Windows 7: dwm.exe crash/no aero/will not run!

Ok, I've narrowed down the eact time this started. I'm not entirely sure this is driver related or not. If it were more people would be having this issue. All i did was install current drivers on a new laptop. That shouldn't cause all this, anyway, i've copied the error report log below. Not sure if anyone can make sense of it or not, but there it is. Keep in mind that i don't think this is a crash, the program (dwm.exe) won't start at all. Nevertheless it is generating a windows error report...I just have no idea what it means! But...once again any help is much appreciated.

I did find something you could read from Microsoft. You have this in your report.

Multiple USB Device Driver Installations Failing - Microsoft Community

Ok ill look into that, and thank you....

Thanks Jack only getting on now :)

Circa from your report you had driver updates for a usb Device as seen below:

"iusb3hub.sys 00000000`05AD9000 00000000`05B36000 0x0005d000 1 130 Dynamic Link Library Intel(R) USB 3.0 Hub Driver 1.0.4.220 Intel Corporation USB 3.0 Device Driver 3/9/2012 6:52:24 PM 4/3/2013 7:34:26 PM C:\Windows\system32\DRIVERS\iusb3hub.sys A iusb3hub Intel(R) USB 3.0 Hub Driver

Ok. I probably didnt post enough there, i don't know how to determine which drivers got updated at the time this problem occured. The modified date column threw me off, didn't realize that the program won't show me WHEN i updated certain drivers. It does show me all drivers on the system though. I could list all 31 items that the Dell and Intel sites list for me, i didn't do all of them, but the ones i did do were all from there. I was hoping the error log would tell somebody something. Would USB driver updates affect my graphics in this way?? well actually let me rephrase, they arent affecting the graphics, its whatever is stopping dwm.exe from running. If i could figure that out itd be solved. If dwm.exe would run everything would return to normal.

Ok post a screen shot of you device manager with USB controllers as shown in mine

Ok the two usb 3.0 controllers see if the option is there to roll them back

Unfortunately, roll back is greyed out on both, which i don't understand......
