Frequent Bizarre Lockups/Freezes, but Still Running
Hello forum users,
I am running Ubuntu 12.04 on a custom AMD machine. My OS boots properly and works fine for a while, but then will freeze seemingly at random. The first couple of times it happened I thought it was just a normal lockup and just performed hard restarts, but then I noticed the computer was acting strangely while it was frozen. The mouse and keyboard both fail to work during these freezes, but yet the computer is clearly still working. I decided as an experiment to open up my system monitor and then wait for the lockup. Sure enough, after the mouse and keyboard froze, the system monitor continued to log processor function and network function as well, just at a reduced framerate. I decided to just let it do its thing for a while. The screen soon fell asleep, and occasionally it would awaken just to show my blank wallpaper, still not responding to mouse movement or keystrokes.
I don't know for sure yet, but this could be an issue related to high network volume. I had to use ndiswrapper to get my Netgear WNA3100 working, and it works fine (other than this freeze glitch which may or may not even be related). However, it could be a network volume issue because it froze a few times when I was attempting to install massive system updates at first (this is a new system) and its freezing now, perhaps due to my near full dropbox automatically downloading all of my files.
My computer is a custom build. It is running Ubuntu 12.04 x64.
Gigabyte mobo, AMD FX-4100 CPU, 8 gb matched RAM DDR3, a 64 gb SSD, and for graphics a NVIDIA GTS450. As I already mentioned my wireless card is a Netgear WNA3100 usb.
There are no hardware problems, its a relatively new system and my Win7 install works fine.
