|My HP Pavilion Slimline s3100n is doing the same thing. I tried other known working monitors, speakers, keyboards & mice. Nothing is getting any signal outside of the computer. The memory & hard drive tests fine in another computer. The fans work, the power supply seems to work, the CD drive drawer goes in & out. |
I am wondering if it could be the low voltage supply from the PSU. The video in built-in on the motherboard. I thought about trying a PCI-E vidoe card ut with no response from the POST or lights on the keyboard/mouse I'm thinnking it's the CPU or motherboard. Any ideas?
