Cold boot problem.

I recently face a wierd cold boot problem on an old computer of mine. It is a Athlon xp 2500 with stock heatsink with a Soyo Dragon plus motherboard and a Thremtake power supply. Recently when I turn on the pc it sometime won't boot but there is power and I need to turn off the power supply before it can boot into window. What seems to be the problem
 
If the Tt PSU is > 3 years old it *might* have dried out capacitors and needs one or two kicks in the butt to boot the rig.
Each time the power button is hit the PSU tries and that warms the caps just a tad. You could warm the PSU internals with a hair dryer before powering up. If that cures it, it is dried out caps.


Put the comp in stand-by over night and see if it boots first try. Just being in stand-by will keep the PSU warm.
I had one that did just as your's is doing. New PSU time, I guess.
Look over the MB caps real good while you're at it http://www.badcaps.net/Ident/
 
Startup time for a PSU is very hard as it's overcoming the inertia of stationary HDD platters.

If your PSU is dying, it will often reveal itself upon a cold boot.
 
The PSU is the most likely culprit but if that turns out not to be it, the next most likely is a similar cap-problem on the motherboard or you might have added somthing to the circuit the PC is plugged into & its just not getting enough power to start.
 
Soo. what are my choice? the psu is indeed 2-3 years old, heavy usage for 2 years( rarely turn off) before I hand the system to my parent, where it got somewhat low usage but they turn it on and off several time a day. And the cold boot problem doesn't happen everytime, just once a while. I have on my hand a raidmax 400 watt psu, should i put it in as time bomb since radimax one pretty much suck bad or just get one of those ultra far psu next time they are on sale? If it is mobo... i see no point of trying to fix it since socket A is antique and it is not worth it to replace the mobo.
 
You can try just cleaning the inside of the PSU and maybe clear all those "Ghost load" created by the dust build up. If problem persists try the Raidmax.
