[House of Pancakes]

Or something along those lines. This pops up. I just got a new video card and installed it. Everything was working fine. I left my house, and came back, and this message was on the screen. Last night I tried setting my BIOS correctly, but I didn't see much I could do there. I changed the boot order so my hard drive is first. Basically, my computer isn't reading my primary hard drive. It even said "Primary Master Hard-Disk Fail" once, but I haven't seen it again. I just opened up my computer and made sure all the cables were plugged in correctly, and it still doesn't work, but then again, I'm not even sure where my hard drive i on my motherboard, and I'm not sure how to change cables and whatnot.

Is there anything I can do here?
