Help driver problems!

could be any number of things... Bad cable, intermittent connection, bad video card. . . not enough info here to diagnose the problem

Remove all the cameras then reboot. If it boots up normally then shut down dvr and add a camera and repeat. If it doesn't solve the problem, the issue is probably a video card or motherboard issue and will need to be repaired or replaced.

Press F8 key after post boot screen and before windows booting, dos screen will come from there select safe mede booting, computer will boot in safe mode

1) Click On start
2) Go to All programs
3) Go to Accessories
4) Go to System Tools
5) Select system restore

Sytem restore window will come there you will select restore my computer to the earlier time, you will get calender on the screen there you have select any highlighted previous date

After restart your computer will be ok.

there is something wrong with the video driver or the monitor...If the screen shows something like the devices when it boots up...and only goes blak when it logs to windows...I mean if you see all on the screen until you get to the windows logo..this is a operating system error ..a driver seting or crash...so ...just reinstall it ..or repair the operation system ..cause if it is a setting on video driver or a error ..you can not fix it if you do not see anything ..
if the system boots but you never see a thing on the monitor...not even the writen devices when it first starts..or the bios..this means that the screen or the ribbon of the monitor has a damage on..try to change its position...or so ..but in this case you will need a ribbon for sure ...

1) Restart your computer and when it's booting up press F8 and try and get it into safe mode.

2) Restart your computer press F8 and select last good configuration.

If methods 1 or 2 worked you can ignore the others.
NOTE: you might have to press a different F key then F8, but most times it's F8.

3) Get a hard drive enclosure and turn you internal hard drive into an external hard drive DO NOT FORMAT ANYTHING. From there just back up all your important data and return you computer to factory settings. (http://lifehacker.com/software/hard-driv…

4) Download Linux on a CD and use that as a live CD to boot up your computer and save your files. (http://lifehacker.com/software/disk-reco…

sounds like the internal video card is dying . have the service tech this out.

Boot in safe mode (press F8 when booting and select safe mode)
do a system restore to a few days back

START,, SYSTEM TOOLS ,, SYSTEM RESTORE
or
search it in the seach option in vista..

cause of problem,, driver crash..

Try to boot Vista into Safe Mode. Tap the F8 Key right after you turn on the computer until you get the Advanced Boot Up Menu
and use the keyboard arrow keys to select Safe Mode. The next screen may ask you to select your operating systm. Select Vista, not the Recovery Console.

Does your task bar and icons appear in safe mode? If so, it might be one of your start up programs that is failing and causing explorer.exe to fail during normal boot-up into Windows and not allowing your taskbar and icons to appear. Click Start and type in msconfig and hit enter then click the Start Up tab and look at all the programs that start up when Vista is starting up. Do Not uncheck anything in the list that you do not recognize as you may uncheck drivers or Vista starting programs that you computer needs to start up Vista properly. Google anything you don't recognize and uncheck any Start Up programs you do not need to start when Vista boots up, like Quicktime player or Adobe Reader for example. (This would also help your boot up time into Vista)

Sounds like explorer.exe crashed. Try opening up the Task Manager again, and Click File > New Task and type in explorer.exe. See if the task bar and your desktop icons appear.

If they appear for a brief moment then disappear again, the Windows explorer.exe is corrupted. Explorer.exe will try to start and then fail again. You may need to use System Restore to bring your computer back to a date and time when the computer was working properly, before the Vista update.

you can try pressing f8 to boot on safe mode, then try to set the video cards resolution to low, its possible that the resolution rate is set to high when the computer is booting normally thats why you get a blank screen, the video card cannot cope up to the resolution, or could also be the drivers for the video card you might need to reinstall an updated driver.
