About a few months ago I was using Ubuntu (doing something in the command line) when it started lagging really bad. I would hit S (or any other key) and like 20 seconds later it would show up in my terminal.
Naturally I killed the machine and rebooted. The system started working just fine, but about 30 minutes later it did the same thing. Now I'm forced to use Ubuntu in 30 minute spurts. I've looked at my running processes and none of them are taking large amounts of CPU or RAM.
Luckily I've dual-booted so I could still use my machine. Now I need to get this fixed and I'm wondering what my options are. Will I be forced to do a fresh install or is there another way?
