Solved why does my computer keep shutting down

Hi!
I have been having some trouble with my computer and need some help to understand why.
I had been away for a week and then no internet access for 2 weeks. We just got internet last night and my computer was working fine but when I went on it this morning it started shutting down for no reason (in my mind).
This had happened before I went on holiday. It gives no warning and my computer turns off in a blink of an eye. It has a black screen and sometimes it will try to load up automatically but then shuts off again. It will keep doing this till I shut it off myself.
In a couple of minutes I turn it on again and it works fine for another couple of minutes before shutting off and repeating the same process.
I would love some help for this as I am really confused. Is it better to just buy a new computer?

✔ Best Answer
A number of possibilities.

A faulty power supply
Overheating
Some other hardware fault.

You make no mention of the Blue Screen of Death (BSOD) which suggest to me that you have automatic reboot enabled.

You need to go into Control Panel > System > Advanced > System and Recovery Setting and make sure that automatic restart is un-ticked.

Reboot and next time it fails you should get a screen with lots of information on it. This will give you a clue to the problem. Report back what you find and more help with be forthcoming.

If it still restarts without the BSOD then the problem almost certainly lies with the power supply. The only way to check if it is the power supply is to substitute it with a known good one.

I'm leaning towards overheating as StuartS has suggested.

If you are comfortable with it, take the side off the PC. Hopefully it's a desktop. And have a look at the fan sitting on the motherboard. This is the heat sink fan which cools the CPU.

It will be clearly obvious if there is a build up of dust sitting beneath it.

'Is it better to just buy a new computer?'That is hard to answer because we have no idea what brand or make the PC plus model number is or even if it's a laptop

Hi!
Thanks to all who replied to my plea for help.
I have fixed the problem with the help of StuartS but all the replies were really helpful and I'm really grateful.
I have discovered that the computer is overheating due to a broken fin from the fan. I have a temporary solution of a cooling board.
Thanks again so much! :D
