HP 3130sa D90 Overheat shutdown problem

Hi Ive had this DV6 3130sa laptop some time now and I get a D90 overheat shutsown all the time at least 6 times a day now. Its been seen to by HP under warranty and they said there is no fauIts. Now its out of warranty so I cant get them to do it. I have cleaned the heatsink and fan and reseated the heatpipes on the GPU and CPU at least 10 times in the last 3 months with Arctic 5 thermal paste. I bought a new cpu which is an i5 460m and a new heatpipe heatsink and fan. I still get this D90 shutdown. I installed the latest BIOS F29 and this made no difference. So I installed a temp track software and it only gets to 70*C at the most before it D90 shuts down. Way below TJ temp. The fan is working and there is next to no heat felt inder the laptop ever. Can anyone please advise what else it could be before I shell ou good money for another motherboard as I love this laptop and I want to get it working perfectly.

I have also reset to factory and it still does the same D90 overheat shutdown with low temps.

I have also noted that if I remove all power inc battery and press the power button in for 20 seconds and then put all power back on it will reboot like nothing has happened. The system idles at between 29* and 35* too.

that isn't one of the NVIDIA chipset models from a few yrs back is it??

if so you may need to so some research on placing a copper shim on the GPU to act as a heatsink.. i know all the reputable repair places add a copper shim for heat transfer from the GPU..

just grasping at straws since i know nothing about your laptop

Already dont that shimming thing and it did help cool it down...... I have since found the issue I think My ATI GPU has now expired lol so now looking for a MOBO

 

check EBAY search for HP3100a MB repair. there may actually be someone who has the stuff to do it right and might only charge what they charge for reflowing/replacing that chip the shim, i know i talked to some guy in FL who had everything to replace the chip not just reflow the solder. i'll check ebay and see if i can find his phone#.
