Hi I wasn't really sure which category this would fall under, but it's likely a hardware issue I think.

I just put this new system together, and it runs great, but I'm worried about a slight quirk. After getting to the desktop, maybe 5 or 6 seconds later the PC seems like it's going to shut off. All the fans slow to almost a stop, and the lights in the PSU go so dim you can barely see them. Only for about a second, then it comes back to life. There isn't any issues on-screen or anything, I'm just wondering if this is hurting my computer, and wondering why it is happening. Thanks!

specs are in the dropdown, but here they are anyway.

Asus Sabertooth 990FX mobo
amd athlon fx 8150
gtx 560 ti
kingwin 750w modular
win 7 ultimate x64

I am not sure if it will help, but, maybe try updating your BIOS.

I cant really think how it can possibly damage your computer though..I would be more concerned if the fans would start spinning like crazy instead and your computer would roar like a beast which would mean heat problem or voltage issues =)

The 12V rail seems a tad low; but I believe within limits. I would leave HW on for awhile and see what happens. Also, I'm sure one of the Tech's will be along to help out. One other thing I would do is to check all connections to be sure everything is good and secure. I'm sure you have already done that; but you never know.

hey its worth checking, thanks for the advice. Like I said the thing works like a dream, probably the most stable PC I've ever had, but I'm just concerned the power fluctuation is hurting something.
