Windows 7: problem with Aero Peek

Dam I hate when I have problems with my PC now I dont have Aero Peek once again.
I have followed tutorial.




I even have downloaded "Enable_Aero_Peek.reg" I also runned it.. restart also done.. but still. I think it happenet when I changed my Video Card..
had to check my other HDD if it works still, because current Video Card it too long, so I'm unable to add 2nd ATA HDD, with it.

You do not have Aero turned on...the blue borders of the windows says you are running using Aero Basic which does not have Aero Peek.

Looking at the specs of the HP in you specs,

HP Pavilion a6530.sc Desktop PC Product Specifications HP Pavilion a6530.sc Desktop PC - HP Customer Care (United States - English)

it had a Nvidia card to begin with, either onboard or a 9500 GT. Did you uninstall the video drivers before swapping/adding the new card, and then re-installing the driver for the new card?

Also if you haven't, it may take running the WEI once for Aero to work.

well I didnt install any drivers when I changet my video card back to old one.. I have using my new video card for long time now. And it has been working fine. its just that my old one was little bit shorter and I just changet it for ~10min so I see if my other HDD's fould work still. And then I just changet it to back. Well I only installed my monitor driver because it didnt give me good picture. So after I had installed monitor driver I restarted my PC and so.. after that when I was done I changet back to my current video card..
Well what should I do?

Which was enough to mess up the driver for the 250. Open Programs and Features, locate the entry for Nvidia drivers and select Uninstall. Then select to only uninstall the video driver, the re-install the latest for the 250,

NVIDIA DRIVERS 260.99 WHQL

which should sort things out.

Well I tried it. but still same. But I noticed that when I had uninstalled my Video driver and after restart Windows Update started to download Video Controll and after that it started to install driver for my video card.. I only started to install NVIDIA DRIVERS 260.99 WHQL.. so I didnt now about this. but still I have taken off auto update for drivers so on..
Any new way to fix this problem of mine? Should I really have to re-install my Windows 7 what I wouldnt want to do.

You have System Restore enabled? If so go back to the first restore point before you swapped the video cards and that should restore the driver to its working condition.

I got now it work with System Restore. Good that I remembered my old password what I had on my PC.. Other way it would have been dead end xD lol
