Computer boots but no power to monitor, mouse and keyboard

by mortix / January 9, 2013 4:41 PM PST

As of exactly a week ago, I bought a brand new HDD and reinstalled everything from zero. I used the back-up disks to go back to factory settings. This morning my mother turned on the computer and what she said is that the computer started normally up to the log in screen, only that there were no users, but a message saying that there is something that needs to be installed, and that the PC will restart automatically. When I woke up, the PC was turned off. When I tried to turn it on, the lights would go on as usual. All fans work properly, only that the monitor says "No signal", and the mouse and keyboard have no power. I tried taking out the RAM, and yes, there is the beep from the motherboard. I tried changing the monitor, same result.
I have an HP Pavilion Elite HPE-410f, if that helps.

I'd try another motherboard. The problem seems unrelated to the new HD.

I really wish there is another solution, since I know that buying a pc component requires some thorough search to see if it does not have conflicts with other components.

In the meantime, before the PC wouldnt boot, I connected a bad HDD from a friend to see if we could save his files, but the PC could not boot, after I connected his (together with my HDD with the operational system). and i didnt try booting up the pc since, so this is like a prelude to what happened to my mother.

It's safest to connect another hard disk via USB (using an enclosure or a adaptor cable). It seems that now you messed up something inside the case (it's likely to be related, indeed). Open it again and check all connections.

I opened it again, and to my knowledge, nothing looks wrong, everything is plugged where it should be.

But still something is wrong, hardware-wise.

Ok?

From what your saying, you booted the board without ram and it gave the proper beep code.
The fans were running normally, and led's were right so power was going through the board.

I'm wondering if that "something that needs installed" might have nothing to do with the problem. That something stopped loading when the ram went south.
I would , if possible, find enough known good ram that will work with the machines OS , and see if it boots.
If you have multiple sticks , I would test them one at a time. Remember to ground yourself when working within the machine. Don't want you toasting the motherboard, over a possible ram issue.
