Re: XPS m1530 gaming problems
A faulty GPU will often cause the display to become scrambled or go black but it will not shut the system down. Your system is indeed overheating - plain and simple. If you don't get that fixed, you do risk severe internal damage to the system - and it's not covered by warranty. Start with a thorough cleanout of the heatsink assembly - just a thin layer of dust will cause the rapid overheating you're now seeing.
