As some of the other guys have said maybe try a better PSU, less RAM - a cheap PSU will not handle the job of any sort of OverClocking as they just don't have the electronics or technology to do so...
ok here goes .. these are the settings ive been trying.
cpu bus freq - 286 (think i was wanting to much here)
cpu ratio - x14
dram freg - 1525mhz
cpu/nb freq - auto
ht link - auto
cpu volatge - 1.45v also tryd 1.5v
dram voltage 1.65v
cpu load line - auto
cpu/nb load line - auto
thanks again everyone for your help
