Recently acquired Dell Inspiron N301Z, with the information that it needed a new OS. I downloaded a tool to import Windows 7 to a USB and followed the instructions to boot a computer from a new OS, but when I turned on the computer I found that it simply had a black screen, no logo/message, which is supposed to appear in order to use a key combination to access the BIOS to my knowledge. Have tried various key combinations, including Esc, Del, and most of the function keys without any success. Additionally, the power seems to randomly either stay on or shut off about 10 seconds after I push it. I was informed that this was not an issue with the display, which is why I have posted in here instead. Any help would be appreciated greatly.
To my knowledge the laptop was bought as-is, so the specifications are probably accurate to this: https://www.manualslib.com/manual/254622/Dell-Inspiron-N301z.html?page=78#manual
I have also tried installing a BIOS driver from the official website with similar results.
