Just built a system a few weeks ago which has been running great. However, this week I noticed some odd behavior. When I power on the computer, the fans spin, lights turn on, nothing on the screen, and it shuts off. Then 2 seconds later it starts up. My screen stays black (besides the asus logo, and press DEL to enter setup message) until suddenly I'm at my desktop. no windows loading screen or other bios messages.
I havent noticed the computer running any slower than usual, or any other side effects. Also, when I restart the computer sometimes it decides to shut down, then power back on.
