Computer turns itself off! – PC Repair – Computer overheating in Coventry
If you find your computer or laptop is suddenly turning itself off (which could result in loss of work and could cause file corruption) this article is for you.
If there is no obvious reason for it, e.g. there is no blue screen of death (BSoD) message then the problem could be your computer overheating and is a relatively simple one to fix!
Modern computers have protection for overheating built into them. If something goes wrong on your system instead of melting your CPU back into a pile of expensive glass.
The computer will automatically shut down at a temperature that is dangerous to the health of the system. This could be accompanied by a series of beeps from an internal speaker.
Other symptoms to look out for are:
- If you computer fans running louder than usual
- Your laptop fan is always on and very loud.
- Laptops will be hot to the touch – sometimes burning hot!
- Your system will also be running slow.
As well as constantly shutting down on you, running your hardware like this will drastically reduce the life of it and could even result in the solder points on chips being melted, causing a fatal failure of your hardware.
If the system shuts down on you without warning the system will often boot again only to turn off relatively quickly when it again reaches the threshold safety temperature.
This is a good thing (unless you were working on something important!)
Not to worry – you likely just need some computer system cleaning.
Cleaning the system
Cleaning the heatsink and fan can often solve these problems and it is good practice in this situation to re-apply some fresh thermal paste.
This will increase thermal conductivity between the processor and the heatsink (which dissipates the heat from the processor like a radiator, in turn, cooling it down).
This is more likely if the fan has been clogged up and could have burnt itself out.
This is not very expensive and is a relatively simple fix on most machines and will be identified by seeing if the fan is spinning.
Most modern computers will alert you to the failure of a CPU Fan and will be identified when the computer performs it’s PoST (Power on Self Test) checks on start up.
If you are in urgent need of your system but it is suffering from computer overheating you could get away with removing the broken fan and pointing a desk fan directly at the heatsink – this may get you out of a pinch but is certainly not recommended!
What about laptop fans?
On laptop systems the exhaust vent in which the laptop expels it’s hot air out of is a common place for dust and grime to accumulate.
If you have pets such as dogs or cats as a few hairs can give dust something to settle onto instead of just being expelled out of the case. This can fully clog up airflow and cause computer overheating.
You can put your hand over the exhaust vent to feel airflow during high processor usage, if you don’t feel any warm air – you have a computer overheating problem!
Like PC systems, laptop fans can also fail with time or burn out if they are stopped from spinning by the build up of dirt, although a bit more of a pain to get to and source replacement, it is still a relatively easy fix.
How do I clean my computer system?
Any build up of dirt from heatsink fans should be removed by hand and not with a vacuum as the act of moving the particles of dust up the vacuum nozzle could generate static electricity which computer components are very sensitive to!
Once the problem has been identified as computer overheating due to build up of dust and grime other fans should be checked and cleaned.
They will likely be in a bad condition too, some places to check are the video car which often has a heatsink fan and the Power Supply Unit fans which can also get badly clogged with dirt and grime.
