Game Crashing/Issues PLEASE READ/HELP

So, I posted this awhile back, and got zero responses. Not even a go F yourself. Lol. So here we go again. Since my last post I bought a laptop as well. The laptop is the ASUS G752VL. It has a GTX965M graphics card, running WIN10 Home. My desktop has the GTX980 and runs WIN10 Pro. Both of them will run L2 for a little while. Sometimes 5 min, or less, and other times for a few hours. Then (on the PC) the whole system freezes and I have to hit the reset button. However on the laptop, the game client closes, or it disconnects. No GG errors or anything. No crash reports. I'm getting super frustrated that I can't play my favorite game. (By the way both PC/Laptop run 64bit which has said forever that it isn't officially supported) I've never had a problem until a few months ago. I'm thinking maybe a video or PhysX update? Or maybe a Windows update?? Is anyone else having this issue? I've checked temps and all are low-medium at max. Video temps are 50-60C, CPU is 30-40C. PC is watercooled, so heat isn't an issue. Even the laptop is running similar temps. 57C video, and 65C CPU on the laptop. I can't even afk overnight to fish, or sell in town. I really hope someone has some suggestions, or staff/moderator can suggest something.

Please help!!
