DVI No Signal or Screen Freezes when trying to play any game.

[Jagdpanther22]

First let me say that the computer works fine when not trying to play anything game-related. It can sit here at my desktop for weeks and be completely fine. The second I try to play any video game it leads to trouble. Also, Please read the whole post before answering just so you know what I've tried and the situation.
Thanks.

I bought this computer in October 2009 and it worked like a beauty. Then this issue started to occur around April 2010. I've tried a number of things now and I am completely at a loss as to what could be wrong. The issue that has been occurring is when I am in any game, no matter what game it is, after a completely random amount of time(could be 20 minutes - could be 5 hours) the monitor will display "DVI No Signal" and the amber light will appear on the monitor as if the computer has been shutdown OR the monitor will turn a solid color depending on what color was dominate during the time of the freeze. When this occurs I can sometimes still hear sound in the background from whatever was happening and I can still talk over the program Ventrilo to friends. Other times the sound will freeze completely and just loop and I cannot hear sound from the game or talk over the program Ventrilo. The only way to fix this issue and get the monitor to display anything again is to hold in the power button on the computer and shutdown the system and then restart it. After this is done the computer acts as if nothing is wrong. If the reset button is pressed then one beep and three short beeps comes from the motherboard. In the motherboard manual this claims that these beeps mean "No VGA detected". This doesn't make any sense because everything that has to do with the Video card has been replaced or swapped out.

So far I have tried:
* Replacing the Graphics Card
* Replacing the Motherboard
* Replacing the Power Supply
* Different Monitor
* Different DVI Cables from Card to Monitor
* Different Wall Outlets
* Different Power Cords for Tower and Monitor
* Updating drivers of the Graphics Card, updating the BIOS, updating Sound drivers
* I've probably tried other things but I can't think of them right now

The only few things inside the computer that haven't been replaced are the RAM(I've done multiple RAM tests with MemTest86 and nothing has been found), Hard Drive(Multiple CheckDisks have been run and it claims the Hard Drive is clean), Processor, and the CD Drive.

The EventViewer Application and System logs show nothing in them at the times of the crash, there's not any Errors or Warnings. There was an error entry about something to do with WMI every time my computer was turned on that someone else was having an issue with but after fixing this I'm still have issues.

I've also been looking up this issue on Google and it seems to be an extremely common issue that many people are experiencing but I cannot find an actual solution to this problem. Multiple people have listed solutions that have fixed their problem but none of them have worked for me. So I turn to multiple internet forums and discussion boards in hopes that someone else has experienced this problems and knows of a fix for it.

Games that I've experienced this problem with:
Minecraft
World of Warcraft
Starcraft 2
Mafia 2
Call of Duty 4: Modern Warfare
Call of Duty: Modern Warfare 2
Killing Floor
Left4Dead 1 & 2
Team Fortress 2
Many others

There might well have been but you've blown it by getting impatient and bumping your thread.

Don't...

* Post in ALL CAPS or use excessive punctuation!!!
* Share personal information, like your email address. Identify theft is real.
* Bump posts, claim "first!"
* Hijack a topic. Stick to the original conversation.
* Ask for help pirating, cracking passwords, or bypassing copyright protection
