A total waste of money. During the first three months, the laptop fan makes strange noises. I contacted the seller about the problem and he suggested a refund of $95 for repair coverage. At this time, I accepted the seller's suggestion believing that the local repair shop would fix the problem. During the first 3 months, another problem arose, the laptop stopped repeatedly (I have pictures of the laptop stuck and the error it shows). At first, I thought the problem was with the drivers that just need to be updated (this is what colleagues suggested to me). I updated the drivers and the problem is still there. A local repair store said that the laptop might have hardware issues with the Invidia card drawing or that the seller used an incompatible RAM or drive when performing the upgrade.I have contacted the seller but he does not want to help me and he refused to return the item due to the expiry of the return period.The laptop has been with me for 4 months and the two issues (strange fan noise and frequent laptop stops) appeared in the first 3 months
