computer build problem -- no video output
by beProactive - 6/28/12 8:40 AM
I am having a problem with one of my first computer builds. It is all old parts; I am building outside the case to test the main components: the cpu (w/ heatsink & fan), the memory, the graphics card, and the power supply. When I short the two pins to power up the computer, the cpu fan runs fine; however, my video card (PCIe) does not work. I have tried multiple video cards too, so I believe this is not the problem of the video card. I think the problem may be with the power supply, because when I plug in a video card that has worked in other PCs previously, its fan does not even run.
I am just looking for someone to point me in the right direction. Might I need a new power supply? What is the best method to troubleshoot this kind of issue?
Thanks in advance for any and all help.
