Windows Experience Index unknown error

I previously had vista installed and it performed smoothly.I did a Windows 7(x64) clean install and i kept getting the usual "cannot complete the assessment error".
I updated all BIOS-graphic card drivers and still no solution.

Heres my winsat log :

Any help much appreciated.

I had the same problem since I enabled AHCI mode for Sata controller on my GA-P55-UD3, a motherboard from Gigabyte with P55 chipset. I also had problems with other programs that analyse the pc configuration, like 3DMark Vantage, Fraps and Hardware Monitor.
The problem is probably due from the interaction from the OS, the drivers of the chipset and the bios. You can solve it by updating the bios of the motherboar to the newer version, published on the Gigabyte's site on 30 October.

If anybody have Kaspersky Internet Security 2010 then surly this soft is responsible for this issue

Do you know where the Watch Dog system comes from or why it is running?

Do you have any logs for the anti-virus/spyware or firewall programs with entries around the time you did the scans?

I don't have Kaspersky, but AVG free. The problem was

winsat\main.cpp:4736: ERROR: Unable to save validated results.

probably for same error in the implementation of the driver and the bios of Gigabyte's motherboard. I solved it updating the bios from F3 to F4 version.
Watchdog timer is a function that prevents programs from remainig locked for same error: if the program can't run for same problem, the watchdog timer terminates the program.

Unfortunately I don't have Kapersky - I have McAfee (and had this under Vista with no problem). Also my machine is a Dell XPS420 which although only 18 months old is no longer sold and therefore the BIOS is not going to be updated. Since it worked OK under Vista I guess its most likely to be a Microsoft problem with their Windows 7 implementation, but how can i tell them about it?

Although Vista and Win7 are very similar there are different systems - even if manufacturer declare full compatbility not always is fully true. I suggest to check it.

Of course classic method like update BIOS & drivers are also recommended in this issue

There was another post I saw where someone was getting pop-up messages from Gigabyte asking if he wanted it to make changes to his computer. There must be something in that bios that has more authority than I am used to.

My windows 7 didnt recognize my Phentom x4 940 processor. It is a new PC. After i updated my bios the problem was solved.

Troubleshooting Here is the answer
