Hello, I have 2 of the same exact older presario models (5441) that i'm trying to get in running order, these have been sitting around for awhile but seemed to be in working order when I put them up. Problem seems the same on both of them. Now heres the situation, I hit the power and the machine seems to switch on, the harddrives spin up and the front LED's light up. But from what I can tell there is no sign of any post, ive tried changing out memory/ps and also adding a PCI video card and no go. NOW what has caught my attention is that the CPU fan doesn't seem to spin up, ive tried changing it and nothing, I have also tried the fan in another system and it seems to be working fine. So any ideas? Btw the boards are Gigabyte models, after that there isn't very much I know about the boards. Thx
