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'd appreciate any help getting this back up and running asap.
