My laptop freezes on a black screen, i.e., the screen turns off but doesn't come back on after installing new Windows update, Windows 7 SP1 is what I think is causing it.

I've run the Windows start up repair and it gave the reason of a "bad patch" as the cause of the problems.

I've reverted to a restore point just before I updated so it's working now. But what I'm wondering is how do I stop this from keeping on happening as I've tried to update it myself a few times before posting this, and the problem happened every time.


I've foound a question that is the same as mine but only gives the restore option, but no solution to the problem.

No display after boot on windows laptop after update

  • Which update exactly causing this problem? Aug 7, 2013 at 20:41

    After years of delaing with Windows, I'm of the strong opinion Windows updates don't break Windows, when it seems they have, it's actually them just revealing another problem. Having said that, dumping 100 patches plus a Service Pack all at once doesn't always go so smoothly. What is the full/exact error Startup Repair presents (including Problem Signatures, etc.)? When you attempt to apply patches one at a time, how far do you get? Aug 7, 2013 at 20:46
  • Short of any more info on the error message, try to isolate the problem as much as possible. Are you only installing the service pack or are you doing other updates as well? Try updating your graphics card drivers or trying an older version if you can, and then reapply the update. Can you boot into safe mode before the black screen?

  • @techie007 Its just the service pack that causes the problem, I can't remember the problem signature, it could have been 0xa (that's the only one that i can recall that wasn't 0x0). I looked up the update history and the only one thats failed is sp1

Generally I refrain from doing any kind of driver updates that Windows update throws in the "Optional" area. I find these cause all sorts of driver issues that cause anything from no display or bluescreens.

  • there was optional ones thrown in with the sp1 update, but even when I've done them seperatly they done't cause any problems, its only when I install the sp that the display doesn't turn back on.
