So, i have a Toshiba laptop with windows vista and recently i busted the screen. so we hooked it up to a Dell computer screen, so we could still use it. It was working fine, but recently, when i turn it on, it will load and then this screen comes up thats says "windows was not shut down properly" and gives me the options to start windows normally, safe mode, safe mode with networking, or safe mode with command prompt. when i start windows normally, it will load, but instead of going to the log in, the screen will just go black. But it will run with i run it with any of the safe modes. Anybody know how to fix this?

For — quick, focused troubleshooting to narrow this down so work doesn’t start with a trip to a shop. The key observation is: Safe Mode + external monitor work, but a normal boot goes black. That strongly points at something the regular Windows session is doing (display output, shell or startup item) rather than a plain-power/BIOS display fault — but hardware can still be the cause if software checks fail. Try the steps below, in order.

  1. Verify POST/BIOS: connect the external monitor before powering on. If the vendor logo/BIOS screens appear on the external, the video path is present and the problem is inside Windows; if BIOS never appears externally, hardware is more likely.
  2. Recover the desktop if possible: at the black screen press Ctrl+Alt+Del → Task Manager. If Task Manager opens, use File → Run new task and enter explorer.exe. If the desktop returns, focus on startup items.
  3. Clean-boot isolation: boot Safe Mode, run msconfig, on Services check “Hide Microsoft services” then disable the rest; on Startup disable nonessential entries. Reboot normally. If desktop appears, re-enable groups of items until you find the culprit.
  4. Force output to the external monitor: use the laptop display-toggle key (Toshiba models commonly use an Fn+Fx key). On newer Windows versions you can also use Windows+P to cycle modes. Try this at the black screen.
  5. Make Windows use only the external panel while testing: in Safe Mode set the external as the primary display or temporarily disable the internal LCD in Device Manager (create a restore point first).
  6. Cross-check with external OS: boot a Linux live USB or Windows install media. If the external works there, it’s a Windows/config issue; if not, hardware troubleshooting is needed.

If software steps don’t help, gather what you tested (BIOS behavior, live-USB result, whether Task Manager opens) and then consider professional hardware diagnosis. This builds on the software vs. hardware suggestions made earlier by and : start with the inexpensive software isolations before moving to hardware fixes.

This sounds like a driver issue to me.
First, from safe mode, go into device manager and roll back your driver, then restart.
If that doesn't work,then you can try this:
(Installing clean drivers)
Enter safe-mode-with-networking and download a clean driver package from the Toshiba web site, then remove the existing driver and restart. When the system restarts, cancel the automatic driver installation and instead install the new driver that you downloaded.

HiThere are several various reasons for your screen to fail etc, some links to the graphic card and other link to the bulb that lights the screen/ CCFL backlight failure and a dead inverterhttp://www.laptop-junction.com/toast/content/laptop-screen-flickering-hissing-and-black-spot-cornerhttp://www.laptop-junction.com/toast/content/dell-latitude-d610-screen-suddenly-goes-black. LED screens don’t have a fluorescent tube try to download a new driverorshut down the system, unplug it, take the battery out and press ON button for 30 sec, then release the finger and wait another minuteGet into the power settings (under screen saver) and check the settings for running on battery and running on AC power
or you can put a new bios

sometime adding a new CMOS battery or resetting CMOS can solve the problem. but with all computers and laptops it is a proccess of elimination
and sometimes the smallest thing can create a major problem
