Overclocked CPU, no POST at next startup

[JayrollLim]

I overclocked my Athlon II X2 250 and now my PC wont boot the next time I shut it down and start it up again. I increased the FSB to 240 and the multiplier to 15x, and everything else is default. I feel something is limiting me from overclocking this processor, because when I restart it boots, but when I shut it down and start it up again I get no display...so I have to hit my reset button just to see an "overclocking failed" message. And when that moment comes, I have to load BIOS defaults just for my pc to boot again. Help me guys, I desperately need to overclock this to 3.6GHz. Thanks.

(When I overclocked to 3.6, no problems showed up on Orthos, Prime 95 and MemTest)

SPECS:

Athlon II X2 250
M4N68TM LE V2
FSP HEXA 500w
GeForce 7025
700GB WD GREEN

if you ran DDR3 1333 (3:10) RAM drop to 10600 (3:8). it will hep for boot , if you already do that relax timming latency and raise voltage ram by little don't too much
