PC Wizard not showing GPU temp.

[Valbruch]

Hi,
My PC recently got a new Motherboard. The old one died but the new on is pretty much the same.

The thing is that after getting my PC back from repairs I installed PC Wizard (http://www.cpuid.com/pcwizard.php) but it doesn't show my GPU's temperature. I used the same program before and it worked but now it only shows a model (nVidia GeForce 275) and fan speed but no temp.

I use teh 196.21 drivers.

Does anyone know why it no longer shows the GPU Temp. ? I'm not really a hardware expert so I don't know if the monitoring sensor has to be plugged somewhere (or if it even is pluggable ) ?

It's not as if I had some issues with the card but I feel uncomfortable not knowing my GPU temp, especially when related to fan speed which pretty much stays 40% no matter what...

See if you can get it working with another application like EVGA Precision Tool and I'm pretty sure you should be able to check the temperature via the driver interface.

I tried Evga Precision and HW monitor ptograms and it didn't show in either one.

But,

your post did help me to find the answer eventually and for that I thank you. I searched for the solution on several sites, forums... but I finally found it on Evga forums. It seems there is a bug in all 19x.xx drivers that might sometimes result in this issue.

That's an internal issue of all currently available 19x.xx series.

Problem background:
Since 190.xx series NVIDIA driver's internal resource manager is trying to precache thermal sensors information in the registry during the first startup after installation. This mechanism doesn't seem to work fine yet, under some conditions sensor detection and precaching algorithm can fail and store incorrect sensor type information in the registry causing temperatures to disappear till the ForceWare re-installation.

Temporary solution:

Until the problem is not fixed by NVIDIA, there are still some temporary tricks allowing to solve it. First, you may just perform complete Foreware re-install, this will also cause precached thermal sensor information to be removed from the registry and to be re-detected by ForceWare on the next start. Second, you may manually remove corrupted thermal sensor information from the registry and this way cause the ForceWare to re-detect it on the next reboot. To do it open regedit then search and delete all instances of RmThermalProviderInfo and RmThermalProviderNum entries in the registry. Then reboot.

And let's hope that it won't take long time to fix it from NVIDIA side.

This is a quote from that post. This solution really helped me and now temps show in every program I tried.
