Faulty Power Supply?

Hi, over the past 3 months, I've been having computer issues with my old gateway. These issues include a graphics card not working and when its in the computer, the computer seems to rev on startup, the computer suddenly turning off when logging on or on strenuous applications, and finally no post beep. This really sounds like a power supply gone bad to me (the psu brand is also thermaltake, which ive heard bad reviews). I'd really like a second opinion before going to buy a new power supply, or I'd like to hear if anyone else has had similar issues. Any help would be great!

  1. Well the power supply sound like it could be okay, but could be bad. A common fault of no POST beep is the ram, if you have another stick, try that. Also, it could be the CPU or even the motherboard.

    But it's most likely the ram or power supply, i recommend buying a new power supply and/or ram.

    People say it's bad to have a cheap PSU, but this one has lasted me over 2 years without a single hiccup and i have

    Core 2 duo 3GHz
    4GB DDR2 Ram
    Nvidia 9400gt
    500GB Hard Drive
    Windows xp

    Hope this helps

    This could be a number of issues...overheating, power, drivers, GPU, RAM all come to mind. What are your system specs? Have you checked your Event Log to see what errors are associated with the shutdown/reboots? Have you tried monitoring temps and voltages using an app from your mobo mfr?
