Hi all my gaming laptop/notebook was working perfectly until windows 2004 upgrade. Then the screen started going black for a second every few minutes. Contacted Intel Customer Support and was told to disable the UHD Intel 630 in order to not create conflict with the dedicated card, in this case a Nvidea MX250. The laptop now works perfectly again with the 630 disabled and the driver deleted from device manager. I cannot roll back windows 2004 and can only hope there will be a fix in the future.
