6  Ways to Fix Random Computer Restart Issue

Fix 1: Resolve overheating problems

Overheating can cause unexpected restarts. While physically feeling if a device is hot to the touch is one way to detect overheating, it’s also important to check its temperature using other methods.

How Do I know if my Computer Temperature:

Select a free CPU temperature monitoring program like Core Temp for Windows. Mac users can consider “System Monitor”, and Linux users can explore “lm-sensors” or “Power Gadget”.

• Download the program and Open the program
• Open the downloaded .exe file, from your downloads. your computer may prompt you to grant permission for the app to make changes; opt for “Yes” here.
• Once the Core Temp Setup Wizard appears, click “Next” on the following screens, pausing briefly to adjust your download location if necessary.
• You’ll encounter a screen with checkboxes, none of which require checking. While many will uncheck the “Build your kingdom with Goodgame Empire” box, the other two pre-checked boxes are based on personal preference.
• When installing Core Temp on Windows, you can keep the “Create a desktop shortcut” box ticked for quick program access or leave.
• Click “Install” on the subsequent screen to complete the installation, and then click “Next” once more. Finally, hitting “Finish” will launch the Core Temp program along with a Readme.txt file containing instructions.
• In the Core Temp program interface, you’ll find your CPU’s current temperatures under the “Processor #0: Temperature Readings” section. Depending on your processor, you may see readings for each core or just the primary one.

How much should be CPU Temperature? A normal CPU temperature depends on the specific CPU model and the workload it’s under. However, here’s a general guideline: ● Idle: Ideally, your CPU temperature should be around 35-45°C (95-113°F) at idle, when your computer isn’t performing any demanding tasks. ● Load: Under moderate load from everyday tasks like web browsing or office work, the temperature can range from 45-65°C (113-149°F). ● Heavy Load: When running demanding applications or games, the CPU temperature can reach 70-80°C (158-176°F). This is still considered acceptable, but close to the upper limit.

Here are the steps to solve overheating issues:-

I. Improve Airflow and Ventilation

• Proper Placement (Laptops and Desktops). Find a clean, hard, flat surface. Avoid carpets, beds, or uneven surfaces.
• Locate the air vents on your computer (usually on the sides, bottom, or back). Make sure nothing is blocking them, like papers, books, or your body heat (for laptops).

2. Cleaning Dust Buildup (Desktops only)

Warning: Opening your computer case can void the warranty. If uncomfortable, seek professional help.

• Completely turn off your computer and unplug it from the power outlet.
• Consult your computer’s manual for specific instructions on opening the case.
• Use compressed air (available at electronics stores) to carefully blow out dust from vents, fans, and the heatsink (the metal plate on the CPU).
  • Short bursts: Use short bursts of air to avoid spinning the fans too quickly or dislodging components.
  • Hold the fan blades: While spraying, gently hold the fan blades to prevent them from spinning.
• Close the case securely according to the manual.

3. Check Fans (Laptops and Desktops)

• Power on your computer.
• Pay attention to the sound of the fans. Are they running smoothly, or is there any grinding noise?
• Carefully look at the fans through the vents or by opening the case (desktops). Are they spinning freely, or are they clogged with dust or debris?
• If a fan isn’t working or seems damaged, consider replacing it with a compatible model. Refer to your computer’s manual or manufacturer’s website for replacement instructions.

II. Software Adjustments

1. Close Unnecessary Programs

• Press the Ctrl + Shift + Esc keys simultaneously to open Task Manager.
• Look at the CPU, Memory, Disk, and Network usage columns. Close any programs with high usage that you’re not actively using.
• Click on the “Processes” tab. Here, you can end unnecessary background processes that might be consuming resources.

2. Power Management Settings

• Search for “Power Options” in the Windows search bar.
• Select a power plan that prioritizes power savings, such as “Balanced” or “Power saver”. This reduces power consumption and heat generation.

3. Adjust Graphics Settings (if applicable)

• If you have a dedicated graphics card (GPU), access its control panel software (like Nvidia Control Panel or AMD Radeon Settings).
• Locate options related to resolution, texture quality, and other graphical settings. Adjust these settings to a lower level to reduce the workload on your GPU.

III. Hardware Solutions (For advanced users)

1. Thermal Paste Replacement (Desktops only)

Warning: This process requires technical expertise and may void your warranty. Only attempt this if comfortable.

• Research the specific thermal paste compatible with your CPU and heatsink. You’ll also need tools like screwdrivers and cleaning supplies.
• Following your computer’s manual, carefully disassemble the heatsink and CPU cooler.
• Use rubbing alcohol and lint-free cloths to remove the old thermal paste from the CPU and heatsink surface
• Apply a small, pea-sized amount of new thermal paste to the center of the CPU.
• Carefully reattach the heatsink and CPU cooler, following the manual’s instructions.

Fix 2: Fixing hardware issues

Random restarts on your computer can be frustrating, especially if they happen during important tasks. While software issues can sometimes be the culprit, hardware problems are a strong possibility too. Here’s how to troubleshoot hardware issues that might be causing random restarts:

1. Examine Memory (RAM)

Faulty RAM modules can lead to system instability and crashes. Here’s how to check RAM:

Windows Memory Diagnostic Tool: This built-in tool can scan for RAM errors. Search for “Memory Diagnostic” in the Windows search bar and follow the on-screen instructions to run a scan.

Note:- If the tests identify RAM errors, replacing the faulty RAM module(s) is necessary.

2. Inspect Storage Drives

Hard drive or Solid State Drive (SSD) failures can also cause crashes. You can use software tools like Crystal Disk Info to check the health of your storage drives. Consider data backup and replacing the failing drive if necessary.

3. Verify Power Supply Unit (PSU)

A failing PSU can cause random shutdowns and restarts. However, diagnosing PSU issues can be tricky. If other troubleshooting steps fail, and your computer seems to be power-starved (random shutdowns, flickering lights), consider consulting a technician for PSU testing or replacement.

4. Consider Other Hardware

In rare cases, other hardware components like the graphics card or motherboard could be failing, leading to restarts. If none of the above solutions work, and you’re comfortable troubleshooting further, research online about troubleshooting steps specific to your computer model and components (advanced users).  It might also be helpful to consult a computer technician for professional diagnosis and repair.

Important Note: Opening your computer case to access components like RAM or storage drives can void your warranty.  If uncomfortable performing these troubleshooting steps yourself, seek help from a qualified technician.
