What to do when your computer refuses to connect?

Yesterday your computer was functioning properly. But it was enough to change it to a place he did not call back. The problem may be related to some component that broke off during handling equipment.

Abet the office during a change especially when using a car for this task can disconnect some components of their corresponding slots.

Solving this problem is not complicated, even for those who have little knowledge about the physical part of the computer (hardware). Some basic care and a little attention can solve the fault.

Ground: Several of the components inside your computer are extremely sensitive to electrical discharges, even from static electricity. Therefore, before opening the case where the CPU, move it to an area without carpet. If you have a wrist strap, put it, otherwise touch any metal surface that has contact with the ground or a wall. This will ensure that any static charge your body may have accumulated will be discharged. With the device unplugged, open the cabinet, removing the screws (if any) or moving the existing barriers.

Look for something out of place: A general survey may indicate something strange - loose or disconnected cables or an empty slot (that was not already before). In general, there should be no wires left in the cabinet, if it finds one, the chances of it being the cause of the problem are large. In almost all cases, there are connectors that can fit in more than one place. Therefore, locate the point where it broke off and reconnect. Check the cables that are apparently in place, the movement of the cabinet can have a little they undocked, but not enough to get him completely from the connector.

Check the PCI and graphics cards: Unscrew each PCI card (include those who have a door facing the outside of the office) that exists in the PC and the undocking of the respective slots. Replace each one carefully (there is usually a 'click' when it is in the correct position) and tighten the screws again. In the case of graphics cards (GPU) and memory cards, there may be a plastic bar fixing that needs to be undocked and raised so that the component can be removed. Unplug and replace them in place (you can also hear a click when the snap happens). When handling components, look to hold them by the edges, preventing any oil that may be in your hands can achieve some important item and damage it.

Before: a plate with a component shifted
Then add the same component reattached

Reseat the RAM modules: Most motherboards releases the memory modules if you press the lever located on the sides of these modules. Do this and the RAM will undock. Let the levers open when removing the RAM. To dock it again, push the RAM module down, without using too much force to fit the memory again. You'll see the levers back into place. Remember to never force the plug-in component of any PC.

Close the CPU and try to connect your PC: If the problem persists, remove the power cord from the outlet, open the cabinet again and remove all components that are not native to PC (eg, PCI cards, GPU and memory modules, additional ). Close the equipment and connect it again. If the product works, the problem is related to some of the components removed. Replace them one by one and connect the equipment to each item added to find out what is the problem, replacing it with a new one.

Problem disk: Another fault that can happen due to careless transport of the office is the hard disk (HD). Although newer models have technology that prevents damage to them - when the product off the heads of read / write is collected for a position that prevents q physically touch the disk during transport - the HD can be damaged. In this case, the PC can connect to, but can occur error reading the disc and thus the operating system will not load. If this occurs, try booting the PC with another hard disk that holds the operating system installed, and - if the disc problems can be read, back up (if no problem with the disk) and format it and reinstall operating system and applications and copy your data to it again.
