Tell us the make and model of your brand name system, or if you have a generic desktop system, the make and model of the mboard.
The specific model of a brand name system is shown on a label on the outside of the case somewhere, or it can often be determined by going to the brand name's web site and loading a program they have available.
For Dell computers, they have a Service Tag number - the specific model can be determined by using that on their site, or can often be determined there automatically by you downloading some software. The Service Tag number should be on a label on the outside of the case, probably on the bottom on a laptop, on the back on a desktop, and is often also shown in the bios Setup.
The model, sometimes the make, of a mboard in a generic desktop system is usually printed on the mboard's surface in obvious larger characters, often between the slots.
Computer users often DO NOT install video drivers correctly.
Assuming you DID install them correctly, sometimes when you install video drivers, after you restart the computer, you get video while booting BEFORE Windows loads, but no video in Windows itself, because the specific video drivers are not detecting your monitor type properly, and sometimes you get no video at all in that situation.
Remove any bootable CDs or DVDs from drives.
Press F8 repeatedly while booting, don't hold down the key, and when the boot choices menu appears, choose
Enable low resolution video.
Your computer will boot normally except that the display will be forced to use default VGA settings that all monitors support.
RIGHT click on a blank area of the main desktop screen, choose Properties - Personalize - Display Settings - Advanced Settings - Monitor - Properties - Driver - Update Driver - Browse my computer.... - Let me pick from a list... - Next - choose (click on it to highlight it) Generic PNP monitor if it's listed - Next
( if Generic PNP monitor is not listed, click on the small box beside Show compatible hardware to remove the checkmark - Standard monitor Types - choose Generic PNP monitor - Next)
(OR - if you have the CD that came with the monitor that has the specific drivers for the monitor, or a download that has the specific drivers for the model, click on Have disk lower right, Next, and go to where the drivers are - Windows is looking for an *.inf file. NOTE that if the monitor is LCD or Plasma, you should load the specific drivers if they are available, because you can choose settings in Generic PNP Monitor mode that can DAMAGE the monitor ! )
Close (or if you chose specific drivers, if there is a list of models, choose the correct one, etc. )
click on Close on the Driver window.
click on OK on the Monitor window.
click on OK on the Display Settings Window
close the Personalization window.
When you Restart or start the computer normally after that, the subject monitor should display fine in Windows.
Computer users often DO NOT install video drivers correctly.
When you install different video drivers from what you were using, usually you are supposed to un-install the previous video drivers BEFORE you install the "new" drivers.
Sound and video "drivers" always have associated files that must be installed properly along with the actual drivers. If you install only the actual drivers, it's likely the device will NOT work properly.
Unless the instructions for installing a device tell you otherwise....
(this ALWAYS applies to video and sound adapters )
You DO NOT install drivers for a device while booting into Windows, if the software for the device has not been installed yet - when Windows detects a generic device or New Hardware while booting, you allow it to search for drivers, it doesn't find any, and it wants you to show it the location of the drivers - CANCEL that, continue on to the desktop, and install the software for the device using the proper installation from a CD or the proper installation file that you downloaded from the web.
The same applies no matter when Windows finds New Hardware !
If you DID install drivers that way,
(The following also applies if you want to un-install previous software, or re-install the software)
- for video "drivers"....
- go to Control Panel - Classic View - Programs and Features - and Un-install the software you installed, reboot, DO NOT install drivers while booting, let the desktop screen fully load.
Install the video software properly by running the proper download you got from the web, or if you have the CD that came with the video card that's in a slot, or if you have the CD that came with the brand name computer that has the Drivers on it, run the video software installation from the installation program on that.
You DO NOT need to load updated video drivers unless you're having problems that are definitely caused by older drivers. If there is nothing about your problem mentioned in the release notes for the video updates, or mentioned in the known problems or similar list, on the maker of the video chipset's web site, updating the video drivers is extremely unlikely to hep.
I DO NOT recommend you get updated video drivers from Microsoft's Windows Update. You are more likely to have problems if you load those. If you see a listing there and you want to load undated video drivers, go to the web site of the chipset maker and get them.
If the video drivers are for an ATI video chipset, if ATI's Catalyst software is also installed, which is the default, the video drivers version must be one that is matched to get along with the Catalyst version you are using. The video drivers version changes more often than the Catalyst version.
Having mis-matched video driver and Catalyst software versions won't likely cause no video in Windows, but can cause other problems.
You can check on the AMD web site to see whether your changed video drivers version has the Catalyst version you're using listed along with it,
- Un-install BOTH the present display drivers and the Catalyst software in Control panel - Programs and Features, and install the default combo display drivers and Catalyst version you get from the AMD web site.
