) and then will show a black screen or just reboot....is this my poor barton cannot handle 2.5ghz with 11.5x and 220mhz fsb with 1.85V or my psu is undervolting? also sometimes it just reboots? hope it helps?

I would say your psu is the problem, it is the most important part of your system. Think of it like this, the electricity the psu supplies to the system is like the blood in your body, not enough juice in your system it shuts down, not enough blood in your body it shuts down. I would get a good quality 'branded' PSU with at least 24 - 26 amps on the 12v rail.

VCore of 1.85V !!!! I'm no expert in Athlon XP's, but isn't that a bit on the insane side?

I would say that if your system wasn't overclocked you'd probably be alright... but since you are you may want to get a better psu.

how many amps does your current psu have on the 12v rail?
