Black screen at profile select/ login screen

Acer Aspire 6930-6085 notebook

Specs: Windows 7, Intel Core 2 duo t6400@ 2 ghz 2 ghz / 4gb ram
Acer Aspire 6930, had Vista, but upgraded to Windows 7 Enterprise. 4 gb ram, 32 bit operating system. Screen is smashed, but I hook up to an external monitor. Been working good, but kinda slow sometimes. I think I downloaded a windows update (or maybe it was some other update) like 2/1 or 2/2, I shut down computer and let it install. When I tried to turn computer back on, everything seemed normal except the profile select/ login screen is all black, but I can see and move the mouse. If I hit enter, or left/right and enter I can login into a profile ( but can't see which profile). The background wallpaper loads for that particular profile, but no desktop or programs. I can right click and bring up control panel. But ctrl+alt+delete doesn't work. When I press that, the mouse turns into the clock, but the task manager never comes up. I did the unplug everything, take battery out, hold power button for 30 seconds, which does work but I have to do that everytime I turn off my computer or it goes to sleep, because it always reboots back to the black login screen. My computer just downloaded some more windows updates yesterday 2/8 which didn't fix the problem. And when I looked at the windows update history, there are no updates on 2/1 or 2/2 or whenever the first update that seemed to mess up my computer was. The never updates on 2/8 are there though with all the other previous updates. I don't have any restore points, or windows disks or anything like that. Is there any fix?

It might be helpful to mention that the computer has never crashed, and I run Alvira (free edition), windows defender, and malware bytes regularly and update them frequently. Recently when I've run Alvira, it has said "Warnings:4" but "Detections:0". And I can't view the warnings for some reason so I don't know what that means. But I don't think its a virus but I could be wrong. Oh and one other thing which might be causing the problem: I recently installed Office XP because it was the only version of Office I had. It was right before the computer started doing this. But I uninstalled Office XP before these problems started because I only needed it for like one thing and didn't need it anymore. Then the black screen thing happened soon after

Unless you deliberately turned off system restore, your computer should have made a restore point just before you installed Office, and again when you uninstalled it as well as once a week. (It's not Office XP, it's probably Office '97, 2003, etc.) A system restore just now to a date just before Office was just loaded would be very helpful to you. You also could use the Windows 7 install disk to repair the system (or a recovery disk if you made one after you installed/upgraded to W7).

You have to be a little bit crazy to keep you from going insane.
