Game is constantly crashing

Hello, so last week a friend of mine got BLTPS, so yesterday we played together.
In like 5-6 hours, my game crashed like 4-5 times. Each time i had to cancel the process from the taskbar and load again.

It’s weird because a few months ago when i played ( i only played it solo then though ) it would crash like once per 20 hours ( super rarely, you’d forget there is an issue ).

I don’t know if the problem is because i am playing with other people, or maybe it’s because i am playing fullscreen windowed, or from a laptop, but i should report it i guess.

GPU - Nvidia GTX 880M 4 GB GDDR5
CPU - Intel i7-4700HQ 2.4/2.4
OS - Windows 7 ultimate 64 bit

All drivers are updated, i can run Borderlands 2 online, it does not crash, but BLTPS does.

I’m having the same issue. Not just with BLTPS but also with BL2. I can play for a random amount of time and then the game crashes.

I have run MemTest, Video Memory Stress Test, and PC Check and have not found any errors with the hardware.

I’ve monitored the GPU temp and it’s hovering around 60-70C while gaming.
