Hey folks,
I'm new to the forum so please forgive anything I screw up in protocols.
I have an older Dell Precision M65 running XP Pro ServPack3. I keep it tuned so it has been running fine until recently. Now when I turn on it runs fine till it overheats and then it will eventually get so slow the processor idle time goes to zero and processes eat 100% of the CPU time.
I believe I have determined that the issue is the CPU fan does not run and when processor gets hot, it throttles back. Here is the only evidence I have so far . . .
I managed to get info to look at the "Thermal Control Panel" by holding down keys Shift + Fn then entering 1, 5, 3, 2, 4. Release all then hold down Fn and hit R. This brings up the panel.
When having issues the max positive values all change to 127.:
When it is cool and runs fast the 127 values are all reduced to around 60 degrees: (Pic I have of panel is too big to post here)
I DO NOT KNOW but it looks like the min and max temp values for turning the fan on and off from various component temps in the first pic are set to max input values of -128 and 127 degrees something (Fahrenheit or Celsius) and of course will never turn on the fan. Computer gets hot and throttles back.
Please note iwhen the computer first comes on the positive values are lowered and it appears the fan will come on. However, after some time running these values change to the max value of 127 then overheats and throttles back.
I have looked through BIOS and cannot find anywhere where you can manipulate these values. I have tried setting the MSR CPU auto throttling to disabled and setting the throttle manually. The values only change back to the max values shown in pic1. I'm not even sure if the values in pic2 are the default values.
One thing, my computer used to run fine till I had issues with Outlook and ran the fix tool. I believe the reason for the issues with Outlook were related to a virus that has been cleaned (I hope). After all of this I could not get the fan to ever come on at fast speed. I DO NOT BELIEVE THIS TO BE DUST, DIRT, DEBRIS, OR THE CHIP SET. I think something is/has manipulated the values in the panel and is preventing the fan from coming on.
ANYBODY have any ideas!? Anybody with a Dell Precision M65 know what the default values should be? How do I fix this issue short of Format C: and start over!!!!???
