Can any 1 help i got a

3500 64-bit (939) winchester
a8v rev2 deluxe mobo bios 1007
512 corsair pro ram
xfx gefroce 6800 gt 256mb
480 enermax psu


all sounds fine but when i first purchsed it i couldent get the computer to boot
so i took it to the shop and they said i would need a bios update so they done all that the other problem then was i
could only use my corsair pro ram in the third slot on my board any other slot and the computer would not boot.

any help on the matter the shop told my to get cruical ram so thats what im going to do next
but i would like to no if any 1 else has had this problem or no how to fix it.

every thing works fine so it must be ram issues
but it does say that u will need a bios update to get a winchester core to run on an a8v mobo
and that should also solve the ram problem but it doesent.
