Hi,
I have a desktop with core 2 quad processor, gigabyte g 41- m combo motherboard, Toshiba 1 TB enterprise HDD and 4 GB DDR 2 RAM. A few days back, on opening multiple Google Chrome tabs, the temperature of the processor started spiking to 90-95 degree celcius (the ambient temperature is 30-35 degree celcius). Then the HDD also started squeaking once a while and the system hanged for a few seconds before becoming normal again. I checked the HDD with Toshiba's HDD testing utility and my HDD passed the test.
Suddenly while using the PC the next day, it went dead. I opened the system and manually tried to switch on the SMPS by shorting it's green wire and a black wire on the 24 pin connector. The SMPS started working. I could even measure the various voltages on its connectors through a multi-meter. I next opened the heat sink of the procesor and applied thermal paste on it before putting it back on its place. I then reassembled all the clables on the motherboard and HDD.
Switching on the system, I can now see that both the SMPS fan and processor fan start running but there is no display on the monitor. After a few seconds of starting the PC, it is shutting down with a squeak sound and then restarting itself. Basically it is continuously looping from on to off to on condition. I checked the HDD connectors to ensure it does not have any loose connections.
What could be the reason for no display and continuous on-off self looping? Is the SMPS not able to supply to the PC or is it a symptom of motherboard/ processor failure? There is no beeping sound after the PC auto restarts.
I look forward to your advice.
Thanks and Regards,
Arvind Gupta
