Is Asus Geforce GTX 750 Ti OC 128 bit 2GB compatible with MSI Z77A-G45 motherboard? It worked with Z77MA-G45 and 400W PSU. Now moved it to my wifes computer with Chieftec 500W and black screen. Caps lock sometimes flashes, fans are working but no display. When I put back old videocard it still works.
