I have an Asus Q502LA laptop, about a month and a half ago it crashed and would only go to the bios menu. I took it to Geek Squad to get it fixed, they said they replaced the hard drive but i had the same problem a few hours later. After taking it back a second time, they said they replaced the motherboard and the hard drive again, but a few hours later it crashed again and got stuck on the bios menu again. Any ideas on what else could be the problem?
