Hello,
I need some advice, my laptop is a dv7-4xxx with i7 720q and ati card. it is shutting down at boot after a few seconds, sometimes it's a few minutes, fan is spinning. Laptop has always been clean, I disassemble every year to clean dust and change thermal paste, but even with heatsink clean the CPU and GPU do go to 80~90°C during heavy usage and around 45~50 at idle. The screen is working, i can go to bios and windows when it is booting.
I would like to know if it's the motherboard or the processor. Is there any way to tell ?
I removed everything except processor and the symptoms are exactly the same boot then shutdown.
