Turn On and Off Loop

[Ld27980]

I have not used my computer in awhile and since my laptop broke I am trying to use my computer for a few more weeks of college, but every time I plug in the power cable to my pc it turns the pc on by itself then a few seconds within 2 seconds or so it turns off then turns back on. I saw that some people said to reseat the ram and I have tried that and it does not work. I had barely ever used the computer, at most I’ve turn on the computer about 50 times within its 3-4 year purchase span. What are some option for a broke college man.

@Ld27980,

Thank you for posting your query on HP Support Community,

Let's try these steps here: 

Perform a Hard reset on the PC: 

Many startup errors and other problems can be resolved by decreasing the amount of power stored in hardware components. Decreasing stored power is sometimes referred to as a "Hard Reset". Use the following steps to perform a hard reset on a computer:

1. If Windows is open, click Start and then Shutdown.

If Windows is not open and the computer has power, press and hold the power button on the computer until the computer shuts off.

2. With the power off, disconnect the power cord from the back of the computer.

3. With the power off and the power cord disconnected, press the power button on the computer for 5 seconds. The power light indicator on or near the power button might turn on briefly but then go out.

4. Reconnect the power cord and turn on the power.

The hard reset does not work :(. As soon as the power cable isn’t plugged in it automatically turns on by itself and does the loop, I can’t even press the power button to shut it up cuz it turns off by itself. If it’s the power supply is there anyway I can purchase a new one or a similar one.
