I built a computer for my aunt quite a while ago...and now she recently called me and told me that it smells pretty bad, and she said that she couldn't quite describe the odor, but it didn't smell like it was burning at all. At first I thought something was burning, but she said that it doesn't smell like a burn and she's been using the computer fine for about a week when it started happening. I'm going there tomorrow and I told her to keep it of for the meantime, but what could it be? If it's not a burn, could it be a plastic melting? She's using the computer fine (and it's on almost 24/7), so it might not be on the major components, but what could it be? Thanks for the help members! Also, she just told me that the computer won't turn on anymore. Could it be the power supply?
