Is your computer refusing to turn on after giving no indication that anything was wrong with it previously? It may be possible to bring your computer back from the dead because it’s not dead to begin with!
Read on for our top computer revival tips – you may find that the problem is simple and, even better, easy to solve.
1. Surge Protector
Before you even begin diagnosing your computer, perhaps the problem is from an outside source. Even if your computer is plugged into a surge protector or uninterruptible power supply (UPS), it may not be getting power. This is because along with being plugged into the wall, the surge protector needs to be turned on.
The on/off switches of surge protectors can easily be tripped by pets, children, or your foot. Lightning storms and power surges can also disrupt power – in those cases, some surge protectors have reset switches that need to be pushed.
If your computer still won’t turn on while plugged into a surge protector that’s turned on, try plugging it in directly to the wall. If it works after this, you’ll know that it’s not your computer that’s the issue.
If your CPU’s heat is rising too quickly, your PC will either not turn on, or turn on for only a few seconds before turning off again. It does this in order to protect the processor from frying.
This may mean the thermal paste between your CPU and heat sink has dried out. Replacing it is simple. Dampen a lint-free cloth or coffee filter and wipe the old paste from the CPU and heat sink. Then, add a pea-sized amount to the CPU and reattach it to the heat sink.
The thermal paste may need to be replaced every three to five years.
3. Check the Battery
If you’re using a laptop or tablet, you can check if the battery is the main issue by running them through AC power only. If your computer turns on with only AC power, this is an indication that the issue resides with your battery. The simple resolution is to replace it as soon as you can – but until then, you can power it solely through AC power without any harm to your device.
4. AC Adapter
Another common reason why tablets and laptops won’t turn on is a bad AC adapter. Even if you don’t regularly use the cable, a failed adapter won’t be able to send an adequate amount of power to your device’s battery.
5. CMOS Battery
A bad CMOS battery is a common problem from computers that won’t turn on, especially if your computer is a few years old or has been off and unused for a long amount of time. New CMOS batteries only cost an average of $10, and they can be replaced easily.
When you open your computer case, the CMOS battery can be found on the motherboard. For most computers, the model of your battery is a CR2032. However, the best way to purchase the right one is to remove the battery from the motherboard and then take it to a store to find the exact one you’ll need.
6. Power Button
You may just have a defective power button if your computer still refuses to turn on. Testing it requires you to unplug the power switch from your motherboard. After you do this, take a flat head screwdriver and touch it against the pins the power switch was connected to for one to two seconds.
If your device turns on after you do this, then you’ll know that the power button is the cause of the issue.
7. Safe Mode
Instead of a hardware problem, there may be an issue with the software. In order to see if this is the issue, you’ll need to boot your computer in safe mode. Reboot your computer and press F8 as it does – this will start it up in safe mode.
Uninstall any software or driver that you’ve recently installed. If this doesn’t fix the issue, enter BIOS to set the FSB and vCore down to stock levels in case you’ve overclocked.
8. Check Components
Make sure that all of the components of your computer are connected properly by removing and then reinstalling these components after a couple of minutes. These components are:
- Memory card
- Graphics card
- Wires attached to CPU
9. Replace the Motherboard
If you’ve tested every other possibility, then the problem is most likely with your motherboard. However, unlike CMOS batteries or thermal paste, replacing your motherboard isn’t an easy or affordable task.
If you believe this is the case, it’s recommended to take your device to a professional. They can determine if the motherboard really is the cause of the problem before you do any costly upgrades
Computer Revival Is Possible
Unless your computer has been experiencing issues that have been ongoing, if your computer stops turning on or working properly suddenly, the issue is most likely simple to solve.
With patience and trial and error, you can isolate the cause of the problem and solve it before considering getting a new motherboard or even a new computer. However, sometimes you’ll need the help of a professional.
