I bought my computer about 4 months ago and it had worked fine. Starting yesterday, it shut off randomly. I could turn it on, and it would work for a bit, then it would turn off. It has been doing this ever since. I have got in an hour of Planetside 2 and it didn't turn off, but a couple hours later it shut off while I was browsing the web. I've tried cleaning all the fans and trying a different wall plug, but it still keeps doing it at random. It doesn't beep or anything, it just shuts off. It also doesn't try to turn on while it's off, it stays off.

My guess is that it's the power coming to my house. It gets weird when it rains, and it was raining yesterday. Could inconsistent electricity be the problem?
