I recently upgraded my BSODing no good Vista Home Premium x64 to Windows 7 Home Premium x64 after receiving it from the upgrade option program. Well, it's been working a lot better than Windows Vista --but! All 3D applications (Games,3D modeling, etc.) using either OpenGL or DirectX regardless of Windowed or Full Screen cause a black screen if the game is closed. I have installed the latest firmware for my ATI Radeon HD 4870 X2 from the official ATI site which supposedly would fix some bugs in Windows 7, but alas the problem persists.
Once a program has been closed, the screen becomes black and I loose control of the computer. Even Ctrl+Alt+Delete refuses to work, resulting in an unclean shutdown (Me hitting the power button) in order to unlock it.
So, does anyone else have this problem or have some suggestions on how to fix/troubleshoot the issue?
Keep in mind:
a.This has never happened on Vista
b. A similar problem occurred on Ubuntu but was resolved via the new ATI firmware.
This may mean I should file a bug report with ATI, but if others are having this issue with nvidia we may have a Windows 7 issue here. LMK, thanks!
