I have a cheapo HP stock laptop that I am using just while traveling, and whenever I activate hardware acceleration on any of my browsers, the entire display randomly flickers violently (not just the browser). This started happening a year after buying the laptop. I checked various things software-wise but could not find anything, so now I want to see if the video circuitry is failing. I also see on the Internet that if the task manager is also flashing when loaded (which it does), then it is a hardware problem and not a software problem. I have an extended warranty, so i would like to prove that chip is the problem if indeed it is, before talking to support or I waste my time sending it in for replacement.
So, not sure this is the right program to use, but in any event I don't want to damage the laptop with the test as I really need it at the moment, so what would be the best settings and test to run? Also, what is a safe maximum gpu temperature(s) at which point I would need to stop the program?
