Troubleshooting Why Computer Will Not Start or Boot Up:
Common causes of boot up problems include wrongly installed software, defective drivers, failed updates, sudden power outages, and improper system shutdown. Not to mention virus or malware infections, which can entirely disrupt a computer’s boot process due to registry degradation.
Common Causes of Computer Start-Up Issues:
The diagnosis of computer hardware can be very challenging; the goal of this article is not to take the position of a repair professional, but rather to identify the typical issues that may be easy enough for a layperson to solve.
This article also makes the assumption that you have electricity coming from the socket you are plugged into and that all external USB devices, aside from those that are absolutely necessary, including keyboards, mice, monitors, and power cables, have been disconnected. So let’s get started, shall we?
- Examine your cords.
- It is frequently possible to split laptop cords at the power block; check sure all ends are securely fastened to the wall, adapter, and laptop.
- Check that the 3-prong cord for desktop computers is snugly inserted into the back of the computer’s power supply and securely fastened to the wall outlet/surge protector.
- Before carefully scrutinising them, make cautious to unhook from the wall if the cord is frayed or a pet has eaten through it. The cords must be changed if they are damaged. On cords with exposed wire, do not use electric tape. Laptop power cables are much thinner gauge than desktop power cords. If they have been chewed through, the computer may not receive enough power or there could be a fire.
- If a prong is destroyed at the end where it plugs into the laptop, it will not charge or charge in a subpar manner, which is more common with laptops than desktops.
Insertion Points: Jacks for laptop power.
If the cables are perfect but there is no sign of power on the laptop, it’s conceivable that the power jack is malfunctioning. A technician is required for this type of repair. In order to repair or solder in a new jack, the complete laptop frequently needs to be dismantled. It’s a common issue that you might need to hold the power cable in a specific way in order to power the laptop.
Beware; it’s still conceivable that the power adapter is defective and generating a problem that is quite similar. The only way to tell the difference is to check with a volt metre to verify if the voltage indicated on the power adapter—for example, 19v—is actually being output.
A desktop power cord rarely fails at the point of insertion in the rear of the computer, though it is possible if the wire was stressed or jolted in some way. There should be very little flexibility or wiggle in the connection between the power wires and the back of a desktop computer.
There are numerous symptoms of power supply failure; I have a whole post devoted to this failure. Go ahead and read ” How To Fix A Dell Inspiron Laptop That Won’t Boot  ” if you would like.
