The past couple of days I noticed that my Processor on my laptop was running warmer than usual, Normal is 46-48 degrees Centigrade. It started running at 60-62 degrees Centigrade. 

 

The computer is an older Sony Vaio VGN CR190 with a T7800 Core 2 Duo. I have made no recent changes to the laptop. The only changes are regular Windows 7 updates.

 

After attempting to find a problem and not finding anything, (out of deseration) I re-imaged the Hard drive this morning with an image I made two weeks ago.   The processor is back to normal 46-48 degree temps.

 

What could have caused this problem, for now I have blocked all Microsoft updates except for Windows Defender.

 

Any ideas?????

It's possible you got a bad update. It wouldn't be the first time. I remember there was some KB update that had to do with service Wuauserv Microsoft's update service and it ran the cpu at like 100% load.

Because heat is an enemy of electronics, especially laptops, I recommend air-cleaning the fan exhausts [dc3 is a great source on how to do that].  Then using a usb-powered external cooling assembly [one giant fan or twin fans].  True enough!  Software and/or updates, "hard-drive thrashing" [maybe], can lead to proc temps rising, laptop running hotter; The cooling assembly will not only buy you time as you troubleshoot the software/update side, but also keep your laptop running cooler over all.

I could see that causing a problem. 

 

RolandJS, thanks for the reply. I replaced the T7100 processor with the T7800 back in February. The fan, the ducts were all thoroughly cleaned before assembly. Everything worked fine until Wednesday, that's when I noticed the higher temp. I took the cover off and looked at the fan, a little dust but nothing real bad. 

 

Fortunally I image the drives off all my computers the first Friday of every month. I re imaged the drive this morning and everything is back to normal

 

That's why I think this was software related. Which is weird because I thought in the Sony, Bios controlled cooling.

 

I'm going to Google updates and processor overheating. For now Updates stay off.

FWIW:  The max operating temp for that CPU is 100 Celsius.

 

AFAIK...any number of factors may increase the temp reflected for a given CPU, both hardware and software items.  My systems temps go up when I run certain apps...I assume that this is because the CPU is working harder when those apps are used for certain functions.  For me, this occurs primarily when I am running video editing programs and rendering changes/edits.
