I shutdown my computer and the next day at start-up all I got was a
black screen with a moveable cursor, however I did manage to run the
program in safe mode and after doing a restore to a previous version it
now won't even run in safemode, all I get is the same black screen and a
popup with the message..
"Runtime Error! Program: C\:windows\system32\nvvsvc.exe This application
has requested the runtime to terminate it in an unusual way. Please
contact the application's support team for more information".. I removed
the hard drive and scanned it for problems in another computer using
Spybot and Avast anti virus, Spybot did find several problems which were
removed, however after almost 2 hours Avast found absolutely nothing and
on reinstalling the drive back into the original computer I still have
the same problem, can anyone please explain what's happened and how I
can get my computer working again TIA.
The indication here is, the file has a legitimate name. We
can't know at this point, whether it's the original file or not. Now, if
you didn't have an NVidia GPU or video card, we'd be suspicious it was
malware.

Drivers run in Ring 0 and are part of the kernel space. And
if there is a problem with them, then the computer can "fall over".
Yours doesn't seem to have entirely done that, because you managed to
get a movable cursor and black screen. Perhaps the video portion is
using the default VESA driver, and is currently stuck at the point
it tries to load the Nvidia driver or something. (For that matter,
it could even be some other driver, but we do have the evidence of
the error message to consider, which names and shames nvvsvc.)
What you need to do, is remove the Nvidia driver. What I can't tell
you, is exactly how you're going to do that, since neither Safe
Mode nor the regular mode of operation are working. If I were to boot
an alternate OS in this situation, I wouldn't be able to tell you
where to start, to remove stuff. Enough of the driver would need to
be removed, such that the OS would not attempt to load the driver.
So it's not necessarily all the driver files, there could even be
an INF somewhere tempting the system to load that driver.
You would think Safe Mode would work - at least, as long as the
NVidia driver is not being loaded when in that mode. Try to make
sure if you're entering Safe Mode, that no video driver is loaded
if you can manage it.
There is a picture of the Safe Mode options here.

I see an option "Enable low-resolution video" - perhaps that uses
VESA mode for the video card ? And then, that NVidia driver wouldn't
be used.
Maybe someone else knows whether that's a "Safe Mode" or not. Maybe
it just stops the proprietary video driver from loading ? I doubt
the purpose of the "640x480" part, is because there is something
magical about it. I think the "640x480" is trying to tell us,
the video will be using the (dumber) VESA driver. Which doesn't
need things like "nvvsvc".
If you can get to the desktop, then you can try removing the
NVidia driver.
One tricky aspect of drivers now, is some are "built-in" to the OS.
Later, you can install a manufacturer version, a later one. If you
had installed a manufacturer one, that would be for the best, because
there might be less of a problem removing it. If the driver was
something which shipped with the OS, it's not going to be in
"Add/Remove" (Programs and Features or whatever). It might be
harder to stop a built-in driver from trying to load.
You haven't told us, what kind of computer this is. For example, if
the computer had two video options (a built-in chipset video and
a separate video card), maybe you can make progress by removing
the video card or disabling it, and connecting the display to the
built-in video. Using a hardware trick is a long shot, but
perhaps if there are no other options, it'll be something to
try.
