Why won't my computer turn on?

Have you checked if the power cable is plugged in and the switch next to the power cable port is switched to on?

RAM has nothing to do with this btw.

Make sure your computer is plugged into a functioning outlet. If no power is going to the desktop, it cannot function. This PC has no battery. If there is still no response, you may want to try accessing more RAM. Other solutions to this issue can be found on the troubleshooting page.

After 6checking the power cord is plugged into a working outlet and securely seated in the back of the PC at least in our one time case pressing. Control- alt-delete seems to have enabled it to be turned on when the power button on the keyboard was not responding.
