In this article, Mytour will guide you through some methods to fix the problem of continuous computer restarts without displaying the BIOS screen.
Identifying the Issue
Discover the telltale signs of a computer continuously rebooting without displaying the BIOS screen:
- The computer operated normally prior to the incessant rebooting issue.
- Attempting to restart will result in the computer powering on and off within 2 - 5 seconds.
- No BIOS startup beep is heard.
- Failure to display the BIOS screen.
- Key functions like F2/ Esc/ Del for BIOS setup/BOOT are unresponsive.
- Recent RAM upgrades have been made to the computer.
- The computer is stuck in a continuous reboot loop.
Rectifying the issue of a computer continuously rebooting without displaying the BIOS screen
Below, Mytour will guide you through various methods to rectify the issue of a computer continuously rebooting without displaying the BIOS screen.
RAM Slot or Faulty RAM is the main culprit causing the continuous restarting of the computer. Follow the steps below to troubleshoot the issue:
Step 1: Remove all RAM sticks from your computer and then restart the computer.
Step 2: Try inserting a RAM stick into different RAM slots and restart the computer.
Step 3: Repeat the same steps with other RAM sticks.
Step 4: Try inserting different new RAM sticks to check if the RAM or RAM slots are faulty.
If the issue persists, it indicates that the culprit causing the issue is either the RAM or the RAM slots on your computer.
Option 4: Removing GPU - Graphics Card
If the aforementioned methods prove ineffective, try removing the graphics card from the RAM slot, then reboot your system. If there's an empty PCIe slot, attempt placing the GPU card into the slot and rebooting the system to check if the error persists.
Usually, the GPU rarely causes continuous system reboots, but that doesn't mean it's impossible.
Method 5: Clean the Dust on the Motherboard
In some cases, cleaning your computer and removing dust from the motherboard can also fix the issue of continuous computer restarts without displaying the BIOS screen. Dust accumulation might be affecting the components on the motherboard and causing the continuous restart problem.
Note to use computer cleaning tools instead of blowing dust with your mouth, as saliva could permanently damage the motherboard.
Method 6: Remove the CPU, and apply new Thermal Grease paste
After prolonged use, the thermal paste on the CPU can dry out, making it difficult to regulate the processor's temperature even when using the best CPU cooler.
Carefully remove the CPU cooler fan and processor from the motherboard. Then, use a soft dry cotton cloth to wipe off the old thermal paste from the CPU as well as the CPU contact surface, apply a new layer of thermal paste, reassemble the CPU cooler, and finally, reboot your computer to check if the error persists.
Method 7: Try different SMPS switching power supplies
SMPS or switching power supplies could also be the cause of continuous computer restarts. Try using different SMPS switching power supplies to see if the error persists. If the error is resolved, it indicates that the culprit causing the error is your SMPS power supply. To fix the error, the only solution is to purchase a new SMPS switching power supply.
8. Check the CPU Socket on the motherboard
Carefully inspect the CPU socket on the motherboard for any bent or damaged pins. Bent CPU pins may be fixable, but if they're damaged, it's considered a complete failure.
Fix any bent pins, then carefully reconnect the processor and restart your system to see if the error persists.
Method 9: Remove HDD / SSD / DVD-RW / DVD drives
Remove the hard drive and other unnecessary peripherals connected to the computer, then restart the computer to troubleshoot the issue.
Method 10: Test the motherboard outside the computer case
Remove the motherboard from the computer case and place it on a non-conductive surface, then attempt to restart your computer with only the CPU and check if the error persists.
This article by Mytour just guided you on how to fix the issue of continuous computer or laptop restarts without displaying the BIOS screen. If you've tried all the methods above but to no avail, the final solution for you is to take it to reputable repair and warranty centers for assistance.
