PC overheating(?) at stock speed...

[UlricT]

I bought a system (ECS K7S5A, Athlon-C 1.2ghz, 384MB, 2x40gig) last september, and it has been running without problems from that time. But in these past few weeks, it has been randomly rebooting (i suspect only during times of high CPU load) . Suspecting overheating (the room temperature is like 35C), i installed Motherboard Monitor 5. The temperature reading was almost off the scales - 96C!! I went into the BIOS, underclocked, and the machine is runnig ok, although much slower. Do temperatures go this high on chips? Is it MBM that could be be giving wrong readings? Any help would be appreciated. I do not use any specialised cooling solution, but for CPUs that are not overclocked, i don't think that should be a problem.

Any thoughts on this would really be appreciated.

Well... i suppose this is a bump...

No thoughts? none?

MBM can give false readings, my roommate had a problem with that today. He told it the wrong motherboard, and it gave a temp of 90C. Check the CPU temp in the BIOS. 96C is possible, and it is around (above) the die temperature of the Athlon. What heat sink and fan are you using? Check that the CPU fan isn't broke or only running some of the time. It seems werid that the problem would start after running fine for a long time.

well... the room temperature was cooler when i bought it, so maybe that could contribute to the increase in heat? Also what IS the normal running temperature for an Athlon 1.2 Ghz?

Oops... just checked!! MBM seems to have 2 options.... SIS950/ITE8705F-3 and SIS950/ITE8705F-3 diode. I was using the diode option. Stoopid me. My proc don't even have a diode.So what else could be casuing these random reboots which were solved by underclocking the processor? ( I have left the memory at 266DDR, just changed the CPU multiplier to 100mhz)

Thanks for the input theBDB. It is really appreciated...
