My computer occasionally glitches anywhere from multiple times a second to once every ten seconds. By 'glitch' I mean any audio playing goes kzzt for a fraction of a second, and the mouse cursor skips, everything just skips. This happens for music stored on my hard drive and streaming video/audio.
This only started when I reset one of the routers at my house a few days ago. There are two routers, one plugged into the other, both have wifi, but the second (the router that is plugged into the other, not directly to our ISP or whatever) was more reliable and the one I used. Before I remembered this, I tried a few fixes:
I tried using the Windows Repair tool from Tweaking - didn't work, so I restored my old registers.
I reinstalled my audio, wireless card and video drivers to the newest versions - didn't work.
I became religious and tried prayer - didn't work.
finally I remembered when this actually started and I unplugged one of the damn routers (the good one). The problem went away, no more hitching, but only for ~5 minutes and then it returned.
At this point I tried setting my PC to airplane mode, and suddenly there were no more hitches at all. Both for audio on my PC and for videos that I gave time to buffer with an active connection, and then set airplane mode. Turning wifi back on and watching those same buffered sections does produce the hitches.
Right now my wifi is on and there are occasional hitches, but not as many as before I began to type this out.
(This does not happen to my laptop, which uses the same wifi)
I don't understand what's going on.
(I remember reading something about having multiple audio drivers could do this? And I do have two 'sound' tabs on my DirectX diag tool thing.)
