The lack of a basic NetWare environment makes it difficult to do any meaningful troubleshooting. Check your hardware vendor's Web site, and download and install any updates. If the BIOS and firmware updates are not the problem, one of your NetWare drivers may be corrupt. Follow the procedure and change only one thing at time.
Patience is key.
