Possible computer faults and repairs

Repair options and solutions: when a computer does not turn on completely, it may be a sign that the power supply of your desktop computer is faulty. This is a common and quick-fix fault. Replacing the power supply takes just 5-15 minutes, so if you contact a computer technician in a hurry, the problem will be solved quickly. However, sometimes there can be more serious problems, such as motherboard or processor failures, which require a longer repair time.

In the case of a laptop, if it doesn't turn on, it's a good idea to check the power adapter, disconnect and reconnect the battery, and press the CMOS reboot button on the bottom of the computer, if there is one.

When the computer starts up but the screen remains blank and there is a beeping sound inside the computer, this indicates a technical fault with the computer. This could be a problem with the memory (RAM), the video card (VGA) or the motherboard. The repair in this case depends on the nature of the fault, but if the RAM or VGA is broken, the repair is usually not long.

If your computer starts up but stops at a certain message or keeps rebooting, it's usually related to the hard disk drive (HDD). It may be that the system cannot find the right file or the settings in the BIOS. In this case, you should contact a specialist or use the advice given in the article on recovering HDD data.

Sometimes the computer won't boot because of a connected USB stick or other external media. The BIOS system may first turn to these devices and, without detecting the necessary files, cannot boot. The problem is solved by disconnecting the USB stick or by changing the BIOS settings to the correct first boot device.
