Just upgraded to a new mouse and keyboard and somehow my computer, upon restart, will not boot, even to the post, or at least I cannot see what it is doing as the monitor is showing only the power save mode. I have Award bios and am hearing only 2 tones repeating over and over like a siren every other time I try to boot. The fans and hard drive seem functional as they are running. I have tried a new monitor and a new video card with the same results. I have an asus k7v but the manual is thin and I find no help on the asus web site. Can anyone tell me what is going on here?
