Question Weird laptop issue (won't turn on)

[EchnoRom]

My laptop has an issue where it will not turn on, plugged in, or not. To get it to turn on, I have to wait one week or so without using it, and then plug it in and turn it on. Once on, it lasts for about five minutes before it switches off and will not turn on again (for another week or so) What is causing this and how can I fix it?

Things I've tried but did not fix:
Replacing the battery
Trying a different charger/power adapter

Any ideas? I've got no warranty on this thing so If I can't fix it it's headed to the scrap heap.

It's a dell Inspiron of some kind- looks like this: https://gyazo.com/6e9f2c17ddd9b50cbcefcccc4a506058

Thanks!

Try unplugging it and then holding down the power button next time it turns on and then shuts off. But try it right away and then see if it will restart again immediately.

It sounds like an over heating issue. Open the bottom of it up and make sure the fans are turning on the cpu after you boot it
