I recently built a cheap office PC using an Intel Celeron G5905 (Comet Lake) and ran into a small headache – Windows Update kept installing a generic "Microsoft Basic Display Adapter" driver, and the Intel Driver & Support Assistant wasn’t automatically finding the correct GPU driver.
Visit the official Intel Communities forum and mention your “Celeron G5905 iGPU” – the support engineers there are helpful, especially if you provide your driver version and Windows build number. intel celeron g5905 graphics driver
