Hi All,

Well after some testing overnight, it was still locking up, and this isnt even in the operating system yet. That much I can establish, by running memtest86....what an awesome utility.

Anyways, this morning I did something that has so far given me good result, I increased the voltage of the ddr2 ram one notch, by going into the bios you should have this option.
typically when running memtest86, it went to only two passes at the most, so far for last hour its gone to 4 and the test is still running, I.E NO LOCKUPS, I have still left it at 2gighz setting on the cpu, so people it could well be there is just not enough juice supplied to the memory chip.

Best to findout through by running this program, whether it's your operating system at fault or the memory.
so far so good.....
