Hello TomsHardware! I encountered this problem on my laptop (ASUS TUF503, i5-7300hq, 12gbram, Gtx1050, 5400 rpm hardrive), in which it suddenly went into blue screen and upon restarting, it will load for minutes and will directly go to BIOS and the hardrive is missing. What might causing this? Because in my knowledge, blue screen means RAM. Thanks!
