I have a Windows 7 Pro 64x SP1 machine that "sometimes" hangs on startup after the Windows splash screen with nothing but a black screen and no cursor. It will start up in Safe Mode OK. Sometimes it boots up just fine and other times I get the black screen.

This first started after some Windows automatic updates. It seems to happen more often after a complete power-down. I have left the black screen up and walked away for an hour and it never boots - no HDD activity, nothing...

Things I have tried:
1) Memory check for bad RAM - all OK
2) chkdsk - no problems
3) All drivers up to date
4) Virus checked whole computer scan - no issues

The only thing that seems to work is booting it into safe mode and then rebooting Windows normally. It is a real pain.

Ideas and things to try would be greatly appreciated.

Thanks,
Kerry

If this helps in any way, I'm also getting these black screens once in a while, eventually if I wait long enough it'll boot up but it's annoying.

Hopefully it's not just us two though

It's time you take a look at everything running and starting up when your computer does.

I would recommend using Autoruns.

The #1 cause of long (or slow) boot times is either something starting (or attempting to) when Windows boots or an external device (i.e card reader, webcam, flash drive, printer w/card reader) that is plugged into the computer itself.

For both of you all having the issue, try these things and see if it helps:

  • ■ Unplug everything that is non-essential from the computer itself. In most cases, this is everything but the mouse and keyboard (or if the receiver is USB leave it in), monitor (you gotta be able to see what you are doing), power cord, and network cable (or however you are connected). Be certain that the computer is turned completely off before doing this so that it doesn't maintain any unneeded drivers, etc. Once done with that, turn the computer on and see if you notice a difference in the boot time. It's best to typically do a full shutdown and restart for a series of 3 attempts in order to give a good basis. If you are able to boot fairly quickly after two attempts, there is no need for the 3rd.
    ■ Try putting your computer into a clean boot state.
    - Detailed instructions on doing this can be found HERE.
    Once finished doing this, see if the issue occurs during a clean boot. If not, then there is likely something causing the hang-up that has been disabled during the clean boot process.
    ■ If it is something that has been disabled by the clean boot there is a way you can identify it or even disable it from running at all.
    I would recommend using Autoruns.
