So I installed XP 64 bits.
When I installed warcraft III and when I alt tab my screen turns black but the system is still running.
Everything is fine except that the monitor turns black and i have no clue how to fix it other then switching the connector to the other 260 after shutting the computer.

So apparently if I shutdown my computer and I restart it; it will load the OS but then the screen will black out again.
The only way I found that will temporary fix this is taking off the power and replugging the monitor back onto the graphics card. But then again if i want to alt-tab in games anyhow the screen will turn black again. Is it a driver issue?

I even installed the driver that came with the 260's.

Is it my graphic card? Or is it something else?
It's been bugging me.

More info: I am running on 8gb/12gb ddr because I still haven't re-adjust the power output on the ram slots.

  1. No don't do that. Vista is pretty well built. I run into blank screen while gaming or switching back from gaming from time to time. Just press CTRL ALT DEL & select task mgr, then right-click kill the offending program/process in memory. Works every time.

    I also made a few keyboard shortcuts to shut down, abort shutdown & kill explorer in the event I need them.

    Update vista, drivers & games. If no luck, run 3dmark in a loop for 5-8 hours:

    Click change under settings tab, set loop to 10-infinity.
