win7 boot manager error.

I'm stumped here. So last night windows gives me a dx10_1.dll error.... says the.dll file is missing. So i reboot and find the same error, search around and end up downloading the .dll file and pasting into the windows > system 32 folder. Reboot and still have issues.

Fack it. I just figure i will reformat, so i start fresh install and end up with a boot manager error upon the first automatic reboot of windows. Requests restart and just loops.... i have tried 3 installs on a fresh formatted drive. I don't know how well win7 formats though as it takes less then 20 seconds to wipe a 500g hd... xp took an hour. W.t.f. over. Any ideas?

My Windows 7 Start is Extremly SLOW

I'm seriously running thin on ideas. Try what FordGT suggested? Also if it is indeed a HDD/Network issue, you could maybe set up Windows Resource Manager to start at boot and look out for any weird HDD/Network activity.

 

UAC prompt for Task Manager. MMC blocked. What happened?

It's possible that Computer Management is being blocked by SmartScreen. We suggest disabling it and see if it helps. Follow the steps below:

1. Click the Start button.
2. Type smartscreen in the search bar.
3. Click Change SmartScreen settings.
4. Click the drop-down arrow in the Security row.
5. Click Change settings beneath the WindowsSmartScreen row.
6. Click Don't do anything (turn off Windows SmartScreen).
7. Click OK.
