Error loading operating system

[o0 o 0 o o0]

I recently downloaded a media file, im not sure if its corrupt or not but i have reason to believe it is.
The colours went dodgy (only 4 colour bits and 600x800 sommin resolution and it wont allow me to change anything).
Then i shutdown windows and tried to restart, i out in my recovery diskette but that made it worse. now i started the computer, its about to load up but a message says "error loading operating system".
I tried using a AV disk using BIOS setup and tried reinstalling windows, but it doesnt help.

Any ideas to fix this?

Assuming you have Windows XP from your 4bit colour setting. Sounds like it might be a display driver problem. If you completely re-intalled Windows, you need to install motherboard drivers and video drivers if they are seperate.

If you need more help, please try to post more details as to what happened and what you did exactly.
