Problem: In games, the screen will freeze up and repeat sounds over and over. If I switch desktops sometimes it will allow me to escape, I have this same error on Cinnamon, LXDE, LXQT, XFCE, and i3. The issue happends in groupings, entire days can go by without a single crash, sometimes every time I launch a game at least once, or within seconds of getting back into a game. consecutavily until theres nothing I can do but abandon the game. This really sucks because I play competitive CSGO, and constantly having to reboot ruins games and frustrates me + everyone else involved, I would prefer not having to go back to Windows. so, heres what I know: Hardware: 00:00.0 Host bridge: Intel Corporation 4th Gen Core Processor DRAM Controller (rev 06) 00:01.0 PCI bridge: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor PCI Express x16 Controller (rev 06) 00:02.0 VGA compatible controller: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics Controller (rev 06) 00:03.0 Audio device: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor HD Audio Controller (rev 06) 00:14.0 USB controller: Intel Corporation Device 8cb1 00:16.0 Communication controller: Intel Corporation Device 8cba 00:1a.0 USB controller: Intel Corporation Device 8cad 00:1b.0 Audio device: Intel Corporation Device 8ca0 00:1c.0 PCI bridge: Intel Corporation Device 8c90 (rev d0) 00:1c.2 PCI bridge: Intel Corporation Device 8c94 (rev d0) 00:1c.3 PCI bridge: Intel Corporation Device 8c96 (rev d0) 00:1d.0 USB controller: Intel Corporation Device 8ca6 00:1f.0 ISA bridge: Intel Corporation Device 8cc6 00:1f.2 SATA controller: Intel Corporation Device 8c82 00:1f.3 SMBus: Intel Corporation Device 8ca2 01:00.0 VGA compatible controller: NVIDIA Corporation GK106 [GeForce GTX 660] (rev a1) 01:00.1 Audio device: NVIDIA Corporation GK106 HDMI Audio Controller (rev a1) 03:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.
