Hi, I have an Ibuypower computer with hd radeon 7770's crossfired. and an i5 3770k. I only got 30fps on minecraft so I thought it was the onboard intel hd 4000. So I uninstalled it and then my screen went black. How do I fix it? When I boot it up it says no signal. Please help.
 
Uhm. I plugged it into the one close to the top next to a little symbol that is a square inside a square.

My computer has no dvi port so I was going to get a hdmi cord instead but my monitor doesn't have a hdmi port. do i need a new monitor to use my video cards or can I use some sort of adapter?
 
i got the computer at bestbuy and bestbuy got it from ibuypower so I got the computer i have on bestbuy.com and copy and pasted the picture. It's all the same components but for some reason I have hdmi ports instead of dvi.
