please take out your mainboard out of the casing and turn to the back.. if there is black burn marks.. your board is bound to fail soon..
well, due to my expierence. i would recommend you to use a 3rd party Heatsink CPU cooler. which you can get from your local pc dealer/shop..
or search around for intel original LGA775 CPU replacement fan/heatsink.. get that, install that and monitor the situation in your bios Hardware monitor page..
if the problem still persist... flash your bios to the latest version. if the problem still persist.. time ot get a new board...
i removed my Motherboard and there are no black spot so i think it will work fine.
As you mention i have tried with the new heat sink Cooler Master ICT-D725-GP with the specification as
Fan Dimension: 70*70*25 mm
H.S Dimension: 83*68.5*41 mm
Fan Speed: 3300+_ 10% RPM
Bearing: Rifle Bearing
Noise: 29.8 +_ 3 dBA
But it did not worked
i could not get you in Update the BIOS software??
How do i do that..i went to Intel site and the procedure is sound little tricky as some of mention after improper BIOS update the machine is not booting
Do you have link to D865GBF latest BIOS??
Thanks in advance
pls download the bios "English: BF86510A.86A.0077.P25.EB.EXE"
if the CPU shutdown due to thermal overheating issue still occur.. i think you got a defective Thermal controller on your mainboard or your processor is malfunctioning.. i recommend you to get a new intel desktop board and processor..
i will update the BIOS and let you know.
Just a quick question is the update BIOS is required the license copy of OS because i m using the Windows XP SP2 but i am not sure about the license as i have formated my corrupt OS and reinstalled it with non license copy.
Here are some statistics that will help you
BIOS Version BF86510A.86A.0063.P18
Processor Zone Temp 77C/ 172F
System Zone 1 44C/ 111F
System Zone 2 54C/ 129F
Processor Fan Speed 3040 RPM
Rear Fan 0 RPM
Front Fan 0 RPM
+1.5 Vin 1.454V
Thanks in advance
i tried to update the BIOS again and now it updated properly the version is now changed but the problem is seems to continue .
just another question is might this problem is due to the bad Power Supply (SMPS - Swich Mode Power Supply) of the cabinet??
should i tried by changing it or something or just buy new motherboard??
i had same problem on 845glva board years ago the problem was fan it was loose hardware person told me that silver plate shold always be kissing/touching processor otherwise it will behave like this always i tested this nd that guy was right u know what i did i pasted fan to my processor with fevicwik(adhesive) it never wept again!!! it may look funny but it worked for me :-)
I have had problems with Cooler master heat sinks. Some are not machined properly and sit on top of the plastic pins that hold the frame to the motherboard. Then heat sink is raised enough to NOT make contact with the processor. It LOOKS like it's down but there is a gap so not cooling at all. The genuine Intel heat sinks are recessed along the bottom edges to provide clearance. I had to machine the corners down on two of the Cooler masters recently and work fine after that. If yours is completely flat out the the outer edges this could be your problem since you said you changed the the heat sink/fan and it got worse. Good luck.
