CPU overheat before Windows can start

[BigBill]

Hello there,

For the past 2 years, my CPU (Intel core 2 quad Q6600) have been idling at about 83 degrees. Recently I decided to fix the problem by replacing what left of the thermal paste.

After cleaning, removing and adding new thermal paste to the stock cooler, I turn it on. I was not able to boot into Windows 8 - CPU have overheated, problem got worst.

After performing a second attempt with thermal paste, the overheating still occurs.
My friend suggested that my stock cooler is too dusty/broken and gave me his stock cooler. Believing that there shouldn't be any problem (no dust, haven't been used) that the cooler would fix my problem.

It didn't.

According to the bios temp reading, when my CPU  reaches about 75 degrees, it's stop. CPU fan is at 2150rpm

Extra: CPU at stock speed, bios etc all set default. Problem started after my old motherboard decided not to work, replaced it with Asrock G41M-S3 motherboard which was one of the few motherboard at that time that support my CPU and is easy to purchase. 

 

Is there anything else i can do? I'm getting a new PC soon and would like to give my current comp to my dad.

 

Thanks

Are you properly installing the heatsync?

Re-sit the heatsink.Make sure no extra or left over thermal paste residue. Also see if heatsink touches the cpu.

Are you sure that it's actually overheating? It could be that the motherboard is reporting bad temps, but I don't know if it would shut itself off. Maybe just touch the heatsink to see if it actually feels that hot, if it's still relatively cool to the touch, your problem might not be the cooling.

Oh wow! Thanks for both your suggestion, After careful inspection, I found out that my uncle who I ask to install a new motherboard for me back then, didn't install all the standoffs. The top right clip of the CPU cooler was barely connected to the board.

 

I'm going to take the motherboard out and adjust the standoffs, Hopefully this will allow better connection for the CPU cooler and solve my 2 years problem.

I will post an update after i completed this.

Thanks for your suggestion, I have never touch the heatsink directly before < - Cut my finger trying today :lol:, usually I just feel the right side panel of the case where the CPU is and notice it was always warm. I was also starting to believe that the motherboard temps reading was wrong.

Well, it seem to me that the problem have been solve. The motherboard standoff was in a location preventing the CPU heatsink from completely connect. <- Such a silly mistake, Why didn't I find it, 2 years earlier.

 

Thanks BlackOutCrisis, ExDreamer and BgG286 for you guys reply.
