Hey Guys, thanks for reading. One of my laptop boots if I use a 1gb ram stick, but wont boot if I use the original 2x8 gb sticks it came with, even though both 8gb sticks work fine in other laptops, wont boot if I use a 4gb ram stick even though that stick is fine too. I should add I was able to boot once with 4gb stick before I tried the 1gb stick, but ever since I tried the 1gb stick it wont work with 4gb either. The computer goes on no logo no bios only black screen and the power light, I can hear the fan. Any help would be greatly appreciated.
