I'm currently building a new computer and there is a major problem with it. Basically, whenever I turn on the computer and at the bios/memory testing screen there would always be errors such as wierd characters or just stop after detecting the cpu or checking the memory in a loop and never stop. After I replace the new memory using my old memory, the new computer got pass the bios screen. However, right after this I ran memtest and the computer always randomly turn off after like 15 seconds. Can it possibly be my motherboard? Thank you in advance.
