My computer shutsdown when I try to play PC games?

 For some reason whenever I play a computer game, my computer automatically restarts itself. Either before the game starts or after I close the game. This has done this to me with Company of Heroes Online (this game doesn't work on my computer anymore anyway, but when I started it), Aliens vs Predator Classic 2000 (when I started it), and now MechWarrior 3 (when I closed it). However I tried playing AvP Classic 2000 again and it worked. I don't know why it does this, I have all of my drivers and everything, so why does my computer automatically just instantly turn off and then turn back on? After it turns back on it says that Windows XP has a serious problem and asks me to send an error report, apparently the problem lies somewhere with these two files or something:

C:\DOCUME~1\Kevin\LOCALS~1\Temp\WERab4b.dir00\Mini011111-01.dmp
C:\DOCUME~1\Kevin\LOCALS~1\Temp\WERab4b.dir00\sysdata.xml

It just sounds like you need a new computer all around. The one you currently have can't handle modern games. Can you share your computer specs?

What operating system?  Sounds like your windows is broke

Are you low on HD?  Might want to run some memory checker to see if you have a faulty dimm (http://www.memtest.org for example)

Those two files you posted are dump files I believe, as in your computer has written the info of the error to those files. My suggestion is you take this to a forum or site that is actually dedicated to computer issues, they can look at those files for you. If I had to guess, though, this could be a hardware problem, since you said it only happens with games, and this is a very strange behavior.
 
Most importantly,does your screen turn blue beforehand? If you're getting a blue screen error I'd be willing to bet its memory related. But then again, I have no idea how windows works.
 
Also, virus scan, fix registry errors, etc. Google will help you find tools to do this. Really, though, if you're still running XP you may be ready for an upgrade.

Delete C:/Windows/System32 ..... works every time.

With Windows there is only one solution. Format and Reinstall. Don't bother troubleshooting, there are very few ways to fix a fucked windows install.

Sounds like an overheating problem or voltage problem to me.  Cleaning the inside of your computer, checking if all your fans are still spinning could be a cheap and easy solution.

Overheating probably doesn't happen before a game has even started though. "

You see where it tells you it wrote those files? 
 Mini011111-01.dmp and the other one?  That info will tell you what caused the memory dump (a memory dump is when it writes the memory into a file and saves it as a .dmp file). Those files were created as a result of the crash, and were not the cause of it. You'll need something like windbg to open the dump file.

Sounds like you've got a problem, guy.

I have a similar problem dude. I am planning my reformatting process which I guess is my only answer.

Where would he be without you? "

Sounds like either an overheating problem or a Power Supply problem.  used to happen to me.  Maybe you need to install a couple of fans an d clean the dust out of your computer.  Maybe you have to install a bigger power supply if you've installed graphics cards / hard drives and the like to your computer.  

Sometimes a computer will shut down if the psu isn't giving enough power to the videocard. I hope you don't have some 350 watt power supply. Then again who knows for sure until you actually start isolating the problem by testing other psus and stuff like that.
