Inspiron 24-5459

​I have an Inspiron 24 5459 desktop and it will turn on sometimes but not always. It would shut down for no reason or restart. if you even moved the power chord just a smidge it will turn off. i used to have to turn the power cable back and forth and spam the power button until my mouse lit up but it wont even turn on anymore. The first time it happened i turned it back on and it stayed on for about 30-40 mins so i bought a new power chord and it didn't quite fit but it would still turn on. also the copper "stick" in the middle of the power connector on the computer is a bit bent.​

​help.​
