My office workstation machine has lately been "losing" the graphics card EVERY time I reboot the machine.
It's a Dell Precision 490 with dual dual-core Xeon 2.67 GHz CPU's, 4 GB DDR2 memory, and an nVIDIA Quadro FX550 128MB graphics card. The machine is nearly 3 years old. I have two 19" 1280x1024 LCD panels hooked up via DVI to the graphics card, with the Windows desktop stretched across both displays to 2560x1024.
In recent weeks, every time I reboot the machine, the desktop comes up at 1280x1024, cloned on each display. When I look in Hardware Manager, there's a yellow exclamation mark next to the graphics card, and it says it could not start or some such thing. There is also no nVIDIA Options choice when I right-click on the desktop.
So every time this happens, I end up re-installing the nVIDIA driver (latest version), restarting, and then it seems fine. But then the next time I reboot, I'll have the same problem again.
What could be causing such a thing?
