Windows 7 - Black screen at boot with safe mode, system restore, or repair mode

Hello all
First time poster with problem after peforming sys restore on Windows 7 pro 64bit.
Was troubleshooting a problem w/taskbar not staying hidden, tried to restore back 24hrs to when a java update occured. Restore seemed to proceed normally, but upon restart, it boots normally to just before the login screen would appear, then the screen goes black and all that is visible is the cursor , which I can still move.
But that's as far as it gets. Trying to boot in safe mode, or repair mode ends exact same way - can't boot in to try anything
Any ideas??

no one has any suggestions? I also triedtoboot to my Windows 7 dvd to see if I could attempt to repair but again, it only gets thru the windows bootscreen then goes black with only the mouse cursor showing as before.

I would suggest Repair Install

Yes, if only I could actually boot completely into Windows to do it.
But as I said, I can't even get that far. I get to where I see Starting windows screen, and then the screen goes black with only the mouse cursor being visible.
Can i assume that it is not a monitor/gpu issue, as I can at least see the cursor and move it onscreen?
This is freaking me out, I use this PC to work from home...

I don't think this is monitor or gpu issue. Go ahead and perform a repair install

hi ttran, thanks for your response.
However, can you walk me thru how to do this if i can't even boot windows up to login to it ?
The tutorial says to boot to windows and login as admin. So how can i even do this with a black screen??
I swapped out kybd & mouse just to eliminate then but no change
i can access bios , I hit F8 but don, get a repair option only start normally, safe mode , w\network etc but none of these choices get me a login screen

I found that i am able to boot using my Windows 7 disk so i tried startup repair. It ran, restarted pc but i get same exact result
I' starting to think that it is not windows that is the problem I can see the hhd light working so it seems like it is booting just the screen drops to black & then thats it........

a bit more info i opened the repair details and it shows :
partition table does not have a valid system partition
action: partition table repair,completed successfully
restart computer

which i do which ends up with same exact issue..

why would s simple system restore mess up partition table?

so noone can offer me any solution?
I'm trying to avoid wiping all my work files emails etc

It seems like it's a corrupt system restore or something-
I personally have two things to prepare for any disaster happening to my system:

Ubuntu Live USB on 16gb flash drive - to boot into Ubuntu and transfer files to my flash drive
Apricorn DriveWire - to take out the physical drive and transfer files like as if it were an external USB drive (got it at Fry's)

Honestly, if you cannot boot into Windows or if the Repair Setup doesn't work (which basically reinstalls the Windows 7 over your current copy), then the best bet is to wipe it clean.
