While using my web browser(firefox) the entire OS locked up for about 10 seconds(except for the mouse, I could still move it, but it wouldn't highlight or allow me to click anything). I also have a USB device that streams data with the OS and it lost connection during this time, even though my mouse which is USB did not.
I started getting artifacting, if I close/ minimize one window it would leave parts of it on another.(Seemed like a bad GPU/GPU Driver). The next trick was when I got to the desktop, the wallpaper had become a garlbled mess of what the last web page I was on. The taskbar was drawing perfect though, desktop icons where questionable, can't remember for sure, but I beleive most where visable. I kept getting intermitent OS lock ups(over about 5 minutes), Tried using Chrome, couldn't type in a full search query. Ran firefox again, and Downloaded the latest MS Malicious removal tool. Tried running it, it kept hanging up(gave it only a few miniutes). Finally decided to shutdown and disconnect a few storage HDDs, IDE and SATA(easiest suspects to eliminate). System rebooted fine, download Crystal disk, checked SMART date, all good. Checked PSU voltages, all good. CPU and GPU Temps, all good.
System seems to be running fine now. Ran a quick scan with MS MRT, came up clean(Running a full test now, should come up clean as I'm quite strict). I use Avira for AntiVirus and have Java, Flash, Browsers, etc up to date, as they always are.
So my question is, what caused this lagging/locking up/artifacting. It seemed like it was something more major than a storage HDD that was just sitting idle having a issue, but that is the only thing I changed, the system wasn't under any particulare heavy load before or during the issue. I've never seen a wonky HDD with these symptoms before.
