$300-400
okay, going to check both pre builts and builds to see what would be the best computer, going to take a bit of time.
(for the people who are paranoid of pre builts, they can offer pretty great deals at $300-400, some of them even better deals then building a computer.)
No, it didn't. And nothing was installed recently that I was aware of.
Would reinstalling the OS fix it?
yes, it's a software error.
you can back up your files via linux live cd if you want.
