So, a few months ago I started getting the 90b fan error on my pc. When I took off the side panel (warranty ran out) I could see on startup that the cpu fan would hesitate to start running. I would hit the power button on the pc and the fan would nudge a few times before it would start spinning. BUT, by this point the error has already popped up on the screen and I usually let it shut down and try again. Usually after about 5 tries or so it works normally. I saw where this topic had been posted before and the way to resolve it was to open the case, write down the information on the fan, and purchase a new fan. Except my fan doesn't have anything written on it. I need options to resolve this as it is my work pc. Thank you.
