Ok, last night I put someone else's hard disk into my machine as a slave to take off some files he needed as his CPU/motherboard died. That all went through fine, took his HDD out and rebooted my computer, and it worked fine for the rest of the night.
Now however, since this afternoon (first time I used it since yesterday) I turned the computer on and the display has fallen to 640*480 pixels, and 16 colours only. I can't see what would have caused this. I try to change it, but each time I set new colours and resolution it says I need to restart and restarts in this screwed up res.
What could be causing this? I have no idea
System specs: AMD 1GHz running Windows ME with an Nvidia GeForce 2MX w/tv out.
