Moved Harddrive to new computer, get blue screen

So recently I uprgraded my computer to basically all new components except for the hard drive. When I went to start my computer up, windows tried to repair the problem, but was unsuccessful and ended me up with the blue screen that tells me I may have a virus or some other possible things.

My question is how is this fixed and is it easily fixable? I also have a SSD card too which may or may not make this situation a little bit easier but I'm not to sure.

Also the hard drive came from a pre-built pc I had bought about 2 years ago. It came with a disk with Windows 7 in it, but was the disk it was on was also the disk for the motherboard set up.

Do I need to buy Windows 7 again or do I need a new hard drive? I just want to find out so I can finally see what my pc looks like now. The anxiousness is killing me.

    Windows was setup with the prior hardware in the system it was attached to.
    You cannot move a hard drive from one system to another.
    Because the hardware differs, and all of the drivers installed are for the system it was took out of.

    You have to install a clean version of windows 7.
    If the prior machine came with windows pre installed.
    It will be an OEM version and will not install with the new hardware you have or not validate the licence key.
    Because it is tired to the hardware in the other system.

    Ok, so I do need to go and buy Windows 7 again in order for my hard drive to get rid of the old drivers and so it can also install the new drivers correct?
  3. That's almost crazy, you just changed all components of your computer except the Hard Drive which means that the basic motherboard drivers, graphic drivers and other basic things are completely changed... You had to get a bluescreen or a dead computer with that hard drive being booted up. And if you computer boots up, all your screen will be like destroyed, the resolution will be like 800x600 or 1024x768. You'll have to install all the drivers of the new build and if you can't do that, you'll have to backup your HDD and install a new copy o Windows. I just have an original CD of Windows 7 and I can re-install as many times as I want without any major fuss. Just is that I'll have to re-set all the things of my PC.

    You need to buy a new license of Windows 7 and do a clean setup on the new computer. Since the original drive was from an OEM, not a retail setup, you can't move that setup over in any way to a different computer.
