If you notice lines and spots on your computer monitor, it means that the pixels on your constantly on monitor have deteriorated due to displaying the same image continuously. These marks are traces of the image that was continuously displayed in the past. If your monitor has reached this point, there is practically no chance of repairing it.

Is the image displayed on your monitor of lower quality than expected? Do you have a high-quality graphics card and monitor, but you still can’t get the image quality your computer should provide? In this case, you should immediately consider the video cable. Check if it’s properly seated in its socket. If everything looks normal, try your computer with a new and high-quality video cable. Your problem is likely to be resolved. Some products (video cables) in the market may be of such low quality that they won’t meet your needs, and you may encounter unexpected issues.

Is the image on your monitor flickering? Are the colors sometimes distorted? There are several factors that can cause this. First, make sure the video cable is securely connected to both the computer and the monitor. If the socket is properly seated, and the cable is of good quality, you have two options left. First, your graphics card may be failing. In this case, remove the graphics card immediately and make sure the fan on it (if present) is spinning freely. If it’s not spinning, replace the fan before using your computer further. If you don’t replace it, the graphics card will suffer damage from excessive heat (solder joint failure). If your graphics card is sound, the second factor may be the monitor itself. To determine this, take your monitor and try it on a friend’s computer. If the problem persists, your monitor is likely faulty. In this case, you should send the monitor to a service center for repair or purchase a new one.

Sometimes, graphics cards can cause unexpected malfunctions. When these cards, which are plugged into slots called PCI slots, fail, they can affect the motherboard and lead to strange problems. Sometimes, motherboards can even be thrown away without realizing it, just because of graphics card failures. Let us briefly explain this situation to you. If your computer freezes a few minutes after connecting the CPU, RAM, and even the computer’s backup hard drive to the motherboard, our advice is to remove the graphics card plugged into the PCI slot and try running the computer without it. Most likely, the problem will be resolved.

Is your computer working perfectly, but you can’t give commands from the keyboard or mouse? In this case, turn your computer off and on. If the problem persists, change the USB input port for your mouse or keyboard. Turn them off and on again. If the problem still persists, try with another keyboard or mouse. If it works with another one, it means your mouse or keyboard is defective.

Does your computer suddenly freeze? Does it shut down suddenly? Immediately unplug the computer’s power cable. Open the case and check if the fan on the CPU is spinning freely. To be even more sure (unless you are an expert on electrical shock, please seek assistance), run the computer with the case open.

Make sure the fan is spinning properly. If the fan is not spinning correctly or making excessive noise, replace it immediately. In the other case, a CPU that is not properly cooled will always exhibit these symptoms. If there is no problem with the fan, your issue is not related to the CPU.

Applying thermal paste to the CPU

CPUs generate a significant amount of heat while operating. A CPU fan is used to dissipate this heat, and thermal paste, a semi-liquid material called thermal paste, is applied between the CPU’s fins and the CPU for heat conduction. We recommend changing this material approximately every two years.

Did you hear a “beep” sound when you turned on your computer? Immediately check whether the RAM is properly seated in its slot. If your problem is not resolved, change the slot where the RAM is installed. If this doesn’t solve your problem either, your computer has a section that counts the RAM amount on the screen during boot. For example, if you see a section like 1956421 kb and the computer completes and continues, your RAM is probably fine. If it doesn’t pass, you will need a new RAM.

Is your computer crashing shortly after installing the operating system? Are you unable to get rid of blue screens no matter how hard you try? Do you want to format the hard drive but can’t do it? If you experience these symptoms, your hard drive may be faulty. Especially if the operating systems crash on their own (assuming it’s not due to a virus), your hard drive may be faulty. If your hard drive is faulty, there is usually not much you can do about it. The best thing you can do is immediately recover your valuable data. Then get rid of that disk without wasting any more time. In the other case, your experience in installing operating systems will increase more than you want.

If your power supply is not “switch mode,” there is no reason for it not to malfunction. The main reason for power supply malfunctions is electronic capacitors in 90% of the cases. A computer power supply that continuously operates under power can fail in a surprisingly short time. According to our experience, a standard power supply fails within an average of 3 years when it operates 8 hours a day.

Signs of power supply failure are as follows: if there is no response when you try to turn on your computer! If your computer does not respond to any command or button when you shut it down properly and normally but does not respond when you try to turn it on, your power supply is defective. What you need to do is to immediately get a new power supply and try it. Generally, this is a problem caused by the continuous exposure of the capacitor to voltage.

Power supplies can sometimes cause strange malfunctions. Your computer may suddenly shut down while passing the BIOS startup page, and then try to turn on again. Sometimes it can work for a day or two. But if your computer opens and closes repeatedly during startup (before the operating system starts), it’s time to replace your power supply. This usually indicates that the capacitors inside the power supply have reached the end of their life cycle.

If your computer’s clock is resetting to an unknown time, it means your BIOS battery has likely run out (viruses can also cause this, although we assume that possibility doesn’t exist). The BIOS battery is responsible for providing continuous power to the time integrator and BIOS chip on your motherboard. If the battery runs out, the time integrator won’t work, causing the date to revert to its default value.

If your computer isn’t responding to anything, even after changing the power source, it’s time to say goodbye to your motherboard. Motherboard failures are very rare, but they can happen at any moment. In such cases, there’s often no way to salvage the motherboard. Seeking professional assistance in these situations will prevent you from making the wrong decision.

Motherboards have physical differences in components based on their brands and models. For example, the cooling system attached to the North Bridge may vary from model to model. The North Bridge is an integrated circuit that controls communication between components like RAM and the CPU. If the fins attached to it don’t adequately cool the North Bridge for any reason, it can lead to mysterious issues such as sudden shutdowns and slowdowns. Diagnosing this problem requires serious expertise, so most of the time, our motherboards end up being discarded.

Above, we’ve provided you with some tips on computer issues. When performing these procedures, be cautious about electrostatic discharge. If you don’t have sufficient knowledge about electricity, we don’t recommend opening your computer case.

8 – Operating System-Related Issues

If your operating system files are damaged, your computer won’t boot. Factors that can damage operating system files include viruses, hardware errors, and improper shutdowns. But when you encounter such a situation (your computer constantly tries to restart itself), you can attempt to repair the operating system. The method for Windows XP is outlined below.

9 – PC Clock Changing on Its Own?

Sometimes, your computer’s clock changes on its own. There are a few possible reasons and solutions for this.

– Your BIOS battery may have run out. When you unplug your computer, a circuit starts using the BIOS battery to keep the time up to date. Generally, if a PC remains unplugged for a long time, the BIOS battery tends to run out. In this case, the solution is quite simple: usually, you can buy a CR2032 battery and install it on your computer’s motherboard.

– The clock circuit on your motherboard may no longer be functioning. This can happen in very old PCs that have been without power for a long time, leading to a depleted BIOS battery. The solution is straightforward: if you require an accurate system time, replace the motherboard. If this computer is supposed to work with the correct time and is part of a local network, a computer with the correct time on the network can perform time synchronization for your PC. The system synchronizes its clock with the correct time on the network every few minutes.
