Okay , this problem is a bit hard to explain, basically after rebooting everything work perfectly, i usually oscillate between 4 or 5 hardware accelerated applications in my regular use of my computer: SecondLife, VideoLan, Eve Online, 3dsMax,... this problem is happening to me since a few weeks now, and i can't pinpoint what is causing it. Basically everything run fine, and after some time , (1 hour, 2 maybe) as i start a new 3D app, the image show some sort of graphical corruption of several types: -"badly tuned tv" looking noises on the screen (like lines and stuffs) - flickering of the 3D window - no display at all - application hang - display freeze usually when they happend i run dxdiag to see if it spot anything, sometimes the test cubes have texture corruption., and most of the time the 3D tests cannot initialise and return (D3DERR NOT_AVAILABLE) at this time the only way i found to fix the problem is to reboot. Needless to say i use the very latest drivers and the system is freshly reinstalled. i just ran my 4 memory sticks (one by one) trough memtest86, so aparently it isn't the ram, all the sticks are working and in perfect state. Any idea what can be wrong? system specs: OS: Windows 2003 server R2 CPU: Athlon X2 4200+ RAM: 4x1Gb ddr (pc3200 if i remember) MOBO: Asus A8N32SLI deluxe Graphic card: Geforce 7900GTX 512Mb Dual screen 40Gb IDE Hard disk 320Gb SATA Har disk
