | 2018-06-18 23:26:00 | It does sound like a graphics issue and the temperatures sound ok so I'd probably have to agree with piroska. Swap the 560 in and give it hell, should confirm the issue well enough. |
