|Sometimes when you install video drivers or updated video drivers, the video drivers don't detect the monitor correctly the next time you boot the computer, and thereafter. In that case, the video is normal while booting until Windows is supposed to start to load, then you either get basic VGA video in Windows, or no video at all in Windows. |
There's probably nothing wrong with the video drivers you installed, unless you installed them incorrectly.
See BELOW at the end of this post regarding installing them properly.
You need load the proper monitor drivers.
NOTE that if you get no video at all in Windows when you boot normally, if you press F8 repeatedly while booting and select Enable VGA mode, you can install the monitor drivers in that mode just fine, then the monitor will display in Windows when you boot normally. You probably can't do that in Safe mode, and you often can't un-install or install video drivers in Safe mode, but you can in Enable VGA mode.
Monitor drivers (and Manual) 933SN
I downloaded the drivers - it appears you just double click on it, it will install the drivers.
The monitor drivers are also on the CD that came with the monitor.
If you have only basic video, or no video, in Windows when you boot normally after the monitor drivers have have been installed, they're there, but you need to go through some steps to get Windows to load them.
Ask me how.
"....theres alot of purple vertical line on the screen."
If you get the lines BEFORE Windows loads while booting the computer, or only get lines AFTER the monitor and the computer have warmed up, that can't be caused by any software problem on the hard drive - there's either
- something wrong with the monitor or it's video cable connection.
- if you have a video card in a slot the monitor is connected to, it has a problem.
- if it only happens AFTER the computer has warmed up, if your video adapter is on a card in a slot, your video adapter chipset is probably overheating. Unplug the computer, or switch off the AC power to the computer. Open up the case. If it has a fan and/or heatsink, check them/it for accumulated mung (dust, lint, etc.) - clean them/it if that's found, but DO NOT use a vacuum cleaner to to do that ! Make sure the fan spins okay when the computer is booted (later on, when you still have the case open and have restored AC power to the computer). Make sure the card is all the way down in it's slot.
Restore AC power, try the computer for a while.
If the monitor produces no lines when it's connected to a different computer, then the problem must be caused by a problem with your video adapter.
Problems with video drivers rarely produce lines that aren't supposed to be there, and even if they did, they would not produce them all the time.
How to Run a Monitor Self Test
Unless the instructions for installing a device tell you otherwise.......
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 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.
If you DID install drivers that way, go to Control Panel - Classic View - Add/Remove Programs and Un-install the software you installed, reboot, DO NOT install drivers while booting, and install the software the right way !
