I cant find the PCI controller drivers and the Video Controller drivers. My netbook is Acer Aspire D257.

Hello Philip, Well, adding an Internal PCI would be just about imposable. And also the last time I checked no one manufactures an external pci slot. Im sorry,

Have you tried a System Restore/Recovery? Can you boot to safe mode? Try the restore/Recovery procedure: Shut down, unplug, remove battery, plug in, push the on button and When Acer splash is on screen hold Alt and keep pressing F10...

I've encountered a situation on my acer aspire 3680 where in Windows 8 Prerelease, I had to download and install the proper video driver from the acer.com website to allow it to have full resolution. Maybe try this for the Bluetooth and video controller problem, if you can even see the screen in windows 7.

i don't have drivers for my aspire one d257 for video controllers, pci ,& network controllers
