I installed a new graphics card to gain an HDMI port for my projector. After installing the I had thought I was randomly loosing my keyboard and mouse due to the power supply being too small so I bought a powered USB hub but that didn't help. Turns out the computer is locking up not just the keyboard and mouse. I bought some new heat sink paste on the cpu and cleaned the fan, also didn't help. After doing some reading I ran a couple registry cleaners and some other programs but didn't help. I'm stumped, it has to be something with the new video card conflicting with facebook but I just don't know what.
