My current PSU is a Antec True Power Modular 500watt

Now for the problem. MY computer will power up then right back down, then up, then down, then up, then down, then it will finally come on. Once its on its on. I was thinking mobo but a friend said prolly psu. Im waiting till thursday to get a 600 watt ultra just to test.

One minor detail I would like to add is that if I move my computer from lets say a lan back to my house, I have to reset the CMOS before it will ever power on again.
 
i had a similar problem back when i was first doing building my system, it does sound like a power issue how many amps are on the 12V rails?
i know that was my problem. melted 3 PSU before i figured that one out.but the CMOS thing makes me think possibly that your mobo just doesnt like that brand of PSU, one of the 3 i had just refused to play nice with my old ASUS board, and ended up frying itself.
so likely hood of PSU 75%
bad mobo 25%.

Most likely the power supply. I'm not sure about the true power gen1, but i know tp2.0's and smart power 2.0's were known for failure which usually started with similar problems, and ultimately would just stop turning on all together. Since you're getting a different psu on thursday, test your system that, and when you find the psu is discovered to be the problem, rma it to antec.

And Doc.. the tp500 has more than plenty +12V Amperage to power his system.. I'm not sure I want to know what brands you were buying if you "melted" 3 psus.

Edit: On your link you linked to a smart power 2.0. SP2.0-500 != TP Gen1. If this is the psu you actually have than there's a 99% chance it's the problem and you should prepare for a rma.
 
Yes sir it is the one I actually have. I did RMA it once before, so its not gonna be a huge shock to me. I will prolly RMA then keep it as a spare. But I think im gonna go with maybe a corsair,ocz, or thermaltake this time around.
