With apologies on repeating this subject because earlier today posted that the original posting was "Solved" so it seems that now I am unable to get back into it and amend the fact that it didn't work after all and so I see I now have to repost this:-
ORIGINAL POST:- I have had this HP Desktop i7PC since August 2017 but on 'Boot Up' it has recently started producing a short buzzing sound and a 'Blue Box' stating that there is a problem with the CPU fan with a Code of 90B. I have found that it seems to momentarily stick before starting for barely 2 seconds then the fan bursts into life with a sudden jerk after which it runs smoothly keeping the temperature well within the parameters.
I have checked it out and made sure that it is all completely clean, connected and running free, although there is a small end to end (in & out) movement on the shaft of the fan motor. So I suspect that in my case the fan requires replacing. But where EXACTLY could I get one? It looks simple enough to replace i.e. 4 small screws and a connector. Unless of course anyone tells me its not that easy, in which case its off to the local repairer.
But I have noticed that this problem does appear many times one way or another on the forum for various HP machines with no actual pointers as to where to obtain a replacement fan for my particular machine. So I am a little concerned which way to deal with this problem. Any help would be greatly appreciated folks.
As such "Echo_Lake" very kindly offered some checks to try and I went through them. Firstly none of the ideas resolved the problem and No Bios update was offered. But strangely today a 'Notification' appeared on the "HP Support Assistant" and when I checked it offered an Update which was a 'BIOS UPDATE'.
I duly downloaded it and after checking 3 or 4 times that it would now Boot up successfully with the aforementioned problem gone. I posted the original subject as 'Resolved'. However turning on the PC later on today I found that this was in fact not the case - The Blue Screen Warning (Fan F-90) was STILL there.
So I am back at the start again. If anyone can assist please. All that HP has said is to take it into PC World/Curry's for repair. No offerings of where to purchase a New Replacement (obviously faulty manufactured) Fan which would be very simple to pop in myself.
Solved! Go to Solution.
