I have a Asus Notebook G60 series laptop with an intel i7 processor and 6gb of RAM with a Geforce GTS 360M 1gb graphics card. I preface this whole discussion knowing that this laptop is getting old and it probably doesn't owe me anything.
This is actually the 3rd exact laptop i've had. The two previous laptops were replaced by Asus for free the first during the warranty period and the second after it because they both suffered the exact same issue. They had previously been sent back to asus for repairs and returned to me "fixed" although this was never true and they ended up replacing them after multiple attempts. Best guesses at the time was there was a graphics card issue but they weren't able to pin point it.
After getting each of these new laptops from them they have worked without issue for about a year or so. Over time they start to have random crashes generally when playing games and the frequency of this increases. With my current model I'm at the point where if I boot up a game it'll crash with 5 minutes or so. I am able to surf the internet and do other stuff in applications without issue. I can also leave the laptop running for multiple days without crashing. When it does crash the power abruptly goes off, no BSOD or other warning.
Although the laptop is getting old it's quite frustrating that I can't use my only gaming system for what it was intended. I also don't want to replace it since it works just fine for other things and just don't want to spend that money.
Any help and suggestions people could give would be great.
