Windows 7 won't boot up after update

[Guest Tommy C]

I'm running Windows 7 Home Premium on a home built desktop with an Asus A8N32-SLI Deluxe MB, and an AMD processor. It only has a single 160g HD. Automatic updates are turned on, and it has AVAST IS for virus protection.

 

Here's the problem. I came home from work the other day and the computer was frozen up, so I had to hit the reset button to reboot. When it came back up, it would get as far as the "starting windows" screen, then everything would go black and non responsive. I think the computer was in the process of updating when I left for work.

 

I've tried to use the repair console, and it keeps telling me it cannot start the repair tool, and it will not go back to a known time through system restore. For some reason, I cannot get it to "safe mode" either.

 

The other morning, I placed the Windows 7 CD in it hoping to repair it that way. For some reason It cannot find my installation of Windows 7. It keeps telling me the only image of Windows 7 is on the "D" drive. I do not have a "D" drive. When I attempted to load drivers (hoping to atleast get into safe mode), I found it apparently thinks I have 3 drives in the computer. "C" drive is now listed as System Reserved (with 70.3 mb free of 99.9mb), "D" is now called Local Disk (with 110 gb free of 148 gb) and something called "X" drive listed as Boot (with 28.9 mb free of 31.3 mb). My CD drive has been relisted as "E" drive, and shows that I have the Win 7 CD in it.

 

I cannot get into safe mode. When I hit F8, it takes me to a screen that asks me to choose which device to boot from. If I do not use F8, it takes me to a screen that asks me to launch the repair wizard or start windows normally. Last night I was actually able to start the repair wizard, but it didn't fix anything.

Today, I finally got it to atleast ATTEMPT to run the startup repair. After running it 6 times, I get the same reports. Here's what I get:
