Bought this desktop local, but found the following issue: It always hang or crashed when streaming 4K video over youtube, change the setting to 1080p seems OK, I understand there is no discrete GPU equipped on this desktop (only the intel onboard one), so, I was wondering if the issue is due to lack of sufficient GPU equipped or its hardware failure? Can anyone give any clue? Thanks, Update (08/21/2021)
Here are the pictures I took when the system got crash/frozen during the 4K video streaming.
I think you’re hitting a thermal issue! I would install a good thermal monitoring app like this one TG Pro I think its the best and not very expensive if you get the full version. Here we only need the trial level. Start off taking a snapshot of the main window (adjust the size so all of the sensors are visible in one window (no slider on the right) when you are not running anything (baseline), now do another when you are watching a 1080p Youtube vid and then one more watching a 4K vid. Make sure you’ve labeled them and post them here for us to see Adding images to an existing question
