Hi
I am having some serious issues which I am 99.99% certain are not malware based.

I have an Asus motherboard (P5N-E SLi) that has a single nVidia 8500GT graphics card on.

I have been running this system without issue for ages now.
However, for some stupid reason I decided to see if there was an update for the graphics card and installed a "game ready" update yesterday. The installation went fine and the system appeared to work ok without issue.

However, today on booting I noticed that the bios splash screen had a load of dots on it (like the resolution was wrong) and the system would not boot up. It would get past the bios screen and then hang with a black screen and moveable cursor, then reboot in a loop.

I decided to go into safe mode and roll back the drivers, which I was apparently able to do (so the system told me).
However, the bios dotted screen is still there, and now I am unable to boot into any of the safe modes or normal mode - all result in a black screen with moveable cursor.
When trying to run into a safe mode all the drivers appear to load, and then it hangs.

I have available the Windows 7 Installation disk, a 32 bit Repair disk and HiRens Boot CD (feb 2013).

My details are:
Asus P5N-E Sli
8gb Ram
nVidia 8500GT
Win 7 Ultimate

I have updated the BIOS to the latest version available for this board with no change.

I have replaced the graphics card with two 8500GT cards on an SLi setup and this has resolved the garbled/dotty BIOS splash screen.
This has also allowed me to get back the four coloured spinning windows animation when booting into windows normally, but still gets stuck after that with a black screen and cursor.

Still trying to get into any of the safe boot modes gives me a black screen with cursor...

All I want to do is be able to remove the new nvidia drivers and replace them with the older ones, but because I cant get past this screen I cant roll back...

Please help!

Hi
Disconnected the DVD drive - black screen with cursor
Disconnected the HDD - boot from CD (Hirens Boot CD - MiniXP) booted into MiniXp

Do you think that it's not the graphics driver update?
I feel 100% that this has caused the issue to be honest...

All I want to do is use one of the older drivers to get me into win7 from where I can uninstall the new ones and do a clean install of the older driers that worked.
