This girl’s mom came in with her gaming computer & asked me to find out the problem.
It was her SSD drive, it had failed, and was causing the machine to hang & not boot. In fact, they could not even get into the bios.
I sold her a Samsung 970 M.2 & installed it as well as windows.
I then proceeded to update the machine, make some changes to increase the speed of the computer, especially while she gamed, & installed the latest drivers for her chipset & graphics card.
I also updated her bios. I was able to get her the computer back the same day.
