I have currently built a system with the A7n266-vm mobo. IT came as a combo and it came with an Athlon XP, 256 mb of DDR pc 2100 ram. When i turn the computer it it does not come up with the startup screen. It sits with a blank screen and just beeps. I have never encoutered this problem before. I have tried all the various jumper settings on the motherboard. The processor is not bad, nor is the motherboard. I have put the Processor in my own system and it worked, and have put my processor in this system and it worked. I cannot get them to work together. Please if anybody has encoutered this or has any suggestions besides using a hammer i would greatly apprecate it.
