I have just installed Windows 7 on one of my slightly older computers. It has 1.5GB of RAM and has a Pentium 4 CPU so its good there. However Windows 7 seems to be having troubles with the graphics cards, its a dual-monitor setup. Whenever i run certain applications (Windows Media Player, Nero, Quicktime) the computer crashes with the attached blue screen. I was able to fix this by completely disabling all hardware acceleration, but that made many programs run unacceptably slow.
Also Windows Aero won't work saying my drivers are not WDDM or something. I don't really want to buy a new graphics card as it's an old computer. I really would like Aero to work.
The computer is an Emachines T3958
From what i can tell the two video cards are
1. Integrated card - Intel 845GV
2. PCI card - Geforce FX 5200
