So, I just installed my GPU, last piece to my computer and I hooked it to my VGA monitor using a DVI to VGA converter on my computer. It turns on, but no signal. I read somewhere where some guy hadn't hooked the PSU to CPU, I didn't do that because I didn't know that was necessary. I thought CPU drew power from mobo. So if that is the issue, I only see one thing where the PSU could hook to mobo and that is at a slot labeled EPU. If this is the issue, please tell me so and if I should plug into the EPU slot and if not, please help me.
