    And sometimes won't turn back on for a while. At first I thought there might be a short in one of the connections inside, or maybe a dieing power supply. Those might still be true, but I remembered that this started after I told my computer to "sleep" after 3 hours. That is when it began randomly crashing. I've already turned off sleep, but the problem persists.

    My computer will just randomly die. Sometimes when I hit the power button after this happens it turns on for a second, fans spin, lights come on, but it dies again before it even gets to the bios. Every time it has died it has been when it wasn't in use (i.e., when it was at its lowest level of power consumption). Games play fine. All my drivers are up to date that I know of.

    Any ideas? I don't want to take apart my computer if this is a bug in windows.

    You can try to perform system restore to that date on which it was running good and remember perform system restore from Safe mode

    I don't have any restore points from safe mode, but I'll try on of the ones from before when next it fails. Any other ideas I can try?

    Sounds like a classic dying or inadequate power supply and supplies in cases, are seldom worth using.

    Hi Rich-M could well be correct can you take the side off and see if you can spot the label with the wattage anything under 550w will most likely be under powered a 550w or better would be best,also stock heatsink and fan are not always so good my son had a problem similar to this and a change of h&f solved it,have you checked in C\windows\minindump to see if any dmp files have been made or in eventviewer where you can look through the logs to see if ther is anything recorded around the time of these events

    The wattage is 500 and it has run the system for 2 years without issue.
    Eventviewer only shows inproper shutdowns with no indication of what caused it.
    Temps are all fine as well for what it is worth.
    Occasionally there is a bit of stuttering when starting up or in video games that is a fairly recent development. I suppose that would lend credence to a faulty psu

    Apevia are junk psu's so whether or not it did work, it was inadequate and could easily have degraded.

    HI ok all psu makers are allowed to work within a tolerance 20% which means a good make will output around 400 to 450w, if as Rich-M says the psu in your machine is not of that quality you will not get more than 400w so consider yourself one of the lucky few for it to have lasted this long,I take it you found no minidumps either which makes me think we are on the right track
