Windows 7 pauses for 2 minutes with black screen while starting up.

AFter starting or a restart, the following happens.
Windows shows a welcome screen.
It looks like a normal startup.
The screen goes black.
There is no activity on the Hard Drive Light.
For two minutes the screen is black.
Then the screen comes back, and the startup proceeds normally.

I have run Malwarebytes and removed anything found.
I uninstalled unnecessary programs.
I ran Performance Toolkit and tested and repaired the registry.

AVG Internet Security is Installed.
AVG PC Tuneup has an exclaimation point on the taskbar.
When I click on it, the menu offers me the chance to turn it on, which I don't.

The computer has been coming on.  The wait is disturbing.

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing.

Did you run chkdsk?
If the computer has extra hardware attached you might want to try to only connect keyboard, mouse and display and disconnect all other hardware.

If this doesn't help and you have the option to install software you might try to run a boot trace to identify the problem. For this you can use the "Windows Performance Analysis Toolkit (WPT) for Windows".
To identify the problem via this method can be very time consuming unfortunately.

I don't use that AVG PC Analyser either please ignore until it goes away. I find it offensive as it's forcing us to either put up with question mark or scan. It eventually goes away
What I'd look at is the scheduled scans is it set to run at boot?
Click the arrow at Options> at the top right
Then open Advanced Settings
expand the + sign next to scheduled scans

i also suppose it can be an external device - causing the wait (printer, scanner, disk...)
it can be also some task running at startup - you can check that with msconfig:
run msconfig - select startup tab
click disable all - and reboot to test

you can try the free panda cloud AV instead :

Autoruns would be another way to see what programs are starting at boot.
Can you maybe try to start Windows 7 in safe mode by pressing F8 at startup and then check if the problem is still there ?
For decades, all security experts keep saying that scanners are not reliable. They can only detect and remove what their patterns know, furthermore they often have a hard time doing so when being used while the virus is active.
This is still ignored by many for some reason.

Scan your system offline with an AV bootdisk, there are some free ones. If no better, resort to the latest backup. If no backup, reinstall windows after thoroughly saving your current data.
computerlarry--Look in Event Viewer to see if there are any Error messages during those two minutes.
computerlarry - how is it going?  throw in some details for follow up

Great response. Lots of information for diagnosing future problems.

A Malwarebytes scan found something that was initializing during startup. Speed improved afterwards.
Great. You got your speed improved. :-)
