I recently bought a Albatron KX400+pro. motherboard for an up-grade to my computer. I installed the new board along with a Athlon 1800 XP CPU, 256 DDR PC2100 menory, 350 Watt Power supply,GForce video card,and my existing drives. On boot I got drive activity but no display. Is it possible to test a motherboard to see if it's defective? I have a 3 year guaranty.
