Black Screen after "Windows is Starting"

post #1 of 6
Thread Starter 
When I turn on my PC its posts, shows the "Windows is starting" screen, then loads a black screen with the mouse icon. I can move the mouse around just fine, but when left for ver an hour, the screen continues to stay black. Dont be confused, the monitor is on and displays the cursor. Here are the steps I have tried so far.

1. Hard restart
2. Resetting BIOS to defaults
3. System Repair (found no issues)
4. Removed CMOS for 5+ minutes w/ power supply unplugged and switched off
5. Disabling graphics card and using onboard GPU

Puzzling issue: Unfortunately the only System restore available was yesterday night, when I left the system for over an hour when I saw the black screen on boot. Which tells me that the system is running fine in the background. Tried to restore it anyway but didnt help the issue.

Puzzling issue: When system is booted (to black screen and cursor) and I press the power button once, system shts down normally, which proves system is running normally in the background.

Im assuming this is a windows issue. I am running Win 7 on 2 240GB Neutron GTX SSD RAID 0, i7-4770k, Z87 Sabertooth. Complete rig in sig.

I really don't know what to do from here. First time using RAID 0. Had issues in the past, but I assumed it was because I didnt install the RAID drivers during OS install =D. Since then I reinstalled OS + RAID drivers and have had no issues.

Last thing, I have on occasion noticed stuttering as soon as OS has loaded in the past.

Help would def be appreciated!!!

cntrl+alt+delete / task manager / file / new task / Explorer.exe


it sounds like explorer.exe isn't starting on boot.



1. Let's first start the computer, once the comp boots to the desktop, press Ctrl+Alt+Shift to bring up Task manager
2. Under Processes tab, check if the explorer.exe process is running
3. If it's not, then cilck File-> New Task, type explorer.exe and click OK.

Once it is done, check for these steps:

Start > Run , type in 'regedit' (without the quotes of course) in the search box .


(can also get run by going Ctrl+Alt+Del>file>NewTask (run))


Go to the following in the registry editor:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon.

In Winlogon, on the right side, there should be a value called "Shell".
Double click this value. Make sure only 'Explorer.exe' is the value of Shell, if anything else is there , simply delete it and leave 'Explorer.exe' .
Restart the computer for the changes to take effect.

Thanks for your reply! Unfortunately nothing happens after ctrl+alt+del. I do notice the mouse freezing very few seconds hen continuously moving it around the screen. similar to the stuttering I was seeing before this issue arose.

    I thought I would add another possibility in case someone else comes across this thread: I have experienced Windows sometimes fail to load the DeviceGammaRamp for the video card correctly.  Sometimes this causes the screen to be very, very dim, or even black, while the mouse cursor remains at full intensity because it is an overlay.  However, it has always been a fluke for me, and simply rebooting (or pressing the standby button on the keyboard and then waking the computer back up) resets it for me.

    If you can log in without having to see your screen, one way to tell if this is the issue is to move the mouse where there should be desktop icons.  The mouse pointer should turn to a "hand pointer" each time it is over an icon.

    I have also experienced this upon "unlocking" the computer, when the screen should fade to the desktop, sometimes fades out and doesn't fade all the way back in, leaving the screen very dim (or black) with only the mouse cursor displaying correctly.  I wrote a simple program that can modify the current DeviceGammaRamp (for quick monitor calibration), and when I can see well enough to start it, the screen comes right back to full intensity when I hit the [Reset] button.  Thankfully, the problem seems to have gone away, probably due to a video card driver update. thumb.gif
