Mouse cursor freezing, typing too

I'm don't think this should be in hardware, because my keyboard (K350) and mouse (M570) do work. Batteries are "good" according to SetPoint.

I performed a fresh install back in the first week of March when I picked up my SSD. What has begun happening in the last couple weeks is that when I have IE9 open and I am either running a video or have more than one tab open the mouse cursor will freeze up, or the keyboard will hang, and "drop" some letters or show the ones I typed after a delay. I have scanned with AVG and MalwareBytes. Both come up empty. I have also adjusted the USB settings to disable the USB suspend option, to no avail. I have the latest drivers, and software from Logitech. Everything is wireless, unifying, and it doesn't matter how far away you are.

This is really getting on my [expletive deleted] nerves. Has anyone encoutered anything like this? I could only find one vague reference to a Windows update not installing properly.

I have a solid board (Asus Sabertooth), with plenty of memory (16GB DDR3-1866), CPU not even a year old, AND an SSD (Vertex 3 120GB). It just did it again when I typed "GB". Took a full second to appear, and I only have ONE tab open. This should not be happening, and didn't until recently. :mad

Anyone have any ideas?

 

Just a follow up, I was ready to flip last night as the freezing got to be a MAJOR pain in the a$$.

I run the Aero effects, and happened to glance up in the corner of the desktop as I closed the browser, and saw the Windows Media center sidebar gadget rolling from promo, to promo. Thought to myself, "do I really need it, when I can use a shortcut?".

Voila!!!

So far, so good issue seems to be solved. Whacked, right?
