Recently, I’ve been experiencing a frustrating issue with my computer—it keeps getting stuck in an endless cycle of turning on and off. Every time I attempt to power it up, the computer starts booting and then, within a few seconds, it shuts down and restarts the process all over again. There’s no pattern to it; it just keeps looping through the same cycle without ever fully booting into the operating system. I’ve checked for obvious issues like power supply problems and overheating, but everything seems fine on the surface. I’m at a loss as to why this is happening and it’s becoming a real challenge to work on anything. Any insights into what might be causing this problem would be greatly appreciated.

Your computer might be overheating. Ensure the CPU fan is functioning properly and that the thermal paste on the CPU is appropriately applied. Dust buildup can also lead to overheating, so clean the cooler and heatsink thoroughly. Overheating often triggers automatic shutdowns that create a boot loop.

There could be a hardware connection problem. Double-check that all internal cables and components like RAM and GPU are securely seated. Take particular care with the RAM; try re-seating it by removing and reinserting the modules. Loose connections can often cause boot loops.

One possibility is a faulty power supply unit (PSU). This common hardware issue can lead to unstable power delivery, causing endless reboots. Test the PSU with a multimeter to ensure it maintains a stable voltage. If it fluctuates, consider replacing the PSU to resolve the boot loop.

Software issues, such as corrupted system files, can cause this problem. Use installation media to attempt a repair of the operating system. If you suspect malware, employ a bootable antivirus tool to scan for infections that might be disrupting the boot process. In extreme cases, a system restore or factory reset may be necessary.

If you recently added new hardware, the power supply might not meet the system’s increased demand. Consider upgrading to a higher wattage PSU. Additionally, external peripherals like USB drives or printers could interfere with the boot process; disconnect these devices and attempt to restart the computer.

The problem could lie with the BIOS settings. Try resetting the BIOS to default configurations by either using a reset button on the motherboard or removing the CMOS battery for a few minutes. Misconfigured BIOS settings often result in boot loops, and a reset can restore system stability.

Sometimes, faulty RAM or incompatible memory modules might be the cause. Run a memory diagnostic test to check for errors. If you have multiple RAM sticks, test them individually by removing all but one. This isolation test can help identify a problematic module.

Outdated or incompatible drivers, especially for critical components like the graphics card, can trigger restart loops. Boot into safe mode or use a bootable disk to update or reinstall the necessary drivers. Ensuring compatibility and up-to-date drivers can prevent such issues from occurring.
