The most common PC problems can usually be resolved on your own. This will save both time and money. Therefore, do not rush to go to the service center and familiarize yourself with the most common problems with your computer, in the event of which you should not panic.
Computer won't start
Typically, this problem is associated with a lack or lack of power supply. Check the source of electricity and the computer's connection to the network. If you cannot start, check that there is no problem connecting the computer to a different outlet and other device (if using a stabilizer or filter). A voltage indicator is mounted on the motherboards. Remove the left cover of the system unit and check if the indicator is on. If it does not light up, replace the power supply first.
Screen is blank
One of the main reasons for such a problem is a violation of the connection between the system unit and the monitor. Make sure the connection is correct and the monitor is plugged in. If you have a laptop, you should contact a specialist, as the cause of the malfunction is usually worn wires laid inside the case.
Another reason may be incorrect functioning of the operating system or software. Press Ctrl + Alt + Del, in the task manager select "New task / run". Enter explorer.exe and click OK. If the contents of the desktop are displayed, then check the computer for viruses, and the registry keys for validity. If Windows does not boot, use the recovery disc.
Computer freezes
In this case, the only way out is a reboot, in which there is a risk of losing unsaved data. The hang can be caused by a lack of RAM, overheating of the processor or hard disk, as well as video cards, damaged or missing files, or virus activity. Clean the inside of the system unit, fans, radiators from dust. Go to the "Properties" menu in the "My Computer" section. Then, sequentially click "Advanced" - "Startup and Recovery" - "Options" and uncheck the box to automatically reboot. If a blue screen appears, rewrite the error codes. Check your computer for viruses.
The computer is slow
Clean up unnecessary files from your hard drive. Use external hard drives to store your files. This will free up additional disk space for the needs of the computer's operating system. Turn on regular registry scans. Make sure your computer has antivirus and firewall software installed and operating.
Extraneous sounds
Check the cooling fan for proper operation. In the event that the fan is working normally, then extraneous sounds most likely indicate a hardware failure. Hard disk failures are often noisy, so do a backup procedure.
