    Ok lately anytime I load any 3d intensive software my pc reboots with no error. Nothing in event viewer, I have the auto. restart unchecked but nothing. I just installed asus probe and the first thing that beeps is the +12v and thats reading 13.504v and also the +3.3v is showing 2.896v. My cpu temp is 50c and mobo is 28c.
    The power supply is only about 6-7 monthes old. It is a 420watt which was upgraded from a 250 watter. Is my psu a piece of $hit or what?

    hmmm... it is a possibility - what make is it? cos some cheaper ones dont kick out as much power as they claim.

    Model: OKIA-420ATX I am assuming this is a cheapo. What do you think about those readings? What can I do to determine if it is in fact the psu causing this? Thanks

    If you have a friend that has a comparably rated power supply, ask him or her if you can borrow it for a while so that you can see if it does the same thing. If it solves the problem, then the problem is the power supply.

    I had a similar issue and found that upgrading the PSu did the trick. Be careful with some of the cheaper models as they rate the unit by it's peak Wattage as opposed to average. I settled on a Thermaltake 480W PSu which peaks at 550W and have had no issues at all since it's purchase.

    Well none of my buddys have anything close to what I have so thats out of the ? It was kinda wierd, about an hour ago I was browsing online and all of a sudden the pc reboots but it did like a double reboot. It's like the psu shut off went back on and then shut off again in a matter of 2-3 seconds and I was'nt running any intensive software. I'm confused. Any other suggestions? Oh another thing nothing is overclocked.

    Could be the video card. My video card did that and it was defective... Try switching with a new video card see if that does the trick.

    Hmm, are you using a Dial Up modem, when i had a gateway computer several years ago, the modem would suck up enough juice(wether it was dialing or transferring info) to cause the computer to reboot. Also download aida32 and check all rails. I reccomend you check to see if all the screws in the PSU are in snug, but not to the point of stripping out causing a connection somewhere could fry out everything or ground out the power before it does any good(thus maybe a reboot?). If you have an older computer you could try out the PSU in that, or maybe buy a cheap 300 watt or so and if it works you found your problem if it doesnt work then its not your PSU.

    IMHO, If those volt readings are accurate, then they are both outside of the ATX spec. I'd get a decent PSU if I were you.

    Well those reading's were wrong come to find out. My reading's are ok but it is the psu because I unplugged a couple things in my case and the problem was gone. I got really cool looking case with a crappy psu so now I will be looking at antec etc....:)
    Thanks for the help!!
