Ok, so my dads pc (its in sp) completely randomly locks up. Im not sure what the deal is. it was working fine, i swapped boards and it game me a memory error but no big deal, fixed that. now, it locks up a few times a day, whether it is in the bios, or post screen, windows, trying to format windows ect. Im not sure what to do! if its the board i'll rma it and give him "back" the P45 but if its ram or hdd idk... what do you suggest?
