As computer programs become more sophisticated and more resistant to viruses, computer hardware is nowadays more likely to break down. Hardware failures can cause a computer to run slowly, stutter, reboot, or shut down completely.
Technical computer repairs can be divided into the following steps:
1. Technical diagnostics of computer components
All internal components of the computer are tested:
- hard drive (HDD) – the most common faults are bad sectors, but the drive’s control electronics often fail as well;
- RAM modules – bad or non-working sectors can also occur in RAM;
- processors (HDDs) may have damaged feet due to improper installation, malfunctioning or improper cooling, or damage to the connector due to overheating;
- power supply unit (PSU) – if the computer still works at all or only turns on after several attempts, the capacitors are usually faulty, but if the repair is not carried out in time, the transistors fail as well, which makes the repair more expensive, because a part has to be replaced with another one, as repairing the existing one becomes economically unviable;
- motherboard (MB), also known as the mainboard – contacts may be damaged by corrosion, bridges may be overheated, the CMOS / EEPROM may be faulty, or there may be problems with the integrated video chip (BGA)
- optical drives (ODDs/CD/DVDs), usually with a weak laser;
- video card (VGA), overheating problems are the most common, and corrosion damage may also be present;
- For laptops, additional testing includes screens (arrays), wireless connectivity (WiFi), sound card, speakers, keyboard, touch pad (touchPad), charger (power supply), camera.
2. Search for details
Once the computer parts to be replaced or repaired have been identified, an estimate is made in both cases. In the case where a part is being considered for replacement, the options for replacing the part with both new and used parts are assessed. An estimate of the repair work shall be established.
3. Making repairs to a technical computer
Alternative estimates are provided by the customer. Risks and probabilities in all cases are identified. Decisions are made and bad computer components are repaired or replaced.
Repairs usually take a few working hours. Longer waits are required when parts are not available locally and have to be ordered. We try to have the most popular parts on site to make repairs as quick and efficient as possible.
