Although that's somewhat surprising that seems to make sense. I am up to date on every Windows updates though unless there's something I'm missing.
Could be as I have ELAN hardware but I'm using a wireless mouse and Lenovo replaced my mousepad when I had trouble with my hard drive. Additionally, whenever this problem of mine happens, it's more like my PC stalls or freezes for half a second and both the audio and mouse glitch out, it's never one or the other as far as I can tell.
I do think I'll try to upgrade to W10, as I think it did clear up that problem the last time I tried it. Unfortunately, I think I got a BSoD or blue screen and had to reset my PC to default settings but that may have been because of my hard drive. Since then I think I tried W10 again but the update froze and I had to force shutdown my computer after 4 or so hours of it frozen on (I think) 70%. In any case, I'm a bit weary of trying to update again. Though that could've been because I tried to go from W8 -> W8.1 ->W10 right after the other?
I don't think it is according to Speccy and Lenovo repairing it not that long ago but if it is still a problem what would be my next steps? And if W10 somehow fails?
Also, thanks for your help Nathan
