Alright... I bought a new Infinity 865PE Mobo, installed it, it boots up, it does RAM check, detects the HD and CD and Floppy, and then goes to a black screen with a blinking white line in the top left corner. Before it goes this far I can sometimes get into BIOS, where I set it to boot from CD. Still does the same thing. Mobo, processor, power supply, graphics card are all brand new. Any suggestions?
