sounds like a dodgy ps3, not had any problems with mine which is nearly 7 years old, played gta v and black ops 2 all the way through and never seen any crashes
Yeah, same here - and I've really pushed my PS3 to the limit sometimes, like with many hours battering games in full stereoscopic 3D (turned all the way up to its maximum setting), and occasionally playing constantly until the fan in the poor thing was sounding like it was about to take off... but I can't recall many actual crashes, if any.
Sounds more like something might've gone slightly kaput inside that one, unlucky. I've had a few issues with the dualshock 3 controllers, but generally the console itself has been rock solid - and considering how it coped with graphically-amazing games like TLOU and GTA V released some 7 years after its birth, I don't think build quality has been a big issue this past gen. Guess they've all gotta go sometime, though.
