Me again. About a month ago I repaved the family PC. If there were a decent iTunes clone for Ubuntu, I would have gone with it, but we're stuck with this, and I'd prefer not to go the hackintosh route.
All was fine. Viruses gone, startup much faster. But about a month ago, we find that every few days the machine shuts down instantly without any warning. Startup sometimes comes up in chkdsk mode.
Are there utilities out there I can test the disk and RAM with, to find a bad sector or a bad chip or whatever? Anyone have other suggestions?
Let me know if hardware specs would help. The machine just shutdown, so I'm using my more reliable MacBook; it's too late to restart the machine right now.
