HELP
for the past two days my six month old msi laptop has been artifacting (pixels and patterns all over the screen and negative colours) then freezing then restarting. it started happening while playing full screen games, but it now happens at seemingly random times. i’ve already clean installed all nvidia software and underclocked my gpu, i’ve also deleted msi dragon centre ect.

specs:
MSI gt75vr titan
core i7-7700HQ
gtx 1080
16gb ram

any feedback/help would be greatly appreciated :)
