Alright, so i decided i wanted a graphic card upgrade from the 6150le on board one. So i bought an XFX Ati Radeon HD 4770. I tried installing my new card the usual way. First i disabled the on board one, since i cant uninstall and remove it. Second, i put the new card in the PCI-E slot, and attatched the 6-pin power cable. Thirdly, i plugged my monitor into the new card. I booted up my computer and recieved no signal. So i plugged it into on board display which still worked. With it plugged in directly to the computer, i got 800 x 600 resolution, so i tried downloading and installing new drivers for my card. That didnt work so i used CPUID CPU-Z to see if it recognizes my card, but it shows nothing is there. i went into dxdiag, and under the display tab, it shows i nothing. i tried the xfx drivers cd, but it gives me the "could'nt detect an xfx product". Is my card faulty or is it my computer?
