Description
When using my Intel AC7265 PCI Express card, the computer doesn't restart randomly during light internet use; however, during heavy downloads—such as torrents or a Distrowatch ISO—the screen goes black and the computer restarts after a few minutes (ranging from 1 to 5 minutes). I managed to get this report; I hope it helps.
