After reformatting my hard drive (for the second time), the colors on my screen are only 16 bit (my other choice was 2). This happens whether I use the Restoration disk or the Windows disk to reinstall. The first time this happened my computer was under warranty and I tech support helped me. But it well beyond it's warranty period and I can't remember how I increased it to 24 bit. Could you please help? I did a search and saw one post with a similar problem, but the suggestion was to use the Restoration disk to reinstall. That won't help because I had the same problem with that disk.
