Sounds like your power supply just failed. Unplug the power cord, open the case, and look for a metal box inside the case right where the power wire plugs in. Remove the box...usually four screws hold it to the case, remove all of the wires...marking each one and the motherboard so you'll be able to connect the new power supply wires. Most computer stores will have a suitable replacement. Easy replacement if you mark the wires/connections during removal. Just be sure to work with the power plug removed.
Testimonial: "that was exactly what my son said. thank you. can't find an exact replacement in my area. My son said it could also be my motherboard, also no repla"
You could have a virus or infection. Try downloading and installing MalwareBytes and run a Quick Scan. Go to www.google.com and in the search box type:
"Download cnet Malwarebytes" (without the quotes). Download and
install malwarebytes from the sites download.cnet/malwarebytes. When the
site opens up click on the Green Download button on the left. Do not
click the Red Download button, that's junk. When it finishes installing the Gui
Interface will open up with an offer to Accept a Trial Version or
Decline. CLICK DECLINE you want the totally free version. Run a
QUICK SCAN. As it scans, if it finds infections the number will be in
red. When it finishes scanning, click SHOW RESULTS. A notepad text
document will open up showing you the results. You can close the text
document and go back to the Gui Interface where you will click REMOVE SELECTED
RESULTS. The objects will already be selected for you. When it
finishes removing the objects click ok and it will sometimes reboot your
machine.
