It's doing it again. There seems to be something wrong with windows, all of my UI is laggy, scrolling is jerky and unresponsive, video and audio playback are choppy, but for no perceptible reason my download speed is back up to 11-12 MBs. I have no idea what is going on here, every kind of diagnostics I can find say there isn't anything wrong but the problems persist.
I've tried just about everything short of re-installing windows (which I absolutely do not want to do, but if that is what it comes down to I will), can someone help me out here?
It occasionally clears up after multiple restarts, which makes me think that something is failing to initialize somewhere.
This is completely insane, the problem is now constant, nothing I do has any impact at all, every single diagnostic shows no problems and reports that my system health is good. Every device shows green, even booting from the install disc did nothing.
I looked into slowdown causes and the only thing that is even remotely recent has to do with a recent set of security patches, but I didn't install any of those until after the slowdown started, so they can't be the cause (tho' they could very easily be compounding the issue).
It effects everything with an animation, there's a three second delay when I scroll, when playing Skyrim my mouse control is completely smooth and normal but every single animation plays out in slow-motion. I've checked every setting and none of them are wrong, but this inexplicable lag keeps happening.
Opened the case, cleaned then re-seated everything, on startup the system was much faster but very noticeable lag issues persist, especially when opening a window or refreshing the contents of an open window.
Download speed once again inexplicably throttled to 1.5 MBs.
