I bought this m15 R3 for 4K 1 year/10 months ago. It worked really well for a year or so of use on games. Then suddenly it starts dipping to 35 FPS in games when it is usually at 120 FPS. This happens about 15 minutes after I open up any game. It is so frustrating paying so much for a laptop only for this to happen. Can anybody help or direct me to someone who can because I've been trying to fix this problem for so long but no matter how many hardware tests I've done it always says that it's fine.
