The windows experience index for your system could not be computed — could not measure windows playback performance
windows experience index problem
i cannot rate my system.. i have an acer 4741G notebook.. i recently updated my nvidia driver to the latest one.. my graphics card is the nvidia geforce 310M.. after updating my driver, when i checked my performance rating.. it was unrated.. so, i clicked the ‘rate this computer’ button.. then it rates my computer.. until its about to finish rating.. just before the rating process finishes, an error prompts.. it says ‘the windows experience index for your system could not be computed’.. next, ‘could not measure windows playback performance’.. i wonder why and how to overcome this problem.. can someone help me? please.. thank you..
I am sure that this has something to do with your upgraded graphics card as the error indicates playback performance.
1. Have you installed the latest drivers for your graphics card from the Manufacturers’ website?
2. Do you have Kaspersky Antivirus installed on your computer?
On my research on this issue, I find that this issue can be resolved by reinstalling the drivers for your new graphics card.
I suggest that you reinstall the drivers for your graphics card and check if you have the same issue.
Reinstall the drivers for your Display adapter.
a. Click Start. In the Start Search box type «devmgmt.msc» and press Enter.
b. Expand «Display Adapters», double-click on the entry of the display adapters.
c. Click the tab «Driver», click «Uninstall».
d. Click Start. In the Start Search box type «appwiz.cpl» and press Enter.
e. Remove the entries related to the display adapter.
Then reinstall the driver with your driver CD that came with your computer.
NOTE: Don’t uninstall the drivers until you have the source to install the drivers back to your computer. Also create a system restore point before you uninstall the drivers. Refer this article on how to create System Restore Points Manually.
This article is for Windows Vista. However, applies for Windows 7.
Once you uninstall the drivers, you can download the latest drivers from Nvidia website. http://www.nvidia.com/Download/index5.aspx?lang=en-us
Use the second option ‘automatically find drivers for my NVIDIA products’.
You can also refer the below threads in which other users had the same issue.

The reason you’re seeing this message is because Windows 7 allows for video decoding to be performed by the GPU (Graphics Processing Unit) and your system does not seem to support the new video acceleration introduced.
I would suggest you to try the steps mentioned below.
Obtain the latest version of Video drivers.
Refer to the link below for more information.
Update your BIOS(Basic Input Output System). Firmware
I would suggest you to contact your computer manufacturer to see if they have any updates for the System BIOS.
Modifying BIOS/complementary metal oxide semiconductor (CMOS) settings incorrectly can cause serious problems that may prevent your computer from booting properly. Microsoft cannot guarantee that any problems resulting from the configuring of BIOS/CMOS settings can be solved. Modifications of the settings are at your own risk.
Did this solve your problem?
Sorry this didn’t help.

First of all thankyou for your reply.
I dont have kaspersky but Avast.
I used Experience index before that time it was completed and my index was 4.9. But now it shows error. My graphic card Nvidia 8600 GT is up-to-date. So can i upgrade BIOS.
I sometimes go to Intel website and use there automatically find and update tool and it does not shows any BIOS update recommendation.
Once again thankyou very much

What is your computer make and model?
Event Viewer Reports
1. Normally when an error occurs on your computer looking in Event Viewer should be your starting point for finding a solution. Most system related errors are logged and getting an exact copy of the relevant report is important. Unfortunately understanding the reports is not easy and most computer users need help with their interpretation. I have more to say later on interpretation.
2. Event Viewer comprises three main Windows logs. These are Application, Security and System. For troubleshooting purposes System is by far the most important.
3. To access the System log select Start, Control Panel, Administrative Tools, Event Viewer, from the list in the left side of the window select Windows Logs and System. Place the cursor on System, right click and select Filter Current Log. Check the box before Error and click on OK and you see only Error reports. Click on the Date and Time Column Header to sort. You may need to click a second time to see the latest Report at the top.
4. A tip for posting copies of Error Reports! Run Event Viewer and double click on the error you want to copy. Click on the Copy button to place a copy on your Clipboard and close Event Viewer. Now start your message and paste into the body of the message. Make sure this is the first paste after exiting from Event Viewer.
5. There are three types of Report, being Information, Warning and Error reports. In most situations it is Error Reports that offer the best information but occasionally Warning Reports provide useful clues.
6. All reports have date and time stamps and when troubleshooting it is important to concentrate on more recent reports. Study reports since the point when the computer was last booted and then check whether a similar report appeared in the previous session. If errors do not repeat investigation as to why they occurred is wasted effort.
7. Within individual reports the more important information is Event ID and Source as these help when looking for help on the internet. The description is equally important and copying the exact text for use as the search criteria greatly helps getting better results when using Google. Do not paraphrase descriptions when asking others for help.
