I order the PCI card after read the great review . I own a DELL dimension 2400 and need Windows 7 for online course . after installation , I have have issue after issue . black screen and now I can not connect to ie . no other browser available . seem to be a corruption some where . after install driver , ie do not open and I can not turn anti-virus ware back on . I call Microsoft and Dell to get some help to no avail . I do not know what to do . and this be my only pc . truly frustrating .
