Hardware Failure Error

What happened? I was playing Guild Wars 2 and this page suddenly popped up!

Guild Wars 2 detected that your computer is experiencing a hardware malfunction and opened up this page to help you identify and resolve the problem.

 

How did Guild Wars 2 detect the problem?

Guild Wars 2 conducts system tests while you’re playing the game to verify that your computer is operating properly. When Guild Wars 2 runs, it continually tests your computer by performing a set of common mathematical operations, such as addition and multiplication, and then checks the results against a table of correct answers. When the game detects an incorrect answer, that answer may reveal a problem with your computer's processor or memory.

 

Why does it happen?

We've worked very hard to optimize Guild Wars 2 to take advantage of modern hardware and to bring you the best performance possible while offering a fantastic gaming experience. Because Guild Wars 2 is well-optimized, it's capable of delivering amazing graphics, but those graphics require the computer to work much harder than it would in other circumstances.

 

In particular, modern video cards use more power and, consequently, run hotter than ever before. When computers run too near their power and heat limits, they tend to make mistakes. Problems that wouldn't occur while running low-intensity tasks like reading email or browsing the Web are much more likely to occur when running an application that's trying to squeeze the maximum performance out of the hardware.

 

What types of problems occur and how do I fix them?

Hardware problems fall into several categories. Here are some things that may help solve the problem you're experiencing:

 

Memory Failure: Even though your computer may appear to run normally most of the time, it is possible that your computer's memory may be damaged or defective. We recommend running Prime95, an open source program available here (choose the download appropriate to your operating system). This program is capable of rigorously testing computers that appear functional even though they are damaged.

 

Over-clocked Processor: Some computer owners adjust the clock rate of the processor, making it possible to perform tasks more rapidly. While your computer might seem stable during routine operations, it could  fail while running more processor-intensive applications such as Guild Wars 2. If you'd like to test the stability of an over-clocked computer, try running Prime95 overnight. an open source program available here (choose the download appropriate to your operating system).

 

Overheating: If your computer is too hot, it can generate odd results. Verify that all of your computer's cooling fans are working and that it is operating in a reasonably cool environment. Sometimes just blowing the dust out of the vents is enough to correct overheating problems. However, if you have a high-powered video card, you may need to add additional fans to your computer case.

 

Underpowered power supply: Today's high-end video cards often require you to boost the power supply in order to prevent problems. Check your video card manufacturer's power requirements to determine whether your card, coupled with the other components in your computer, requires an upgrade to your power supply.

 

If you're sure that none of these situations apply, please call your computer manufacturer and request their help in solving the problem.
