Computer freezes when running Windows Experience Index

what is your power supply?

First, i suggest you to replace your PSU.
CIT is not a good PSU, cheap and generic one and don't really have decent internals.
If you can find an Antec, Corsair or Seasonic.

Even seasonic 350 ss350 or antec earthwatts 380 is much better than CIT unit.

This, I wouldn't be surprised if it eventually failed in the next few months.

Replace it as soon as possible before do some damage to your hardware..

sweet..

Eureka! I found it! I've looked everywhere for a fix to the problem of my Windows 7 computer freezing up every time I try to run the Windows Experience Test (it crashes at the “Tuning Windows Media Decoding” test). But until now I haven’t found a solution that works on my computer (I'm using Win 7 (64 bit) with an Intel Core 2 cpu with 6 GB RAM and an NVIDIA GeForce 7300 LE video card.)

But then I stumbled across the "falconfour's perpetual musings" website.

He has an article entitled, "Disable DXVA to fix Windows 8 BSOD on Experience index test." I figured that was close enough to my experience to try what he said to do, and it works!

Go to his website to find out what do to, or keep reading..

Go to http://bluesky23.yu-nagi.com/en/ and download BlueSky’s DXVA and install it onto your computer. It runs without installing anything permanently on your computer. This is what you will see when first run…


Click on the “DirectShow/MediaFoundation Decoder” button. You’ll now see…



And then click on DSF/MFT Viewer in the lower right…

You’ll then see…



Notice at the top left there are “DirectShow” and “Media Foundation” buttons.

Select "Direct Show" button and scroll down to first red-highlighted option (on mine it's "Microsoft DTV-DVD Video Decoder", but it might be different on yours).

Select "Microsoft DTV-DVD Video Decoder" (or whatever) and right pane will become active.

On bottom right you'll see "GPU Acceleration" button

Click on "GPU Acceleration" button and you will see the options:
Enable DXVA
Disable DXVA
Initialize
_____________

Enable DXVA2
Disable DXVA2
Initialize

I found that I only had to disable the DXVA2 option, but who know, you might have to disable both.


Now go back to the "Direct Show" button pane on the left and scroll down to any other red-highlighted option, I didn’t need to disable any of these (it was only "WMVideo Decoder DMO"), but keep trying until you can run the test and it works!

Select that red-highlighted option (whatever it is for you) and then select the "GPU Acceleration" button on the bottom right.

This will likely have just three options, "Enable," "Disable," and "Initialize." Select the "Disable" option.

Do these steps for any red-highlighted options in both the Direct Show and Media Foundation button options.

When I clicked on the Media Foundation button I saw that there was the “Microsoft H264 Video Decoder MFT” option red-highlighted. When I enabled it the test FAILED SPECTACULARLY! So I disabled it again and it runs well. I suggest you try the same.

I also had “WMVideo Decoder MFT” highlighted. I found that if this was enabled the computer froze when the Win Exp test was run. So…disable it!

Those were the options I had, and now, the Windows Experience Test doesn’t crash when run. Hurrah to Falcon Four!

Did you ever get this fixed?

I changed Graphic Properties - 3D - Disabled Application Optimal Mode.
