I just installed a new power supply (350W), but the problem is still there
Besides the problem still being present, sometimes the game just crashes to the desktop all together as a result of an error in oblivion.exe
Further, after it crashes I cannot start the game again, the monitor just "clicks" a few times after turning black, and it returns to the desktop. Seems like some graphics thing crashes. Besides not being able to start Oblivion, the game Morrowind cannot be started either. It says "Render Creation Error" in an error box. I made a small screenshot....well
