Whenever i am doing stuff on the internet (usually using JAVA) my computer will randomly shut down,it will automatically restart, then in the startup process it will restart again etc. until i shut my computer down completely. Then i have to let it sit for a while until i can use it again. Some times the browser will just shut down but usually the whole computer. Sometimes an error message will appear on my desktop after. it is labeled "HS_ERR_PID(random#)" if you would like to see this please tell me.
