Startup time started to become an issue with this computer after 12 months, taking about 5 minutes to get to the Windows start screen.  A couple months later the computer would not start.  Diagnostics showed that the hard drive had failed.  After replacing the hard drive and running diagnostics showing it was working, I attempted to reinstall Windows and the computer would not even boot from the Windows installation DVD.  I assume this is a motherboard issue or something, but I'm no expert.  Seller offered no assistance since it was outside the 90-day warranty period.  I guess the low cost of purchase makes 15 months of life not totally awful, so 2 stars.
