Bad card, drivers, reinstall dx9b or something else?

My TnT2 Ultra always had that problem and I always had a heck of a time getting it to run Half-Life. It wound up being the drivers I think. Sorry I can't be more helpful, but that was a while ago...

Its a driver issue, had the same thing happen here when I installed the 3.8 drivers recently, I switched to the Omega drivers and all is well.

Same problem, using FX5600, went to older drivers 44.03s solved the problem.
