Micron Millennia Desktop Stuck in Standby

I shut down the computer when we left town. Upon returning a few days later, I am unable to get it restarted by pushing the power button. It keeps entering standby mode according to the LED display, and is not starting up the hard drives or fan. How can I get it started again?

Have you checked the BIOS? I took my desk top on the road and got no response once I got to my location so I took all the caps off my BIOS stalks ( 3 prongs with a cap covering 2 of them on my MotherBoard) and put them back on and hit the power button and all was fine

I did as you suggested, but the result is the same. I tried it with the jumper off, and with it on, and with it on pins 2 and 3, with no success. In that mode, or with no jumper, the computer would not even enter standby mode.

I notice that with the jumper on pins 1 and 2, when I push the power button, the fan on the processor moves a little, and occasionally it moves a bit on the power supply as well.

So really, it's not stuck in standby--it's not working at all, right? Does anything at all show up on the monitor? Most likely the problem is a bad power supply and/or bad motherboard.

That could be I suppose. Nothing on the monitor. I replaced the power supply last year however, and the computer was working fine until I shut it down. The LED indicates standby mode, but the computer is not working otherwise..

You've apparently cleared the cmos which should have reset any previous shutdown info. You might try unplugging the power cord and leaving it for an hour or two. Most power supplies provide a small current to the motherboard even when off to provide, I think, for power-on options.

The standby LED being on may not mean 'standby' in this case. The power LED is often 2-color, usually green and yellow. You can get yellow if the PC is getting power but not booting up. I assume standby is also yellow.

I unplugged it overnight and just tried turning it on again, with the same result. I'm stymied!

Try disconnecting all the drives and remove all the cards except video. Then see if you at least get a posting screen. If so then one of the devices you disconnected must be the problem. If you still get no screen try another power supply if possible.

Oh, on your existing power supply, if it has the 115/230 input voltage switch make sure it's in the correct position. DON'T GUESS and don't switch it when the power supply is on or even plugged in.. It's 115 in the US. If no one messed with it then it's in the right position but I had that problem once.

That did it. I disconnected everything and it started. After reattaching things one by one, it turns out that a dvd writer was keeping it from starting up. But, I tried that drive again, and it started up with that attached also. I had to reconfigure the CMOS and BIOS so it would boot from the hard drive, but all is back to normal now. I suspect that the dvd writer may not last long!

Thanks for all you help.

I'm glad you got it working. Sometimes computer act as though they have a mind of their own.
