Computer errors are very common and every computer user may face different kinds of issues so they should learn about the solutions of the common computer related problems. The common factors that cause problems in computer are viruses, spyware, Trojan horses, adware, corrupted registry, faulty hardware, low memory, low capacity hard disk, low CPU speed and stuffing computers with large number of software applications. In this article, I have compiled a list of the most common computer problems and their solutions.



Computer is very slow

This is very common issue and it arises due to the several factors such as too many programs running at the startup, low RAM, low processor speed, spyware running as a background application, errors in the Windows registry and the buildup of the garbage files on the hard disk. Scanning your computer with an up-to-dated anti virus and anti spyware program, cleaning and repairing Windows registry, increasing memory, deleting temporary files, deselecting the programs at startup and uninstalling unwanted software applications can solve this problem to a very large extent.

Network Server is not accessible

In a networked environment every computer depends on the server for logon authentication, files access, internet and printing access and sharing server resources. The downtime and the communication failure with the server are very problematic and frustrating for the users. Check both end of the network cable and make sure that the attached RJ-45 connectors are properly plugged into the LAN card and hub/switch. Ping the server’s IP and make sure you get the reply from server. Ensure that your server is on and working fine. A large number of the running applications on the server and simultaneous access to the server from a number of users can slow down the performance and speed of the server. Scan your PC with an up-to-dated antivirus program because certain viruses and spyware are responsible for the communication failure. Replace your LAN card with new one and assign different IP address and try to connect with the server.

Computer locks up or freezes

Missing .dll files, viruses, faulty registry, defective RAM and spyware slows down the performance of the server and it locks up frequently. Scanning PC with the anti virus and anti spyware program, cleaning and repairing registry and increasing RAM can solve this issue.

Computer won’t boot

Faulty power cable, power extension and power supply all contributes to this problem. Checking one by one each of the above components can pinpoint the problematic part. Simply replace that part with new one and your compute is okay.

Computer reboots itself

Defective cooling fan, power supply, RAM, viruses and spyware can cause this to happen.

Memory usage is maximum in computer

Either the memory is less than the recommend memory to run certain applications, swap memory chips with each other, scan your computer for viruses and spyware, increasing the page file and physical memory can overcome this problem.

Browser’s home page has changed itself

This is most likely a spyware problem and scanning computer with an up-to-dated anti spyware program can fix this issue.

Computer’s clock losing time

If you see that your computer’s clock is losing time frequently replace your CMOS battery.

My computer can’t get connected to internet

Check IP address, gateway address, scan your PC for viruses and spyware, check network cables and make sure that server’s or gateway’s firewall application is not blocking http requests from your PC.

Computer making noises

Faulty RAM, VGA, hard disk, Sound card, Processor and other components produce noises. Make sure that each hardware device is properly connected inside the PC and if the problem is still not resolved then replace the faulty hardware component with new one.
