I built a new computer about a year back i7 with a Corsair TX650W.

The PSU died after a few weeks, I got a replacement but it wasn't the same, it makes strange noises. I should probably have sent it back but didn't want to be without a computer for ages again, waiting on another RMA that cost me more in postage. I figured I'd put up with the noises.

This morning I could hear my computer whistling away (I wasn't using it), then I heard it reboot, first time win 7 had ever done that on me. I couldn't find any logs saying what happened other than it shut down unexpectedly. It seemed to run ok, the only thing I could see was the taskbar icons had gone back to default. I put last weeks backups in a file to keep until I'm sure everything is fine and took a fresh backup. I'm happily listening to some music and reading a forum post, nothing stressful and bang off it goes, like the power had gone out. It started up again, same as before.

Does this sound like the PSU ?

Anywhere I can look to find out why it crashed, been a long time since I had to deal with it and not in win7. In the reliability monitor is just says

The previous system shutdown at 16:43:47 on ‎15/‎02/‎2011 was unexpected.
 
I've been looking at youtube vids trying to find a similar noise without success. Its hard to describe but it kind of makes a click and the computer freezes for a second, then it chirps and whistles, almost like something starting up. It might do this once a hour or so, I've gotten so used to it, its hard to say.
