I received my HP Flagship Pro Desktop 2018 computer on July 1st, 2020 and received it around July 7th, 2020. While doing my college work on June 19, 2021, it suddenly shut off without any warning. I went out to Staples to purchase another power cord and it still didn't work. Unfortunately, the return window has expired on Oct. 3, 2020. Now I'm stuck with a computer tower that functioned for only 10.5 months. Is there anything that could be done?
