Computer randomly shuts down when playing games

    Hi, my computer randomly shuts down when playing games. The inside of the computer is clean and I really don't know what could be wrong. Maybe a power issue or my crappy case? I've checked through similar threads and I can't find any solutions that helped. Any help would be greatly appreciated. Here are my specs

    OS: Windows 7 Professional
    MB: Gigabyte
    CPU: AMD Athlon 64 X2 6400+ Dual Core 3.2GHz
    GPU: nVidia Geforce GTX 285 BFG OCX
    RAM: 4GB
    PSU: Alpha Power 450w Power Supply Unit ATX
    Case: EZ Cool

    Are your drivers upto date, mainly the graphics card? also check Device Manager for any yellow ! marks.

    Does this only happen when playing games or has the random shutdown happened when using other applications?

    It could well be your PSU is a little underpower for all the hardware you have connected, as even USB devices can draw power

    What are your system temps and you can use Speedfan to let us know these as random shutdowns can be where the temp of motherboard , CPU and GPU hit a high.

    In Event Viewer at the exact time of a shutdown are there any error warnings, likely in System or Application logs, if so paste them into a notepad file and attach to your next post as per HOW TO: Attach Items To Your Post [/QUOTE]

    I would agree with the power supply diagnosis mentioned above. IMO, even a high quality 450w power supply is much too weak for a GTX285 and A64X2 6400+, and "AlphaPower" is not even close to a high quality unit, and is probably not capable of delivering a steady 450w of power, it probably has a peak output of closer to 375w on all rails combined (the 5v, the 3.3v, and the 12v), which likely means you have less than 250w of power available on the 12v rail which is BY FAR the most important voltage. A quality 550w or 650w would most likely fix the problem (it's better to have more wattage than you need for many reasons: you don't EVER want to run your PSU at 100% max for any amount of time, PSUs are most efficient at a 40%-65% load level, etc). With power supplies (and PC components in general, but especially with power supplies) you get what you pay for. A 550w unit from Antec or Enermax or ThermalTake will completely destroy a 650w unit from AthenaTech or RaidMax or iMicro or DiabloTek or CoolMax or EchoStar or Deer or BesTec or.... the number of makers of :crap power supplies is huge, but the list of quality PSU makers is much shorter: the 3 I mentioned plus most CoolerMaster units, all Seasonic, all Corsair. These are great brands. A 1000w low end unit will cost less than a quality 600w unit, and there's a reason: the cheepo 1000w unit is likely a 450w unit with a 1000w sticker. No joke. There is no real "standard" when it comes to labeling power supplies, especially in Taiwan and China. If you'd like some actual makes and models recommended, let us know. A great source for all things power supply, check out www.jonnyguru.com. IMO, they are the last word when it comes to power supplies.

    (no offense is intended with my above comments about the "AlphaPower" unit - it's surprising how many people have no problems spending $150 or more on a motherboard, $300 on a video card, $250 on a CPU, but scoff at paying $100 or more for a power supply; IMO, the power is the MOST IMPORTANT COMPONENT in a computer; without it, you have an expensive neat-looking box that sits there and does nothing, and a low quality unit will -at best- shut off when stressed slightly, or because of its lack of ripple control, it sends 'dirty' current thru all your expensive components, slowly burning them up from the inside-out, or -at worst- will burst into flame and destroy your precious graphics card, motherboard, and CPU in the process; I've seen it happen)

    Right click 'My Computer' and give us the CPU info at least and try a different program like Speccy as your list is inadequate, gives almost no info and what it does give is mostly useless. Your PSU volts are a bit low.

    EDIT: Whoa spaceoid, you really should start a new thread and not piggyback on top of someone else's. One problem is hardly the same as someone else's.;)
