Re: Computer shuts down when to cold?
The fact that you have lag when you start programs means ur pc is having trouble loading the program. That's usually because there's heat problems, or insufficient ram/too-many-programs-already-running.
If it's fine after 15mins or so, that REALLY tends to suggest that its a memory problem. Go into the task manager and check the 'processes' and 'performance' tabs. If u see any programs running in the 'processes' tab that you don't need, try to shut them down. In the 'performance' tab, check how much free ram u have, both straight after the desktop has loaded, and after 15mins.
