AIDA consumes CPU time and HDD when idle

Recommended Posts

Most of the time I have AIDA running for a single purpose: show HDD temperature in the system tray. So AIDA stays minimized to the system tray with only one sensor visible in the tray as well. For this single task AIDA constantly consumes 10% of my CPU power and constantly searches something on disk. It is a laptop and I want my CPU and HDD stay idle as long as possible. Procmon shows that AIDA constantly searches for a file sqlctr90.dll in all paths listed in the PATH environment variable and also constantly goes over about one and half thousand registry paths. I understand that this is maybe a very important file. But why to search it over and over again and so frequently? One time is not enough? Why read so much registry information so frequently when all it shows is a single sensor value in the tray?

That .dll is part of SQL Server Performance Acquisition DLL, I believe from version 9 of Microsofts SQL server.

Now AIDA64 might be using that but I can tell you on my sytem that AIDA64 is monitoring everything it can Resource Monitor shows AIDA64 averaging 0.64% use! so at 10% I think something else might be going on in your system.

What frequency of system polling have you set?

No, these 10% are definitely from AIDA. I can see it with procexp and procmon. It maybe 0.64% on your system with I7, but I have just Core 2 Duo on my laptop.

I didn't set anything. It is default to 5 sec for the system tray icons.

AIDA64 doesn't use the mentioned DLL at all, and it doesn't use SQL Server services. It may use a driver or another DLL that depends on those services though, so we need to investigate this to provide you a proper answer (and hopefully a fix too).

Please let us know more about your system:

1) Notebook model?

2) Windows version, kernel type (32-bit or 64-bit), Service Pack applied?

3) Any external disk drives (USB, eSATA, FireWire) connected?

Thanks,

Fiery
