  1. Hi,
    I have been using my computer last four years. I never shut down my computer. It was on 24/7. lately I am having problem with it. While I am working on computer or away from it for more than 2 -3 hours system automatically shuts off. I checked all sources possible I think of... I have kept "never" shut down. removed fan from CPU and put new one + cleared all dust inside CPU using vaccum + reviewed bios reads correctly. + checked Power connector and it works fine too... Please help...

    Do a power supply swap with a new one and see if that corrects your problem.

    Does your computer shut down safely (it shuts down running programs, and exits normally) or it shuts down like if you cut of the power?

    your power supply may be failing. I had mine on 24/7 for 3 years and the PSU finally went tits up.

    I changed my power supply yesterday night and I am still having problem with it... Please advice. Also, my computer shuts off automatically and doesn't save any application that I am working while shuts off.

    Yeah, i have that exact same problem... i mean exact. I never shut off my computer, and now, all of a sudden, it cuts off after an hour or two.

    this will probably not do anything, but make sure that the power setting on the PC are not set up in such manner that the PC shuts of in some minuets.
