can i change the graphic controller in my pc?

Answer 1

Yes it is possible to change your graphics controller - though you will find most will refer to it as a "graphic card" or "video card". Firstly, lets determine what type of PC you have:

If you are running a laptop, I can almost certainly say no - as laptops are meant to be a low profile type of computer, therefore, have a very limited expansion ability. There are exceptions with certain high end laptops, but this would involve soldering it to the motherboard, which I highly do NOT reccomend.

If you are running a desktop PC, you are far more likely to be able to do something about the graphics card than a laptop. For this we need to determine your operation system and available expansion slots:
----------------------------------------------------------------------------------
If you are running Windows 95, you won't get very far in obtaining an adequet graphics card, so there really isn't any point.
----------------------------------------------------------------------------------
If you are running Windows 98, then you could probably get a fairly suitable card for your needs (we will move onto this later).
----------------------------------------------------------------------------------
With Windows 2000 / XP, you should be able to obtain a pretty good graphics card, as they are fairly recent operating systems.
----------------------------------------------------------------------------------
With Windows Vista, you'd think you'd be able to get the widest range of graphic cards. This isn't actually true (for the time being anyway) as Vista is currently a very buggy operating system, and many people are experiencing issues with installing certain hardware and software on it. I do not own Vista, so I can't give you an exact story, but seeing as Vista requires at least 128mb of Video memory, you should be experiencing a fairly good graphical experience on it anyway.
----------------------------------------------------------------------------------
If you are running a Macintosh, there are cards out there, but I know nothing about them so unfortunaelty I can't comment =(
----------------------------------------------------------------------------------

Now we've sorted that (I hope), we need to find out what type of slot your PC has. This will be one of three which are:

* PCI
*AGP
*or PCI-Express (also known as "PCI-e").

To find out, you can either check the system hardware tab, or the easier way is to open it up - which you'll have to do anyway.

PCI slots are generally rubbish for gaming, however there are a few decent cards - such as the Nvidia 6200, that will do fine for media users. They will look like a long white slot near the rear of your system (inside).

AGP slots are very capable ports that can handle todays graphic power. You can reach around Xbox 360 graphics with these (if that helps). These slots can come in various colours such as orange, blue, red etc. They look a bit like PCI slots, except they will be situated further back on the motherboard.

PCI-e slots are pretty much always black - whcihc is usually how they are recognised. Again, they are situated further back on the rmotherboard. This is the highest end slots on PCs currently. They are capable of next-gen graphics, and can overpower a PS3 with ease if using their most powerful cards - such as the Nvidia 8800.

Our final objective is to choose a graphic card. So long as you know your slot, you should have no problem finding one. One crucial note before you do this though, is to check your PSU's (power supply unit) wattage. This is simply done by opening your PC and reading the label on it. The PSU is situated as a brick like case on the top of the rear of your PC. If you can't find this out for any reason, try phoning your computers manufactuer. They will be able to tell you its capability. Whilst your talking to them, you may as well also ask what graphic cards are good for your system.

When it comes to purchasing your graphic card, it can be very daunting. This can be overcome with these sources:

1) What do you use your PC for?

If it's for merely browsing the web, e-mail, word processing etc, you won't need anything else than what came with your system.

If you want to watch video and play music, you'd be looking at a media card. These typically range from £40 - £60. Try not to go in excess of £100 with these.

If you're wanting to play games, congratulations - you've just discovered the most expensive line of cards! These can often range from £200 - £400 depending on their capability.

2) Also note these prices are retail prices, and can probably be found much, much cheaper on the likes of Ebay.

3) When you come to purchasing your card, don't just pick up the nearest 512mb expecting enthusiast performance. If it's cheap, it's likely it performs that way too. If buying from a store, then I suggest asking staff for assistance. Tell them your needs and they will be only to happy to assist. If you use a website, such as Ebay, I suggest reading up about average card specs, as there's only so much I can tell you. Try to avoid second hand cards too. These can sometimes come faulty and have a shorter lifespan than new ones.
--------------------------------------------------------------------------------
Now finally, after buying you new graphics card, you merely plug it in, install the drivers (the thing that makes it work) off the CD, and enjoy. If you feel uneasy about installing it, perhaps use a site guide, or get a friend help you. Either way, don't go paying for anything - as it really is a simple job.

I hope this helps you with your purchase.

Answer 2

There are two types of Graphic Controllers.

a. Those which are built in on a mother board and
b. Those which fix in to a slot available on the board.

You can deffinittely change the ones that are not built in on a board, but connect through a slot.
