Building a new system for my daughter & am having a problem. Gigabyte P35-DS3R. E4400, X1950Pro, Patroit 667. The video card is a known product, was used in my old system. as well as the PS & the hard drives & ram. When I install all the parts, the machine starts, stops, start, stops, start, stops about 4 times for 5 seconds each. No video on the screen at all. Just a black screen. No bios version, no ram check, ect. Can't see anything to get into the bios, have tried. After the 4th time, all the fans, (video, case & cpu) stay on. The hard drives are powered. I have tried all the new parts as well as the old in my system & all works. Any ideas? My mother board is a GA 965P-DS3. The new one listed above. Thanks & Merry Christmas.
