I have a Dell Dimension 4700 Desktop currently in my possession. 3.2Ghz Pentium 4 Processor, 4GB RAM, ran Win Vistax64 with on built VGA and a high performance graphics card. This computer was used for gaming and I had received it from a family member sine they had purchased a new computer.
The problem with this computer is that when I turn it on, the main fan runs at full speed and doesn't slow down. I also noticed i get nothing on the display in any of the ports on the card (VGA, S-Video, and DVI) nor on the VGA on the motherboard. I was told that there is a switch in the BIOS that you can use to change which display to use for POST but since i can't see anything navigating the BIOS is not going to be a choice. Next is that the computer has Hardware fault indicator lights on the back of it but none will light up to show anything.
I have tried removing the RAM, CD/DVD Drives, Floppy Drive, and HDDs, and all Addition cards inside the computer and still the same result with the fan running full speed constant. I'm leaning towards the motherboard being bad but not sure. Tested the power supply and all seems fine.
Any ideas here...
