No Display After BIOS / Windows Or USB Controller Update

I recently bought a computer and it had an OS issue, so after some tinkering I was able to install XP onto it, then install 7. Everything went relatively smoothly. I had downloaded the drivers and updates from HP's website for my model computer. I went through and started installing them one by one. I came across the BIOS one and it said it couldn't install it. There was also a Windows update that wanted to install, but at the same time I had already moved to the next driver, a USB controller, and that one had completed it's installation and wanted to restart. I had stopped the Windows update and then prompted it to restart the computer.

It shut down and when it came back up, it brought up a black screen with some text, that then flashed blue for a split second, then turned off. I went to turn it back on, but there is no display now. I currently have a DVI-HDMI that is plugged into my laptop, but it says it can't recognize anything (though it had been doing fine before all of that). I do not have a Windows 7 disc. I had downloaded it from the internet and mounted it using Daemon Tools lite and all went smoothly, so I don't think that was the issue. I have a feeling that something went wrong. I've tried hitting F8, 9, 10, and 12 hoping that it would enter some mode and the display would reappear, but nothing. Do I need to burn Windows 7 to a disc and try it that way?
