As with most computer errors, your first step is to shut down your computer and restart it. This will help you determine whether or not you actually have a hard disk problem. If the disk is severely damaged then your computer will probably fail to restart properly or would be behaving erratically. If this is the case then contact ProICT

Verify that your computer is able to see the Internet and/or other computers to ensure that your computer is not having connection issue. You can test this by opening a random webpage. Make sure that your Internet e-mail server or your Network e-mail server is not encountering issues by contacting either your Internet Service Provider or your Network administrator.

A computer virus is a type of computer program that has been intentionally created, when executed, replicates itself by modifying other computers programs and inserting its own code. Motives for creating these viruses usually include seeking profit, a desire to send a political message etc.
To help prevent a computer from becoming infected by a virus, software developers have developed anti-virus programs that are constantly active on computers assisting to project it. With Windows 10, an anti-virus program comes pre-loaded but sometimes a more robust program is needed.

Verify that your network cable is properly connected to the back of the computer. In addition, when checking the connection of the network cable, ensure that the LED’s on the network are properly illuminated.
For example, a network card with a solid green LED or light usually indicates that the card is either connected or receiving a signal. Note: generally, when the green light is flashing, this is an indication of data being sent or received.
