Question Error CPU/Mobo Reading Sensor

[kuririkura]

Hi guys,

Sorry newbie here, suddenly my PC takes too long to boot, i check on the BIOS or on the monitoring, all the temperature and fan speed reading are broken,

In the bios CPU shows -0 or -5 C (room temp 32C) and fan speed of 65535 rpm..
In the windows monitoring shows as below


My question is the sensor belong to CPU or motherboard? which part i need to replace?
PS: BIOS update didn't help

CPU i5-4570, MB Asrock H87M Pro 4

Update: on MSI afterburner the CPU temp shows 50-56C

Thanks,
Eka

I also notice that none of your power supply voltages are showing in the BIOS either.
Being that the BIOS update didn't help....I'm suspecting there's a motherboard issue.

shutdown the computer. remove the battery on the motherboard. wait for 1 min and put the battery back. now the bios is reset. boot the pc and go in to bios and see if the sensors works. if not i suggest that you replace the board.
