    CPU heating

    Greetings,

    there's a problem with my PC in the last 3-4 weeks. The system started to heat up over a night. I've looked at the BIOS and the CPU's temperature goes up from 38 to 70 in 2 mins - and there's nothing running JUST THE BIOS...

    I know that's a hardware issue --> motherboard or CPU? Can be something else?

    Thank you in advance.

    First check for dust on the heatsink and try applying new heatsink grease on the CPU.

    It might also depend on the CPU you have. I have a socket T Pentium 4 that runs about 70 degrees and it seems like there is nothing I can do about it other than buying a $75 heatsink to cool it down a little bit. I'd rather just run it hot. I've been doing this for quite some time now and no problems yet...

    It could also be faulty fans.

    Use air blower to clean your system. and then check the temp. if still having problem unplug the heatsink of processor and apply a new grease.

    It could be faulty motherboard readings, usually when your temperature sensors go wackko it is unlikely to be the CPU heating to the point of melting.

    Open your case and check for dust, dust can decrease air flow and therefore heat up your computer.

    Take out the heatsink and fan, clean both.. apply a new thermal paste and that should do it.
