I am currently experiencing a problem where my system will lockup in most (if not all) 3D games that I play.
I first encountered the problem several days after finishing an upgrade to my system. (Most of the key components are new.) After getting the system setup, I was able to play Sim City 4 (a hardware accelerated game) for at least 2 days in a row. However, one day, after playing the game for around 2 hours or more, I encountered the first lockup.
What is interested about the situation, is that I had been playing SC4 for around 2 hours or so, and I then exited the game and did some other things. As far as I can rememeber, I made 0 changes to the system. It was when I started the game up again, that the computer locked up within about a minute's time. I was still able to see the game on the monitor, however the cursor would not move, the sound stopped playing, and the keyboard lights would not change when I pressed the caps lock key.
After this incident occurred, I basically found that almost all of the 3D games that I tried would lock up in the same way (many times within a few seconds). During this whole time I never received a blue screen error.
Over the past week or so, I have tried several different things. I was even able to play a 3D game demo without any lockups at one point (not sure about now though).
*) I went into the video card properties and turned off things like the anti-aliasing and anisotropic filtering -- Sim City 4 still locked up.
*) I ran Sim City 4 in software mode. I does not lock up in software mode, but does lockup in hardware mode.
*) I lowered the video acceleration. Basically if I raise it above the 4th level (enable Direct3D) then I will get lockups in Sim City 4 hardware mode.
There was also an interesting problem that I encountered during this time. Occassionally, insted of locking up during a 3d game, my surge protector's circuit breaker would flip it's switch, thus causing me to lose power to the system. Sometimes after powering up the system after a lockup or "power loss," the surge protector's circuite breaker would even flip after a few minutes of basic desktop useage (no 3d games). If I switched to a different surge protector, I did not lose power, however the lock ups continuted. Towards the end of my testing, it almost seemed as though the surge protector that kept losing power was becoming less prone to the lockups. Because of this odd situation, I was wondering if perhaps the power supply or video card may be causing some unsual surge.
