off and turns itself on. I've tried almost everything.

I have even reassemble the system from scratch of the motherboard jus
to make sure everything has been seater properly. It might eve
restart just before the windows logo loading screen from POST

Sounds like a classic case of an overheating processor combined with a bios
that is configured to power the system up if AC is present....

Hi
Thank you for that response
What do you recommend me doing?
The computer is in a living room with no air conditioner present. I'
living in a tropical country with about 30 degrees celcius

Please let me know your recommendations, what should I buy, add o
minus from the system

Thank you in advance

That should still be OK. First, check your fans. The CPU
fan may have stopped. Second, check your airvents. They can
become clogged with dust/fibers. Finally, make sure your
PC gets fresh air and has clear exhaust paths. No carpet
blocking low intake ports. No cabinets!

Also make sure the heatsink has good contact with the CPU and while
you are at it, remove old thermal grease and/or conductive pad and
apply some fresh grease.

Try to run it with case cover off - should help if it becomes marginal
only during Summer time.

Yup - on a Dell I looked at it was bulging Nichicon capacitors.
