Recently I had a new motherboard installed to replace my old one that overheated. The new motherboard is a MSI H55M-E23 that has an Intel core i5 650 chipset installed. After getting all the drivers to work, I then installed my old XFX Geforce 9500 gt (512mb gddr3) in the pci-e x16 slot. When I went to turn my pc back on it wouldn't boot. I then removed the graphics card from it's slot and it booted up just fine. The same thing happened with my DIAMOND XtremeSound 5.1/16 bit Sound Card when I put it in the PCI slot. They worked just fine in my old motherboard only 4 weeks ago so I'm not sure what the problem may be. Is is a driver I'm missing for my motherboard or some type of BIOS or maybe a hardware error?
