Hi,

My daughter's laptop will boot up and let me enter password but as soon as password is entered the screen remains black, then after a while a screen appears with writing (very quickly so I can't read it) and then it reboots the laptop again. Before it reboots if I ctrl, alt, del and start a a new task it will let me access my pictures or even go on the net..Can anyone please help me?

Hello,

Try this 1.

1) When you switch ON your computer, start tapping the "F8" key to get

"Windows Advanced Options"( if boot menu appears, press "Esc" key and keep

tapping the F8 key)

2) Select "Safe Mode with Networking"

3) Click on Start --> Run --> type regedt32 and press Enter.

[If you are using Windows XP or Windows 7 then

Click on Start --> In search box, type regedt32 and press Enter.]

Registry Editor will be opened. Navigate to the following location

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon

At the right side, find the strings shell & userinit and check the following

shell value data should be
Explorer.exe

userinit value data should be
C:\WINDOWS\system32\userinit.exe,

If shell and userinit are having different data values then change it as mentioned

above.

Just double click shell and userinit and enter the data values as

shell --> "Value data" should be
Explorer.exe

userinit --> "Value data" should be
C:\WINDOWS\system32\userinit.exe,

Note: there is "," at the end of userinit.exe

Then download "Malwarebytes' Anti-Malware" from the below link.

Update it and perform "Full Scan"

Note : Default selected option is "Quick Scan"

Good Luck.
