hello. I have a friend who I'm trying to help. his computer is a bit on the older side but his graphics card is newer (1060). he keeps having an issue where his computer either blue screens or alt-f4s the game he is playing due to memory. I've tried just about everything I know as thus follows. virus scan, malware scan, memtest, defrag, uninstalled useless programs, autostart cleanup, and tried updating drivers. next step is hirens boot disk to try and clean up some more stuff if I can. any suggestions will be taken seriously. thank you for your help
