Computer fails to start
Computer fails to start or fails to turn on.
When a computer fails to start there is often no warning, it can be working fine when it was turned off, but then wont turn back on.
There are a number of reasons that a computer wont turn on. Here is a list of possible faults starting with the most simple first.
Is it turned on?
Other people or another reason the computer may actually be turned off, look and see dont take if for granted. check the correct lead is pluged in to the mains as well.
Is the power cable secure?
check both ends of the cable to make sure its firmly in place.
Blown fuse?
If you have a certain type of lead thats used on your computer, typically a kettle lead, try pluging it into something else that has the same fitting, if that works then the fuse and the lead can be found working or not working. if you cant find the same fitting, replace the fuse with a working fuse.
In summer months, the side may be off the computer case, of someone may have been inside the computer, check the cables are attached inside, some motherboards have LED lights on them that will light up if there is power.
Also consider if there has been any thunder storms within a 60 mile radius of your home.
In most cases the PSU ( powersupply) may have been broken and will need to be replaced, on some other cases the motherboard has failed and need replacing. You can find out if its the PDU by taking off all the internal plug and connecting pins 12 and 17 (green and black) on the ATX connector to see if the PSU starts.
Computer turns on but then turns off almost right away.
If you have just built the computer, then you have put it together wrong.
