Ok, sorry if I missed this during search. I'm under the weather and brain is fried. I just purchased a license for BI, Ver 220.127.116.11 finally got all the pieces and parts to start testing everything. Optiplex I5-6500 with Intel HD 530 video. 8GB of ram. Win10Pro on SSD. 4GB Purple drive. With six cams recording, I can see BI ram usage start climbing immediately upon start. No motion or other fancy tricks setup. Direct to disc is choosen. 2-3 hrs, BI will peak at 3GB of memory use, and lockup the computer. Screen turns grey. I have to hold the computer power button down to shut it down. I remember seeing something about the Intel Video driver being the culprit in this. It has Intel Driver 18.104.22.16822.214.171.124 currently. Can some please tell me which driver may solve this? Thanks you.
