Every so often while I am browsing and working on the internet and sometimes not on-line, my laptop motor will wind up and start to run fast then all of a sudden the compyter jsut shuts off. Sometimes I will get the dreaded blue screen with computer jibberish and other times the whol laptop just shuts off completely. When this happens, it tends to shut off again 5 minutes or so later. I have run spy-bot and ad-ware stuff and get nothing. I have a Dell Inspiron 1550 fully loaded, however, I have no Macafee or Norton or anythign of that nature running. What can I do to prevent this---Ihave actually lost money playing [censored] because my machine has quit and I cannot get back in time.
