So I’ve had this pc for almost a year now and it just started not being able to turn on. My PSU has a switch in the back to change the amount of power I think(im not very savvy with computers) so i used to change it to the lower setting and let it warm up then switch to the regular one and it would start up just fine. It still turns on with the lower setting but now it when i switch it just turns off.

When I try turning it on only with the regular setting the lights flash and the fans start for a second then stop. Any opinions for a fix would be appreciated
