hi buddy 
i agree with Cloakster coolinjg problems coz the pc wotn crash or restarted tiself or stop the HDD itself unlss there is an Overheated Processor , try to turn it off if you're using the laptop for long hours and keep it off for like a 30 minutes or something or turn off the programs using the video card while you're playing GTA
, or if you've infected with a virus try to format and install a system again incase you've got warranty you better get it back to the shop they will replace you a new one either fix the problem
hope i helped you
