Restart my graphics card without rebooting?

To use Devcon I had to use very full IDs, which was too much typing and checking to insure it was correct.
I do not think that the ID you used would find it.

What I do is find a significant differance items in the whole ID
In a CMDprompt I begin like this:

Devcon.exe find *

Big long WildCard list that shows how the system defines them.

For the Video cards specific start with
Devcon.exe find *PCI*

Then I find some significant numbers for that device in the list, and use simple wild cards again

Devcon.exe find *07d1*

Then I have it down to 1or2 item, and I again See it, I add a few more significant ID items, and keep the wild cards

Devcon.exe Status *07d1*PID_3300*

I also use Status to tell its "running" or not for error control, or for checking my work.
I use Disable and Enable, as opposed to restart, but then again I am usually turning on and off.

So there is a Lazy way of finding things for sure, and testing for sure that your ID aim is close enough.

For curser problems long ago, it was easily possible to take the curser out of hardware, by reducing hardware acceleration 1 notch (before it was in a different place). You could try it, and see if your curser problems go away, and other video performance is not effected. http://www.thewindowsclub.com/hardware-acceleration-windows-7

I'm not sure if you have solved this yet, but I also wanted to do a similar thing and found it much easier.

Using DevCon just type:

devcon hwids =display

This will display the IDs for your video card, You can use any of these to execute the next command (I myself used the shortest one).

devcon restart id

Note: Make sure you right-click command prompt and run as administrator or it won't restart.
