Hi there, here is the problem. I have 2 computers networked together with one monitor and a kvm switch. Since I have mapped the network drives I hardly ever see the other pc going. But I did notice it was rebooting for no reason that i could tell.So I checked the bios of it and noticed the fan speed was 0 fearing overheating i took it apart and lighting blew it out with a handheld vaccum on low (not a full sized vacum but one meant for hobby stuff) as it was dusty. Especially the cpu fan. Now when i turn it on the power light comes on as does the harddrive indicator light but then there is nothing no beeps no output to monitor nothing. And after some time of being on it sounds like the fan speeds up but still nothing else. Both fans seem to be working. thanks wilma2
