Comp not booting up

[MitaDC]

Hey I just switched HSF's on the comp that i am building and I went to turn it on and it ran for about 3 sec with fans and everything running and then it shut down....do you guys have any ideas what it could be??

2500xp Barton
512mb Ram
Chaintech 7-NJS
9500 128mb Graphics card
I switched a Zalman hsf with volcano 11+

I was thinking maybe I was sucking up too much power but I have a 500watt psu. Also it sometimes will boot only for like .25 sec and shut down then if i flip the switch on the back of psu off then back on it will do the same thing. Same thing happens if I unplug it. TY

Well, how many deevices using the 12V rail? It really doesn't matter how much power your PSU has. What matters is how much it can supply to your 12V rail.

One way to find out would be to disconnect devices that use the 12V rail such as HDD, CDROM, CDRW, DVD, additional fans, etc..

Try booting with just the hard disk and the CPU fan running from the list I mentioned above and I think that may give you the answer as to if the problem is due to the PSU..

I have let me see...... 6 case fans, HDD, CD-RW, Front LCD panel takes 2, Video card takes one, CPU takes one, UV light takes one so all together......13 :0)

I will go try disconnecting all of that....took me forever to do though :0( I will post back in a sec

Ok well the Volcano 11+ comes with a thermal probe and I pulled that out and the problem went away. TY for the help NDC
