Ok, well then here we go.
First, we really need to know what you have and how the unit is set up. There is a free utility that will do this. Second, we need to know how hot the unit is running as you are using it, and there is a free utility for that.
> Go Here and download the free utility, Speccy, which is a system analyzer, and save to your desktop. You do not need to install it, it runs from the executable file. Click on it, allow a few seconds for it to finish. Then click File\Publish Snapshot. Click Yes, then Copy to Clipboard. In your next post add the link so we can take a look at what you have. Added suggestion: since this scan will also post what temperature your CPU is running at the time of the scan, let your computer run a while, open up your programs, game, etc. what you normally do when it crashes. Then do the scan.
>Go Here and download the free utility, Open Hardware. Click the gray "Download Open Hardware Monitor 0.6.0 Beta" button. Install it and leave a link on your desktop. When you are running your computer leave it open and diminish it. Occasionally open it and check what temperature your CPU is running at, then diminish it again. Doing this you will get a good idea of how hot your computer is actually running over a period of time. I have attached a screenshot of the item we are interested in (the red arrow). Let us know.
The reason for all of this is that crashes can be caused by many things, not just overheating. We are checking as many as we can to make sure that is actually the problem.
If it turns out that overheating is the problem, you may think about investing in a cooling tray which blows additional air in the air intake vents to keep the unit cooler. Here are a couple of links:
With Newegg you get 30 days, if you are not happy you can return it. If you call their 800 number usually they will e-mail you a prepaid shipping label with no restocking fee.
