Introduction
A computer that’s not powering on can be a frustrating experience, but there are a few things you can try to troubleshoot the problem and get your computer back up and running.
Check the Power Source
First of all you should check for the power source. Make sure the computer is plugged into an outlet and that the power switch is turned on. If you’re using a power strip, try plugging the computer directly into the wall outlet. If the computer still doesn’t turn on, try using a different outlet.
Check the Cables
Make sure all of the cables are securely plugged into the computer. This includes the power cable, the monitor cable, and any other cables that are connected to the computer. If any of the cables are loose, tighten them or try replacing them.
Reset the Power Supply
If the computer is still not turning on, you can try resetting the power supply. To do this, unplug the computer from the outlet and wait for 30 seconds. Then, plug the computer back in and press the power button.
Clear the CMOS
The CMOS (Complementary Metal-Oxide-Semiconductor) is a chip on the motherboard that stores the computer’s settings. Sometimes, the CMOS can become corrupted and prevent the computer from turning on. To clear the CMOS, you will need to open the computer case and find the CMOS battery. Remove the CMOS battery and check for the voltage if you have multi meter and then put it back after 30 seconds.
Reset RAM Modules
Turn off the computer and disconnect the power.
Reset the RAM modules. Take them out and then firmly put them back in place
Check the Hardware
If the computer still doesn’t turn on, there may be a problem with the hardware. This could be a problem with the motherboard, the CPU, the RAM, or another component. If you are not comfortable troubleshooting hardware problems, you will need to take your computer to a repair shop. And if you are located in India Gurugram you can visit or contact the company

Listen for Beep Codes
If the computer is plugged in and turned on but nothing happens, listen for any beep codes coming from the computer. Beep codes are a series of sounds that the computer’s BIOS (Basic Input/Output System) emits to indicate a hardware problem.
The meaning of beep codes varies depending on the computer manufacturer, so you will need to consult your computer’s manual to determine the meaning of any beep codes that you hear.
Beep codes are a series of audible signals produced by a computer during the Power On Self Test (POST) process. These codes help indicate the status of the computer’s hardware components. The exact meaning of beep codes can vary depending on the computer’s BIOS (Basic Input/Output System) or UEFI (Unified Extensible Firmware Interface). Different manufacturers may use different beep codes, so it’s important to refer to your computer or motherboard’s documentation for accurate information. However, here are some general guidelines:
- No Beep: If you don’t hear any beeps at all, it could indicate a power supply, motherboard, or peripheral issue.
- One Short Beep: This is usually an indication that everything is okay and the computer is booting normally. It’s often referred to as the “POST beep.”
- One Long Beep: This typically indicates a memory (RAM) error. It could mean that there is a problem with the RAM or that it’s not seated properly.
- Two or Three Short Beeps: These beeps usually indicate a problem with the RAM. It could be a memory error or that the RAM is not properly installed.
- One Long Beep, Two or Three Short Beeps: This often indicates a video-related issue, such as a problem with the graphics card or the display.
- Continuous Beeping: This can indicate a power supply or motherboard problem. It’s important to check the documentation for your specific system to interpret continuous beep codes accurately.
- Beeping with a Black Screen: If you hear beeping but the screen remains black, it may indicate a video or graphics card issue.
- Beeping After Adding New Hardware: If you’ve recently added or replaced hardware and you hear beeping, it might indicate a compatibility issue or that the new hardware is not properly installed.
Remember, the specific meaning of beep codes can vary, so always refer to your computer or motherboard’s documentation for the most accurate information. If you’re unable to determine the cause of the beep codes, you may need to contact the computer or motherboard manufacturer for assistance.
Check the Monitor
If you are hearing beep codes or seeing any lights on the computer, but the monitor is not displaying anything, the problem may be with the monitor itself. Try connecting the monitor into a different computer to check if it works.
If the monitor works with another computer, the problem may be with the video card in the computer that you are troubleshooting.
Reseat Internal Components
If the computer is still not turning on, you may need to reseat some of the internal components, such as the RAM, CPU, and video card. This involves removing the components from their slots and then reinserting them.
Be careful when reseating internal components, as you can damage them if you are not careful. If you are not comfortable doing this yourself, you may want to take the computer to a computer repair shop.
Preventative Measures
Here are a few things you can do to prevent your computer from not turning on in the future:
- Use a surge protector to protect your computer from power surges.
- Make sure your computer is properly ventilated.
- Keep your computer clean and free of dust.
- Keep the computer away from moisture
- Back up your computer regularly.
By following these tips, you can help keep your computer running smoothly and avoid the frustration of a computer that won’t turn on.
