My Toshiba satellite l675d-s7104 keeps freezing up and the McAfee antivirus software I installed keeps telling me to renew, when I already did. Has anyone encountered a solution to this particular issue?
I can't address the McAfee antivirus issue but I had a Toshiba what would freeze and often shut down due to it overheating. If overheating is a possible cause you can clean (blow out with compressed air) the exhaust vent.
I have an L675D-S7104 and get blue screens on occasion. The trouble with Toshiba is they do not update drivers. I would suspect that the freezing issue you are experiencing has everything to do with driver or IRQ conflicts. Best thing you can do is make sure all your drivers are current.
