I have a home assembled desktop. Worked fine until video would sometimes blink and turn off. Replaced video card. Didn't work. Replaced motherboard. Didn't work. Changed monitors. Didn't work. What have I done?
I have checked all connections, removed and replaced cards, etc. CPU will start up but monitor gets no signal.

The first thing that comes to mind is, do you have a large enough power supply? The second thing that comes to mind is, do you have a spare video card that you can try temporarily?

Since you built your own, I'd assume that you know all about the danger of static electricity and that simply handling any computer component can destroy it. Sometimes, damage can be done that takes time to show up. And it could have been someone else handling it, or simply a bad video card. (or monitor!) I recently had a monitor that would no longer switch from the power saving mode back to real mode when the computer booted up, and I suspected the video card. But when I tried a different monitor, it worked perfectly and it's been working fine ever since.

Welcome to BC.

When you changed the motheboard did you also change the RAM and CPU?

Does this happen during any specific application?

And would you please provide us with the specs for your computer.

Motherboard, CPU, RAM (amount and number of modules), PSU, OS...

btw...chips/ICs are usually what are damaged by electorstatic discharge (ESD), and the damage is usually instantaneous and the problems associated with them usually isn't intermittent.
