Hey! I have a weird issue. My Samsung 350V5C-S05CZ boots only sometimes. Like one of 10 times when I turn it on. Sometimes it boots 2times in a row and sometimes it doesn´t boot even after 20th time. When it doesn´t boot Leds turn on, fan is working, but screen remains black. It seems like sometimes the power on self test just diagnoses something wrong and notebook remains in this state (it is exactly like when you don´t have any RAM connected). I don´t think any hardware is damaged, when notebook boots it is working completely fine even for hours, booting is the only problem. I was thinking about updating BIOS, can it fix the issue? Is updating BIOS safe? Thanks for your replies!
