A friend of mine has been having an issue with her desktop computer for a while. What it does is it will randomly shut off (completely shuts the power off) in an instant and does not attempt to restart itself back up. Sometimes this will happen when booting the computer before she can type in her password to log into the computer. Sometimes it will run for hours and hours without issue then randomly shut off. I suggested the power supply. So I changed that the other day to a more powerful one. It ran good for about a day and a half and then tonight randomly shut off once more. My only other ideas is motherboard or cpu. I figure most other issues such as ram, or hard drive or whatever would freeze or shut down the computer but the computer at least would attempt to restart itself on its own. Its windows 10. I can provide more info if needed. Does anyone else have any ideas or suggestions?
