Basically just made a new PC ASUS P5LP-LE X1300 PCI-E 2GB 533MHz Win Xp Pro SP3 all worked amazingly. uninstalled video drivers. windows did some updates before it shut down. shut down ok, then i changed the graphics card from x1300 to 7950gt, and it freezes on boot screen switched back to x1300, still freezes on boot screen. set jumper to clear cmos, turned pc on, freezes at boot screen again then i put x850xt in, freezes at boot screen. removed 6 pin power connector to x850xt, get a warning that says "NO POWER CONNECTOR TO GRAPHICS CARD", so i turn off and connect it. still freezes at boot screen. fucking hell, all i did was swiTch a graphics card, then when i put it back it doesnt care!! WHAT ! seriously i spent all day fixing this thing up and now it just fucks me over, im so annoyed any suggestions?
