I have a fairly new HPE 400Z desktop with a AMD Phenom(TM) X4 945 quad-core processor [3.0GHz, 2MB L2 + 6MB L3 shared, up to 4000MHz], and 6G Ram. I began to have an issue of my computer hanging when entering any text in a search window, atttemping to type in a web address, type my password when my computer boots up, evening when trying to enter text in this window to explain my issue. I am not sure if this is a Windows 7 issue, however since it appears to happen when on the web and at boot up i assume it is. I have run the latest version of Norton, malwarebytes, and cc cleaner but nothing has worked. I do have a wireless keyboard and used a usb keyboard and the same issue exists. Any help would be greatly appreciated.
