Hello, my computer keeps turning off by itself.
I thought it was because of a power supply so i bought a new one and installed it.
but it keeps doing the same thing.
sometimes it allows me to enter windows, but then shortly after it turns off again.

i am guessing bad motherboard, but to put it to a test, run memtest to see if you have any errors, if you do, see if you can up your voltage a little and try again, if you still have errors, try another set of memory and run memtest again, if you still have errors - I would say 99% certainty it is your MB, if the new memory has no errors, it is your memory - you can even do test with 1 stick at a time in all the slots, hardly ever do both sticks fail at same time.

Overheating computers tend to turn themselves off to prevent further damage. What are each of your component's temperatures?

It could also be a faulty motherboard. You can try to boot it up with minimal configuration. Psu, mobo, cpu, 1 stick of ram, and hard drive. If it shuts off, take 1 component out at a time starting with the hard drive.

Lastly, try to swap out good parts into your computer to see if it will shut off. You can confirm which parts work correctly this way.

Posting your full system specs (including PSU brand and model, not just wattage) would be very helpful.
