I have a custom build with the following specs:
*Gigabyte EP45-D3P mobo
*9 Mb ram
*Intel Q9550 Core2 Quad 2.85 processor
*WD 1 Tb harddrive
*WD 750 GB harddrive
*SAPPHIRE HD 4870 1G GDDR5 PCI-E
*Kingwin Mach 1 800w modular ps
*HT|Omega Striker 7.1 soundcard
*Windows 7 Professional 64-bit o/s on 1TB hd
Just added 750GB hd to system for dual boot system with XP Pro 32-bit o/s (needed XP for older cad program). Everything worked great until I added drivers for video card in XP. Will not boot into XP, just goes to black screen and machine shuts off. Have tried every driver ATI and Sapphire has, but get same results. I have to boot up in safe mode and remove video drivers and system will boot into XP with generic driver. Windows 7 works fine with Sapphire drivers. Any idea on what could possibly cause conflict?
