Hello everyone, i seem to have a problem that i can't find the answer to and is somewhat hard to explain.
It started when i needed to switch PCI-E cards between a Geforce 7900gt to a GeForce 7600gs, i did so without taking into consideration any drivers installed, as i figured the drivers should be the same and it seemed like a good idea at the time, what happened was the following:
Computer booted up, loaded BIOS and continued to load windows.
As soon as windows loaded the screen turned black, to be exact the LCD monitor's back light was on (meaning the screen isn't turned off) but all its showing is black...
I've attempted to fix this in numerous way, which none have seemed to work.
I tried getting into safemode to uninstall the previously installed video drivers only to find out that safemode isn't working.
I tried using the "VGA Mode" option available in the F8 bootup menu, to which windows loaded fine.
What i did then was download a new set of drivers from the Nvidia website and uninstall the previous ones, i didn't want to install the new drivers right away as i wanted windows to load without any drivers to let the settings take effect so i restarted my computer.
After which the problem repeated itself, i was back in square one and now no option in the F8 menu had any effect.
What i attempted to do next was repair my windows using the installation disk, which also seemed like a good idea however, as soon as windows copied its needed files into the hard drive and rebooted to continue the installation i got the same problem, so now not only do i have a black screen but its also stuck in the windows installation phase (before i attempted the windows repair option i was able to access my computer via network, which meant that windows was working fine but i just wasn't able to see it)
I even tried switching monitors video cards (had an old PCI video card laying around)
which brings me here, i have ran out of ideas and am clueless as to what else i could do.
Thanks for reading!
Try installing your VC to another unit and check if it is working properly. When it works, there is something wrong in your pc. When it doesn't work, well try to check if your item is in good condition. and you stated earlier that you downloaded drivers. If ever just try to re-install the driver.
I'm pretty sure the vc is working properly as i've installed another windows on the same computer but on a different hard drive, which means that this is most definitely a software issue.
Also, i wish i could reinstall the drivers but i cant really access the faulty windows.
I think that if i could somehow reset the video card settings via the registry or maybe even delete the existing video card driver outside of windows i could fix it, though i'm not sure how to exactly...
I did it on the different computer, here are the results:

i don't know you tell me ,did it make any difference when you tried it !
Yeah sorry for the vague reply, the answer is no, it did not have any effect
novist4me: i can't tell as i don't have an onboard video on the motherboard.
On another note i tried disabling 2 services via the windows cd recovery console, one named "VGAsave" and the other is the geforce display driver, both had no effect and the symptoms are the same
