    okay, so this just started up recently, where my laptop seems to get tired of being 'on' and shuts off by itself.

    I updated all of my virus protection and even tried to scan my harddrive in safe mode, but what ends up happening is that my computer, half-way through the scan, gets 'tired' and shuts off so i'm not sure if there is a virus or not b/c there's never enough time for it to scan my harddrive completely.

    basically, this happened after i updated my itunes and deleted massive amounts of programs, and did a disk cleanup as well as a defrag. i'm pretty sure that my computer shouldn't get upset about this but it does!

    so does anyone have any suggestions, b/c i really need to keep my computer on for a v. long time when i write essays or have downloads, and i really can't have it shutting down for no good reasons (other than perhaps my fan isn't working properly; therefore, my processor is overheated).

    help please!

    It does sound like either a Heat issue or a Power issue. Most other problems would result in a BSOD that would give some cryptic msg. I take it that you have auto-restart turned off, since you use the term "shuts off", rather than "restarts".

    Try running the system with the case open, and if possible a fan blowing cool air into it. Also, do check to see that your fans are ALL working correctly:
    1. Processor Chip Fan
    2. Case Fan
    3. PS Fan
    4. Video GPU if any.
