Is My Video Card Overheating?
Other than specific things that you might encounter from using 3d accelerated applications such as video editing and gaming, there really isn't any way of indicating that your video card is overheating. In short, if you're not using any video intensive applications on your system, it can be near impossible to determine whether your graphics card is overheating. Fortunately for you, there's a solution to this problem.
To begin with, go online and download and install a program called Everest. You may find that all the versions of this software are commercial, but if you do a thorough search on Google it is possible to find the freeware version.
Once you have this program installed onto your computer, your next task is to click on the tab for temperature; this process is fairly self-explanatory; so you shouldn't have much difficultly here. Once you've done this, then you'll need to locate your video card.
There is a problem to this however.
How do you determine whether or not your graphics card is overheating? Graphics cards have wildly varying temperatures, so there's no average temperature that you can use to determine whether or not its overheating. However, the answer to this problem is fairly simple:
Create a thread on a computer forum like Toms Hardware about your current video card; ask the forumers what temperature your card should be running at. The response you get might vary from individual to individual, but you should monitor the current temperatures your getting on your video card to see whether it's unusually high compared to your responses, if it is, then you know you card has a heat problem.
