Hi , ive gotten my laptop the Samsung Gamer 7 , 4 years ago. But this year it suddenly started crashing with a bzzzz sound. It happened like once a day , and then few times a day and now quite often. I sent it to samsung , they told me it might be the ram's problem (according to them it wasn't original) so they removed it and they informed me 80% of the time it's the ram's fault. But when i got home it still crashed with the bzzz sound. Thus they told me it's highly likely the mother board's fault which will cost me around $500. Should i repair or replace? The gamer 7 costed me around 2.5k. Should i take the risk to repair it? I'm pretty scared to repair as it might still have the problem after paying another 500 dollars. Any advice?
