A video card, no matter what the application, is quite the investment and sometimes, it can set you back a few thousand of dollars as well, depending on what sort of application you are using it for. When you are making that sort of purchase, you would want everything to run correctly, and the last thing you would want is for you to come back and install the video card, only to find out that the thing doesn't even work, or worse, it has affected the rest of your priceless computer.
Now this is worse when you are using the video card for your work, because any amount of downtime would be costing you money that you do not want to waste in the first place. So what do you do when you do find yourself at the foot of your computer looking at a screen that does not make sense to you. Well, it would surprise you to know that the video card problem is one that is quite common around the world so what you need to do is to first of all not panic. This is the first step of any sort of disaster management that should be followed, keep calm and know that there is a rationale and very technological solution and answer to this problem.
Doing the same thing over and over again or trying to be a genius when you are not will not solve anything, and if anything, it will make things much worse then they really are. What happens is that most likely there is a conflict with the video card and the computer operating system and most of the time, it is the driver that is at fault. All you need to do for the second step is to check whether or not there is a problem with the version of the driver that you are using and see if you need to change it.
Some rare occurrences would deem that you might even have to downgrade the version of your driver, but it is more than likely that the driver needs to be upgraded and these companies often test their systems and solve conflicts by adding another layer of architecture into the driver and updating the set of instructions inside. Once you have established that it is the problem, and 99% of the time it is, all you need to do for the third step is to download the latest version of the driver from the internet and of course installing them.
Make sure that between the second and third step you check against the forums or tech support centres against the version of the card and the sort of system that you are using. It sometimes is not so cut and dried as just renewing the driver and it could be a much deeper conflict than it is. But most of the time, this is a condition that is quite rare and does not happen very often.
