|Hi, I have been reading through these forums for a few days now, and I was hoping that some of you experts out there could help me out a little bit. |
For a few months now, my PC has been randomly restarting/turning off when under any stress(namely when I play video games of any sort, including Roller Coaster Tycoon I). Of late, I have been under the assumption that the temperature of the CPU is my problem. Based on the information in my BIOS, as well as from SpeedFan, my CPU is supposedly idling at about 60-65 degrees Celcius, and under 50-100% load it can reach 80-90 degrees celcius. I have bought an extra fan, cleaned the case, and done just about everything i can think of to lower the temperature, all to no avail.
This led me to believe that perhaps the problem was not with the CPU itself, but with the device that measures the temperature of the CPU. I just put a temperature probe between 2 of the fins of the heatsink, with the sensor of the probe right next to the contact between the heatsink and the processor itself. The reading from the probe is a good 20-30 degrees celcius cooler than the temperature reported by SpeedFan. At near idle CPU usage, SpeedFan is reading around 70 degrees celcius, while the probe is reading 47. Under 50% load, SpeedFan peaks at over 80 degrees celcius, while the probe is in the low to mid 50's.
I am inclined to trust the temperature probe, as those numbers are more in line with what the actual temperature should be. Does anyone have any advice/ideas that could be used to make sure that the problem is actually with the device that is reading the temperature, and not with the CPU itself? And if that is the problem, what can be done to fix it, short of buying a new motherboard(which I am not really able to afford at present). Thanks in advance for any help you may be able to provide.
