Solved Fans running full speed

[rsinbad]

Hi
Switched on the pc this morning Fans running at full speed ... switched off and restarted two or three times with the same effect. Looking inside the pc the cpu was clean and virtually free of dust and connections were fine.I started the pc again and ran pc wizard to check temperatures (quad core ) all threse were fine, however noticed that one of the Hardware monitors was reading 90 c.(TMPIN1).

The pc is not very old
Hp Pavillion HPE h8-1170uk desktop pc
IPISB_CH2 (chicargo) mother board
16 G memory

Thinking that the pc is still under warrenty thought I wouldn't start taking things to bits, so put the side on andthought I'd try it again ... I haven't really done anything , but it started fine and several reboots have been ok.

The only thing I did different was to disconnect the power lead and press the start button a couple of times ( discharge the caps).

Any ideas ?

Yes, one idea. Sometimes a device in the system does not "enumerate" correctly during the BIOS boot. Put simply, the BIOS "names" each connected device and keeps a list (checksum). When you boot the connected devices are checked against the list. If one of the devices on the list does not respond correctly then the system has to try and resolve the discrepancy. The BIOS will not completely release the system to the OS until it has done so. If it gets stuck in a loop then it will search forever.

I believe what you accomplished was some sort of "soft" ClearCMOS. By cutting power and draining the caps you allowed the system to refresh. It found all it's parts and you are good to go.

This type of behavior does not need to indicate any failing parts. It can happen simply due to a minor power fluctuation or data logjam. One time does not make a pattern. Keep your eye on it and if it happens more often then you may need to look into it further.

Hi,

I would also suggest you to do Flee Power. Remove the battery and charger/ac adapter/power cord from your HP notebook, press and hold the power button for 20 seconds to discharge any residual current inside the laptop. You can even try doing BIOS default.

Thanks for you feedback, sounds logical what you are saying so far its started fine no problems. Don't know why I Drained the caps ,but fortunately that seemed to restore the bios.

Hi,
My apologies, as this is a desktop remove any 3rd party peripherals and power cord, press and hold the power button for 20 seconds to discharge any residual current inside the desktop.
