Damn, looks like my 360 died upon downloading the auto-update for Oblivion. Hopefully I can get it repaired for free since the system was purchased before 2006. I'm calling Xbox support later tonight...

[UPDATE] Well, it turns out that I'm past the one-year warranty date. To get my console fixed, I have to pay $140. The good news is that I get an extra year of warranty after I get the system back, get a month of Live Gold, and don't have to send in my hard drive and worry about losing my data. But still, $140 for a faulty system I paid $400 for seems a bit steep. Maybe I'll try fixing it myself...

[UPDATE 2] So, I called back a couple days later and the person I talked to told me I was still under warranty. A bunch of information exchanged and a week later, and I receive my repair box in the mail. So I open it up and take out the instructions: put the console in the static bag, attach the styrofoam ends, put the return sticker on the outside... wait, there's no return mailing sticker! Damnit. So I call up support for the 3rd time, get an apology and the rep says that a whole new repair package will be sent to me.

One week later and I haven't received a box or e-mail notification of a box being sent, so I call up support for the 4th time. After explaining the problem, and being put on hold for 15 minutes, I found out that the last rep I talked to did not correctly send me a new repair box. Argh! So now they are sending me a new box again. At least this time I got a verification e-mail, and hopefully there will be a return shipping label with the new package.
