Windows 7: System takes several minutes to respond normally after loading desktop

I meant Device Manager was just showing the generic VGA driver, not the Quadro 4000, so it couldn't find the appropriate driver itself. Anyway, I downloaded it from Nvidia and it installed fine.



The overall problem seems to have been caused by SpySweeper which I uninstalled prior to trying the Repair Install. When I uninstalled it, I realized I had installed it around the time this problem appeared, so I just rebooted rather than start the repair and everything's worked fine since, now after two or three reboots. I'm also running Norton 360 so SpySweeper was largely redundant anyway.

I'm keeping my fingers crossed that everything's stable again.

I'm having the same issue, I think I've narrowed it down to a USB driver but every time i reboot, it's back and so is the slow down, over 2mins to logon locally.

My system's been fine since the last post, so I still assume my problem was SpySweeper. In your case, blackace, the driver may keep being reinstalled because the device it's associated with is connected to the PC and is recognized each time you boot; if Windows can't find an installed driver it goes ahead and installs one for you. If you can identify the associated device, try

1. Uninstall the driver
2. Turn off the system
3. Physically disconnect the device from the system
4. Reboot

If your system behaves normally, suspicion will be cast on the driver. Of course, you can't use the associated device, but at least you'll know what the problem is. Hopefully, you can contact the vendor for a fix.

Problem is, it's a laptop with nothing connected!

Have you tried the manufacturer's tech support?
