Primary monitor does not work after last nights updated

  • I'm running Ultimate.
  • I have two monitors.
  • My primary monitor does not work.
  • I checked the VGA cables. This isn't the issue.
  • Edit: Just realized that my main monitor is a monitor "Westinghouse". -Who is a "Plug-in-and-play" monitor, there are no drivers.
  • Reinstalled the ATI drivers, did nothing.
  • SYSTEM RESTORED, still nothing.

I ran the most recent update for final last night, then fell asleep. Everything worked before that date, but when I went to turn on my computer this morning, only my HP [my second monitor.] w17e worked. He said he was installing updates from last night, so I had no problem with him and thought it might show something once like this on the login screen.

Once that has happened to the login screen, it showed it for a fraction of a second before disappearing. I entered my password and it connected as usual. After login, I turned off my monitor, and then back on, and it showed my normal desktop for a moment, [enough for me to close two-three programs] before she returned empty.

Hello
 
I recommend you to update the graphics drivers and see if it makes a difference. You must be logged on as administrator to perform these steps.
 
1. open Device Manager by clicking the Start button, click on the Control Panel, clicking system and Maintenance, and then clicking Device Manager. If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.
2. in Device Manager, locate the graphics card and then double-click the device name.
3. click Driver tab, then click on set to update driver and follow the instructions.

Now, try to follow the link provided to update a hardware driver that is not working properly and check the question below.
