Replacing a video card in a personal computer refers to the operations that every owner of the computer system must be able to perform. Otherwise, the user may be dependent on the service centers. And since the replacement of a video card usually does not present any complications, such a request for help is obtained not only unpleasant, but also irrational.
The novice user, who for the first time opened the case of the case of the system unit and peeked inside, is likely to be amazed at the abundance of electronic elements, boards and confusion of wires. For this quite understandable reason, it may seem that the replacement of a video card is the prerogative of electronic specialists, computer scientists or programmers (although the latter, rather, is a stereotype). However, this is a delusion. Since those distant times, when the serial production of semiconductor computers was started, their design provides for a simple modernization of many constituent elements. In the development of computing systems, a block principle was used: the entire construction was assembled from functional blocks-components. It is quite appropriate to compare with children's cubes or the Lego constructor. Thus, the replacement of a video card does not require the ability to handle a soldering iron or understanding the operation of electronic logic circuits.
Before specifying the order of actions, we note that the replacement is possible only for discrete video adapters, that is, those that are represented by a separate board. Integrated solutions are not directly replaceable.
Turn off the power to the computer, remove the plug of the monitor's power cords and The system unit from the socket. This is necessary, since it is not known what exactly the extension button breaks - zero or phase. Unscrew the two screws from the back of the case and remove the side cover. The graphics card is easy to recognize - it is inserted into the motherboard connector and a wire from the monitor is connected to it. Disable this wire. We unscrew the screws that hold the card. Carefully remove it from the connector: first a little one side, then the other. The connector can be a mechanical latch - it must be unlocked. The new card is inserted in the reverse order: first into the connector, where it is securely fixed; Then the monitor wire is connected to it. Two points: excessive effort is not required at any stage; The comb of the sliding contacts must be evenly "hid" in the connector.
Replacing the video card on a laptop is a little more complicated. You must turn off the power and remove the battery. Unscrew the screws holding the bottom cover of the case. Remove the cooling system (usually heat pipes). Video card Is connected to the connector and fixed with two screws. We unscrew them, remove the headscarf from the connector. In its place, we set a new one. It is desirable that it was the same manufacturer and similar class.
But the replacement of the video card in iMac involves a lot of difficulties, and not at all technical. Theoretically, you can change the map, but this will require:
- choose the model of the desired form (the usual will not work);
- Make sure that the components are consistent (there is a possibility that a more powerful card simply will not work).
It is recommended to initially purchase an iMac with the desired characteristics.
