Hi,

I think I have hardware that is failing. Computer will boot but monitor is blank unless I unseat the video card and reseat it in the motherboard slot. Last time I did this was Monday and computer worked normally until today Thursday. Same issue. I tried rebooting, unplugging all power and cables to monitor and PC. I swapped out the video cable. The only thing that works is unplugging and replugging the video card back into motherboard. How do I narrow it down and determine if I am having a video card or motherboard failure?

- i7 processor, Win7 pro, firepro card, computer is less than 1 year old
 
You swap the video card. By taking one of the components out of the equation and the problem still exists, that component might not be causing the issue.

What you also can do, is to examine the motherboard and see if there is broken or busted caps. Update the bios of the motherboard (regardless if you have the newest) in case you have a corrupted bios. Check and see that you have suffient amp on your PSU according to your GFX cards spesifications. :)

What you already know, is that this is not a software/os issue, but a hardware or bios issue, since it happens at boot.

Have you ruled out the monitor/checked the monitor with another computer?

Oh, and when you troubleshoot computerparts at boot level, make sure to disconnect components not needed to troubleshoot (harddrives etc). Not getting image can just as well be the memory, even if you have to swap the GPU to make it work... You need to rule out that it doesn't "work" because you are forcing a redetection of hardware due to taking GPU in and out.

Use a single stick of memory. Set memory timings manually in the bios according to the loosest spesifications described in your memories capabilities. See if you still have to reseat the GPU card. Run mem86+ and see if you get any memory errors.

Sorry that this might seem unorganized, but I don't know your hardware and don't know how far you have come in the troubleshooting process and which parts you already have ruled out. Memory incompatibility and errors is one of the major causes of boot issues.
