Lately I have been experiencing some issues with my laptop (acer predator helios 300). Couple of days ago games started crashing while plugged in, working fine on battery. Sometimes games just exit, sometimes give BSODs (three types so far: DPS watchdog violation, video scheduler internal error, page fault in nonpaged area). Laptop is working fine if intel HD gpu is used, but when using nvidia it either crashes the app or gets BSOD. I bought the laptop 4 months ago, but I don't really want to send it to repairs, so my question is: is there a way to find out whether it is hardware of software issue? Crashes started out of nowhere, no physical damage prior to issue, no voltage surge, nothing. I opened up the laptop and inspected elements, no burn marks and no burn smell whatsoever.
Any advice would be greatly appreciated!
