PC only starts sometimes; won't start on first try

Have you ever experienced this frustrating situation where your Windows computer sometimes starts up when you press the power button, but never the first time? You try again and again and it finally starts. This is a problem that many people have faced. In this article, we will share how to solve this problem.

Why does my Windows computer only boot sometimes?

Here are the reasons behind random startup issues that Windows computers sometimes have:

• Faulty cmos battery: The cmos battery is a small battery that powers the BIOS and stores critical BIOS information needed to boot your PC. If the battery dies or malfunctions, it can cause your computer to act like it's only booting up every second.
• RAM: RAM is one of the most critical components of a PC, it stores the instructions needed for the PC to function properly. Slow or faulty memory can cause problems when your computer starts up.
• Fast Startup Problem: Fast Startup is a feature of Windows that stores some information to enable Windows to start faster. However, this information can sometimes become corrupted, causing your Windows PC to boot only every second.
• Problems with Windows startup files: If the startup configuration data file is corrupted, the computer may not boot – but in my experience it may boot randomly.

Fix PC sometimes only boots up

If your Windows computer has occasional startup problems, try checking that the power cord is well connected, making sure the electrical outlet is working properly, and cleaning the internal fan and radiator. If the problem persists, you may need to reinstall the operating system or check for hardware failure.

Windows 11 fails to boot on first try

1]Disable fast startup

In order to improve the startup speed of Windows PC, the system will store some data for quick startup. However, sometimes this data can cause startup issues. If you encounter this situation, it is recommended to turn off the fast startup function to solve the problem.

• Open Control Panel by searching for it in Windows Search.
• In Control Panel, change the view mode to Large icons.
• After this, open the power options
• Then open the ability to select the power button from the left pane.

• Now, click on the Change settings option that is currently unavailable.

• Finally, uncheck the Fast Startup option and click Save Changes.

2]Use the hardware reset button

Some Lenovo models and devices from other manufacturers are equipped with a small pinhole that can be used to restore the PC or access UEFI firmware settings if the system fails to boot. This button is usually located near a USB port, 3.5 mm jack, or power button.

For more information about the hardware reset button, consult your computer user manual. The function of the hardware reset button is to restore the hardware settings to the default state, which helps solve the problem of the computer starting only every second.

3]Rebuild BCD file

Rebuild the BCD file and see if that helps.

3]Replace memory

Slower, older, or faulty RAM may have problems storing instructions for your PC to function properly. In this case, it is recommended to upgrade your PC’s RAM to a more modern and faster RAM.

If you are operating under the operating system's minimum memory requirements, consider extending the memory size. Check to see if your computer has additional memory slots for replacement or upgrade memory. In this case, you can DIY it according to the manufacturer's instructions. If your PC has soldered memory, please contact a technician.

4]Unplug the CMOS battery plug

A drained or faulty cmos battery will have problems storing BIOS information and powering the BIOS, possibly causing your PC to boot only sporadically. To replace the cmos battery you must open your cabinet.

On a laptop, this process can be complicated. The CMOS battery is usually located near the graphics card slot, and there is usually a plus or separate slot for the CMOS battery. See the manufacturer's website and user manual for detailed instructions on removing and replacing the CMOS battery on your motherboard.

I hope this article helps solve this problem and you can turn on your computer with just one key press.
