Ah, sounds like we have slightly different issues then. Thanks very much for checking, though. I really appreciate it :).

It's just odd because I believe when I bought the laptop, the GPU flatlined at 0% unless it was being explicitly used. Since you have a Lenovo, you probably don't have any Dell software installed, implying that mail929's response might not tell the whole story. The only thing I can think of might be that I have f.lux installed, which dynamically changes the hue of my screen depending on the time of day. It could potentially be considered a "full-screen" program that's always running and constantly making changes depending on the time of day. Do you use f.lux as well?

Same laptop or different?

Thanks for your response! Ideally I don't want to disable the GTX 1050 entirely, just when it's not being used for games. Any chance you could check with your friend which program it was that caused the issue? Would be a huge help. FWIW, it seems like the GPU still cycles between 0% and 1% when I have the integrated graphics selected in global settings.

Hi Everyone, I recently bought a Dell XPS 15 9560 with a beautiful 4K screen, intel 630 graphics and a GTX 1050 GPU. It's generally working well, though I noticed in MSI Afterburner yesterday that the GTX 1050 seems to be turning on an off at roughly 1 second intervals even when its not being used by any programs according to the NVidia Control Panel. With NVidia Inspector I was able to see that it's only cycling between 0% and 1% load repeatedly, but it just strikes me as odd that it would do so even when I'm only looking at the desktop, where the Intel HD 630 should be doing all the work and the GTX 1050 should be entirely disabled. Is this normal? Does anyone have any ideas as to how I can disable the GPU completely when it's not being used by a program that really needs it? I am not particularly concerned about degrading my hardware since it's only being used a very small amount, but it seems like it might adversely affect my battery life, which is sort of annoying. Any advice or ideas you have would be greatly appreciated .

Thanks very much for posting such a helpful response. I must admit that I did not try a CMOS reset, but I have requested a refund from Amazon and am going to buy a new board soon. I would try a CMOS reset, but I've already packed everything up and it's scheduled to be picked up in the next hour. That said, when I looked at the CPU socket really closely while packing it in, I could see a few of the pins in the socket were bent...I think this is the likely culprit. Wrote to ASUS tech support and they recommended returning the board. [UPDATE] So, I RMA'd the motherboard and everything is working just fine now. I think the bent CPU socket pins were likely at fault. If anyone comes to this thread with a similar issue in the future I would recommend having a close look at your CPU socket on the mobo itself. Bent pins make for a bad time!

Hi Everyone, Just built a brand new gaming PC with the following specs: Asus Z170I Pro Gaming Mini ITX Motherboard HyperX Fury 16GB (2x8 GB) 2133 MHz DDR4 memory i5 6600K at stock speeds with CoolerMaster Seidon V2 water cooler Samsung EVO 850 500 GB SSD Corsair CX450M 450W PSU Fractal Design Define Nano S case Will eventually buy a GTX1070 I'm having some really odd issues with RAM installation. Basically, the mobo has two slots for DDR4 memory and supports up to 32 GB total memory. When I slot both of my HyperX Fury sticks into the mobo and power on, the screen stays black (doesn't make it to post), and the DRAM and CPU error lights on the mobo alternate in shining every 30 seconds or so. Interestingly, when I remove memory from Slot B (so only Slot A is filled), the machine is able to post just fine and easily detects the installed memory stick correctly. When I slot the same functional memory stick into Slot B (leaving Slot A empty this time) it is unable to post and the DRAM/CPU lights flash again. I have tried this will both my memory sticks and they are both functional, so I doubt the RAM itself is at fault. A good Samaritan on Tom's Hardware suggested that my CPU memory controller may be at fault, so I recently reseated the CPU/cooler and blew out the CPU and memory slots in case dust was to blame. I have also updated my BIOS to the most recent revision and tried enabling an XMP profile with while 1 stick is installed to see if this will allow me to use 2 when I reboot. Unfortunately my situation remains unchanged and I am not sure what is at fault. My guess is it's either the mobo itself that is faulty, or the CPU memory controller is misbehaving as was suggested to me, but I'm not sure how to determine definitively what is wrong. For what it's worth, other than this odd RAM Slot B issue, the computer is fine and I have been able to install Windows 10 64 bit successfully using just one stick. It may also be worth mentioning that I got the mobo on Amazon Warehouse Deals to save a little cash...the product is supposed to be new with just a slight scuff to external packaging, but when I got it the internal packaging and user manual had been pretty roughed up and there was no CPU slot protector included on the mobo itself. One of the pins on the USB 3.0 connector was bent and I had to set it straight manually. None of this is definitively damning, but it's making me lean towards requesting a replacement from Amazon. I just don't want to do so until I have exhausted all troubleshooting options under my control. Any help you guys can offer would be really appreciated in figuring out whats going on!
