Hi All

I've recently made a thread here, this issue has been resovled:

But now another issue has risen: I get the error 'CPU over temprature error' when I boot my computer after it being off for over 10+ hours. The computer loads windows before it crashes and restarts. once it restarts the error appears.

Then I go into BIOS where the temprature appears high (70+ and climbing), this is where I quickly save changes and exit BIOS without really making any changes. Then computer restarts and I enter BIOS again by hitting DEL key, this time temps are dropping and stabalise at 32-36 degrees.

Then I exit BIOS and this time let it boot windows, then the computer runs fine. I check CPU temprature and its stable. I can use the computer normally for hours without issues. I can even restart it, I can also put it to sleep and reuse it after an hour. I also switched it off, waited for 30 mins and switched it back on and I didn't get 'CPU over temprature error'.

However comes the next day, and the first boot up comes up with the same crash and error message.

All fans seem to be working, radiator, the pump LED lights up (although I dont know if the pump fan is working on the first boot)

Whatever the issue is, it seems like I always need to enter into BIOS, do nothing, save changes and exit then it works.

Does anyone know what's causing the issue? could it be something wroing with the motherboard BIOS and pump fan?
