Tthrottle stopped reporting CPU temps for no obvious reason

[ElGuillermo]

Hi !

I'm using BoincTasks and Tthrottle since ages without any problem.

Some days ago, two distant (LAN) Windows PCs stopped to report CPU temps.
Now I get "??" instead of XX°C values in Boinctasks (monitoring the distant PCs on my "main" desktop machine).

I've checked on the distant PCs (one is running Win11, the other Win10) :
- Tthrottle doesn't see the CPU temps anymore (blank value in the temp field).
- Tthrottle reports GPU temps (both are Nvidias).
- HWinfo64 sees the CPU temp.
- Tried to reinstall Tthrottle : no success.

I suspect this has to do with some ~2/3 weeks old Windows update, but I can't be sure of it.

Is any of you experiencing the same ?
Is there an obvious way to get temps back (without using HWinfo, which is quite overkill...) ?

Thanks !

Did you change anything in the BIOS?

Hi Fred, thanks for your reply !

These PCs are my sons's. They don't even know how to enter the Bios (yet)... So I'll say "no".
I thought about it and checked for settings that may obfuscate CPU values, but there's nothing such to be found.

The only one that could do that is SecureBoot, as it may reject unsigned code, but I have it enabled on my main rig and Tthrottle works like a charm on it.

I'm running W11 on this machine and it only runs in Secure Boot, so that's not the problem.

You can check the TThrottle log to see if it gives any errors.

OK. Something definitely happened (this is the Win11 PC) :

Surprisingly, I didn't touch anything on this PC and my son doesn't have administrative privileges, so he can't install/alter programs...
I'll reinstall Tthrottle and see what I can get from it.

I tried installing it on my W11 machine and that seems to work OK.
That said the driver is very very old (but is very stable) and I'm unable to build a new one.

I reinstalled Tthrottle on the Win10 PC.

I had some hard time to get rid of all files and had to manually delete the program's folder in "C:\Program Files".
That may be the reason why my frst reinstall try hadn't fix things (?)

Reinstall went smooth and voilà : temps are back in BoincTasks !

I just do not know what happened and why the initial Tthrottle got corrupted...

Thanks.

It's not advised to remove files from Program Files.
You never know what else is installed, in this case the driver isn't removed as it's copied.

The right way is to use Control Panel\All Control Panel Items\Programs and Features
And remove it that way.

[ElGuillermo]

Yeah, I know. But Some files were locked and uninstaller couldn't get them... So...

[fred]

Great, you got it to work, in the end that's all what's matters. 

[ElGuillermo]

Sure !
Thanks !

Update :

I found the reason why Tthrottle stopped working on two different PCs, running different Windows versions :

My kids made me install a PC game called Valorant, which uses an online anticheat system called "Riot Vanguard".
This software uses kernel-based interruptions to detect cheating tools and considers any hardware monitoring program as "harmful" and disables them all.

I was reinstalling Tthrottle on the second PC when "Riot Vanguard" told me it has "disabled" the cpu temperature monitoring program...
There is no other way to get back monitoring functionnality than uninstalling "Riot Vanguard".

Some users report to have their USB peripherals (keyboards, mice) affected too.
It's incredible how some developpers are unrespectful. "My tool will disable your stuff and you won't be able to prevent this behavior"
