My friend has a problem and neither of us can figure it out: When a driver for a graphics card (that had previously been used on the same computer) was installed, the computer froze mid-installation and the screen turned black. After a little bit, my friend took out the (PCI) video card and booted the computer using the integrated Intel graphics that came with the computer. The computer started up, everything worked like it should have. So, we though for sure it was a problem with this video card. We went and got a brand new card, and when the computer started up with the new card there was nothing but black. The same thing happens in all of the PCI slots as far as I'm aware of. Does anyone know what's going on? Is there a problem with the power supply? Feel free to ask questions, I know I didn't put much information up but I didn't know what would be needed.
