Hallo all
After spending two weeks pulling my hair out, reading every forum I could get my hands on and leaving messages, downloading latest drivers, formatting disk, re-installing windows, updating chipset and downloading latest version of DirectX9. Nearly giving up because there was no answer in sight, I took PC in to find that I had a faulty graphics card that worked with everything except OpenGL. The card was replaced with the same type and everything worked perfectly. Nvidia Geforce 2 MX400. I am now having great fun with MOHAA and wish that I had checked this sooner.
Check your card before attempting too much troubleshooting.
Many thanks to VC6-OGL for all the help.
Happy Gaming
