Have two HTPCs, both have have Zalman 160XT case. I had an ATI 3870 and ATI 2600XT, and both was working fine.


Today, I installed my new ATI 4850 to each PC. After I installed the new card(no driver yet), one PC was fine, and I could reboot and see the windows desktop, and go to control panel then uninstalled the ATI 3870 driver, and installed the ATI 4850 driver, after the reboot, I can see the windows XP was loading, at the same time, on the top right of the Zalman 160XT LCD screen, there is a box says: RGB searching, then the LCD screen changed to blue and another message pops out: No Cable.


My other Zalman don't even show the Windows desktop after I installed the ATI 4850. I can see the Xindows XP was loading, but never got further, the Zalman screen just went to black.


Any one has any suggestions? Thanks in advance !

sounds like incompatible resolution


restart pc ,press F8 continuosly while it is booting, you should get a select startup type. and choose Safe Mode or VGA compatible ( I think that is only vista). Then you can play with settings/drivers.
