New PC keeps switching off

[Skyedriver]

Just before I go back to the shop to chat to the guy, son's new PC has a small prob.
Press button to switch on, it starts up, gets to the Homepage with his desktop icons on and then it switches off. This may happen once or maybe three times before it actually stays on.
Dodgy switch or problem with W10 do you think?
Thanks

Power supply problem perhaps so going into protection mode?

[markiii]

laptop?

Could be the power switch holding down or power supply issue not being able to cope with CPU load whilst booting windows.

usually either power or thermal issues

Plus reseat the memory card.

Is it shutting off suddenly or powering down.
If it is the latter it might be running a load of updates that need reboots.

It's a tower PC not a lap top.
240GB SSD
1TB HHD
8GB RAM
gets to homepage then switches off and needs to be restarted manually.
Can happen 3 or 4 times before it stays on.

Take it back.

[Who me ?]

Try installing SPEEDFAN and check temps http://www.almico.com/speedfan.php

I had a similar symptoms following a computer upgrade. It turned out to be the PSU.

I suggest taking it back. It appears to be faulty.

Been in today, but couldn't drop it off as going elsewhere before. It's going back tomorrow.

Dropped it off, it is believed that there has been a bad batch of power units....
Will keep you informed

Power supply unit faulty. Apparently there has been a faulty batch supplied.
Interestingly, there must have been a "dead" fan too or at least a dead power supply to a fan. As when switching on, my son immediately noticed the extra fan noise.
