did you happen to play around with the timings of the ram?
I have an AMD 1700 o/c'd to run at the equivalent of P4 2.2
FSB and Voltage tweaks were great,, but when I set my Ram timing incorrectly,, my system would lock up ,,, first it would not boot at all,, then it was jittery,, then found the sweetspot, and all is well
Check your memory timings on the MB as well,, If your ram is lower grade,, your issue may lie there,,
Difficulty with this issue,, It points to MANY causes for the similar effect,,
good luck, Be Patient ,, knock one issue off at a time,,
