Thanks for the prompt reply Fiery. But I have some more concerns. 1. Why it happens that sometimes AIDA64 shows iGPU sensor temperature and sometimes not. 2. iGPU sensor shoots to 107C while GPU Diode sensor remains at 65C. On reaching 107C, the system crashes. 3. If the case is faulty iGPU sensor, is there a way to disable it so that the system does not crash.

Recently my Laptop is crashing frequently. On analyzing it seems that "iGPU" temperature reaches 100C. I am using Discrete ATI 5470 GPU and its temperature reading is normal which come under the name of "GPU Diode". I have also observed that sometime iGPU temperature reading disappears. There is huge difference in GPU Diode & iGPU temperature. Normally 52C & 72C respectively. Kindly suggest why two different temperatures are coming and what could be the cause of iGPU temperature spike beyond 100C while GPU temperature remains normal. What is iGPU Temperature as my Intel HD Graphics is disabled. DELL Studio 1558 Laptop ATI Mobility 5470 1GB 4 GB RAM
