It's giving me continuous short beeps. The screen is blank. All dark. Brand new mobo chip and mem, just assembled. Power supply is 550 fatality. It has the 8 pin connector. video card is GTS250. When power supply and video card are put back into old system they work fine. The phase indicators on mobe are all lit. (2 green 2 red).
Old mobo is a Gigabyte p965 with core2 6600 or so. Can't remember. Anyone ran into this before?
