I'd Appreciate any help in this situation.

I was Stripping my PC Last night to rebuild into a custom Case (Details Classified Patent/Completion Pending, I'll post a pic if I can get this Error Fixed)
While doing a Naked assembly (case-less on desk) I noticed my Laser Mouse didn't connect so I tried plugging in my Monitor and there was a no signal message. After much Fiddling to no avail I decided to post in a forum, any speculation is welcome as I'm a new again pc re-builder (last custom 2001)
as far as I can tell everything seems to be plugging in correctly Memory in the correct port, I can hear the start up and HDD Whirl and there are no obvious noises or lights just not monitor output and my Laser mouse and USB Key board flash upon plug in then loose power and do not transmit. Like I said, any Speculation would be greatly appreciated.

Hi Saetha, and welcome to BleepingComputer.

I'm a little confused as to what is going on here, I understand that you are putting the components together outside of the case, but am not sure exactly what you are describing as the problem.

Is the mouse and keyboard PS/2 or USB types?

Are they wireless?

Are you plugging these in while the PSU is turned on?

The Mouse and Keyboard are USB wired, and the problem is that the Monitor keyboard and mouse are not getting any attention from the PC. No connectivity while the PC sounds to be booting correctly. Thanks for such a quick response.

Is the fan on the PCU spinning up?

Have you checked in the BIOS so see that the mouse and keyboard are enable as USB devices?

Is the motherboard isolated so that it can't short out?

Go back over all of your connections, if this was working before you took it out of the original case then the chances are that this is a connection problem.

If there is no monitor output...how can you determine what is working, beyond the fans and PS?

You get the "no signal" message on the monitor?

Did you move the CPU and/or fan/heatsink when you were doing your rebuilding?

Does the motherboard have onboard video?

Reseat the video card?

Alright, I get the no signal after manually turning on the monitor because it doesn't get woken the plug is properly secured, it's an on board video card, all my plugs are properly secured with exception of one power not being used it is labeled p7 and was for a floppy drive, I know this pc worked prior to being disassembled I slowly and carefully removed the heat sink and then released the cpu then reseated and re-secured the heat sink on inspection all the pins are aligned and straight, none are missing or bend and the cpu seats well. the fan doesstart up though it is in a different position now. Thank you very much.

If you remove the heat sink from the CPU you need to clean the metal surface of the CPU (the heat spreader) and the heat sink and reapply thermal compound to the heat spreader before you reattach the heat sink. Without the thermal compound the heat sink may not be effective enough to ensure proper thermal convection which will lead to thermal shut downs of the computer. If the fan isn't in the proper position, this to can lead to thermal shut downs.

the pc doesn't have the opportunity to shut down from over heating, on initial boot it doesn't wake the monitor. Also when I do turn it on, I constantly check the heat sink for overheating.
