Hi guys!
I really need your help on this one. Usually I’m good at troubleshooting and finding solutions without having to start my own threads. This time however, it seems impossible to find a solution. Anyway, here’s the thing:
When downloading through utorrent, steam etc and listening to music/watching videos I get huge DPC latency spikes when touching the trackpad. The spikes result in robotic sound, computer hiccups and freezes (minor 1 sec freezes, every 3-5 seconds) But here’s the weird thing. I don’t get the spikes if I’m not touching the trackpad or IF I have a usb mouse connected to my laptop. For some reason, having a usb mouse connected solves the latency problem instantly. Then I can download, listen to audio and watch videos without any problems even though moving the mouse like crazy. So strange.
I have a Lenovo 710 14’ laptop with windows 10. Bought it a week ago. Kaby lake.
I7-7500u
Nvidia 940mx
8 gb ram
256 gb ssd
I have tried a bunch of potential solutions. Creating a bigger pagefile, updating all drivers to newest and also degrading to Lenovo’s website drivers (older). I’ve disabled bits and windows update. I’ve change the power scheme, so that the processor minimum is 100%. And a lot of other things. I can’t even think about everything I’ve tried.
I’ve used latency mon to investigate the latency spikes. Latency mon says that the culprit is WDF01000.sys. I’ve read that it’s difficult to say which driver uses that file etc. While using latency checker I tried disabling the realtek audio adapter. That made the spikes go away. I’m playing music through spotify, which can be quite bandwidth heavy.
It’s like my computer is really sensitive to heavy internet activity, combined with audio/video streaming. The task manager doesn’t show anything special when the spikes occur. The system interrupt process take up a bit more cpu and memory, but that’s basically it. Otherwise, the computer works fine. It’s just in the specific situation where I download, stream something and don’t have a mouse connected that this happens.
Any ideas would me MUCH appreciated!
