Windows 7 Ultimate x64 Black Screen [fix]
So after working to the early mornings on my 6th and final assignment for first years, I awoke to find my macbook pro would no longer display the desktop, normally any movement of the mouse or a keypress and the desktop would fire up instantly, not today. I could see that the hard drive was still on and the keyboard lights had come on, the differences I noticed were that the famous Apple logo behind the monitor did not illuminate and of course the screen was black. I forced a reboot and jumped back into bootcamp, the windows logo would appear and then I would see the black screen. What has happened I thought.
I retried again this time booting into Mac OSX, things were ok here. Next I tried booting into Windows safe mode and I was able to get in and the screen desktop appeared. So again, I tried normally booting and the same issue remained.
Back into safe mode I decided to check the event logs. Looking for anything unusal I started in Applications. I did not identify anything in Applications so I continued looking in System. Here I noticed a repeated bunch of Adobe Flash issues suggesting shutdowns had occurred, as they were reoccurring logs I dismissed these as the issue causing the black screen. I continued scouring the logs further and I found an entry that suggested an automatic update had occured at around 3:30am.
The entry was deemed critical and automatic:
Windows Defender automatic update KB15597 (Definition 1.139.936.0)
As this time was during my absence from my computer and after the last time the monitor was working correctly, I concluded that this event was deemed important, so I decided to run a system restore in hope to get Windows back to its previous state. Firing up system restore I found that a restore point had occured at exactly the same time the update had been logged in the event log. So things were looking promising.
As see from the screen above, I chose the 3:27 restore and let windows do it things. After waiting about 3-4 mins, the system rebooted and I got back into bootcamp, the windows logo appeared again and after it disappeared the win logon did appear this time and the screen was no longer black. Woohoo!
