I'm running my RAM 1:1 with FSB. I don't have my settings in front of me because my computer is currently powered off, but my CPU is clocked at ~2.645 GHz, which is about 294*9, so the FSB is about 1176 and the RAM is about 588. There's some definite rounding going on here, so things aren't exact. As I understand it, that setting is a little more than half of what my RAM can supposedly run; it's way underclocked. I'm under the impression that running above 1:1 gives you no performance gain.

I don't have a UPS, though I am very interested in getting one. I've not read too much about them yet, but from what I've seen, the ones that are really worth getting are very expensive, which is why I don't have one yet. Are there any good inexpensive ones?

I've been running my PC again today to see what it would do. Everything was running fine for the longest time. I did a lot of copying files from an SD thumbdrive, played music, etc etc. Eventually I started running Crysis, but I hadn't gone beyond the menu (so nothing had been loaded yet) and had it minimized on the desktop. I stepped away from my computer for a minute and the thing shut off again. This time I was able to catch the glimpse of the back of the computer, and the power supply light was dead (indicating no power). After a few moments, there was an audible click and the light came back on.

Now, I'm assuming this indicates the power supply is faulty (if there are any other possibilities, I'd love to hear them. Perhaps some other component is acting up and this is some sort of power supply failsafe?). Could I have done something that damaged the PSU to become faulty? Additionally, I find it interesting that every time this has happened while my computer is on, it's been while Crysis has been running in some way, although it did act up after I shut it down last night.

If you guys think this is as clear an indicator as I think it is, I'll go ahead and RMA the thing. Thanks for all the help so far.
