Half-Life: Direct3D Works Fine, OpenGL does not like HW.DLL

AMD K3-450mhz
Gigabyte 5AA Mainboard
128 MB RAM
Inno3d Tornado Geforce2MX 32MB
Windows 98
Detonator 3 6.49 Drivers (from manufacturer)

Half-Life runs fine in Direct3D, but in OpenGL, it crashes randomly with a GPF - HL.EXE has an error either with <unknown> or HW.DLL. An solutions people?

Sorry m8, but I can’t answer your question.
My problem is: When I start HL, it gives me an error in opengl.dll and then quits.
Any suggestions? I tried to reinstall the drivers allready but it doesn’t help.
