There were a number of problems in SP4 related to video drivers; he might try applying SP5. You can also have him try running NT under the default NT VGA drivers (it's an option provided by the NT Boot Manager at system startup; if the problem doesn't occur under the default VGA driver, then I think the source will be pinpointed petty conclusively, and if the instlal does work under the standard VGA driver, the problem may not recur when running the app.
