Hi, I have a Pentium 4 3Ghz CPU installed on Intel D101 GGC Mother Board. This computer is 4 years old. It had been running fine so far, but now, my computer was just getting hung or shutdown itself intermittently. When I checked, i found the CPU was getting heated up to 110C as shown in my hardware monitor in bios. I opened all the chasis doors and i even worked with A/C swithced on. I don't seet the temperature going down below 100C or 98 C. I would like to know what can be done or what would have gone wrong. I also reassembled CPU HeatSinkFan after cleaning. I also tried operating my system by keeping my Mobo outside the chasis with a/c turned on. Please help.

It's highly unlikely your CPU got up to 110C...it would have shut down long before getting that hot. I'm not saying you don't have an overheating problem, but I do doubt the accuracy of the temp reporting. "I also reassembled CPU HeatSinkFan after cleaning" By that I assume you removed it, cleaned it, then reinstalled it? Did you use thermal paste? A tiny dab approx the size of a grain of rice in the center of the CPU? Find your CPU on this list & follow the application instructions regardless of the brand of paste used: http://www.arcticsilver.com/ins_rou...

Jam, Thanks for your quick reply. The temperature i mentioned is what i saw in BIOS. it started from 85C and went up to 110C. All these time, i was only in BIOS. if i tried to get in to windows, system will just shutdown. Well, I didnt know about the thermal paste. But, when i remove the heat sink fan, i did see some paste like stuff lying inbetween. But, I mistook it for some sticker that would have got melted in such a temperature. I will get that arctic silver 5 and try that. And, where can i find which thermal paste would suit my intel P4 3Ghz processor?

$3?! OMG, it went up a dollar sometime in the last 5 years or so. "But, I mistook it for some sticker that would have got melted in such a temperature." Yeah, that stuff is made to melt ~58°C; it's called Thermal Interface Material. Skip

Thanks for the site and info. on thermal paste. I'm in India, so I will have to hunt around electronics market in my city to get one. Before I do, I have some questions. You say that my computer should have shutdown before the cpu could have reached to 110C, but you know what. I tried working on it again with my a/c turned on. I checked again the temperature. It was still above 100C, it was going up to 110C still. After I login, if I allow it to stay idle, it can be so for a while. Rather, if I open an IE and browse, it would just shutdown itself. And, my question is when my pc is shooting up to 110C and 112C which is abnormal, how much can the thermal paste help me. Can that reduce 50C?? if so I shall hunt for it. And, if not, should I have to search for a new processor which suits my Intel D101 GGC Mother Board? Your thoughts please....
