I have my XBOX 360 connected via ethernet cable and often times when I attempt to view Live TV or play a recorded show through the XBOX, it crashes the computer. I have 64 Bit Windows 7, 4 GB RAM, 2.8 GHz quad core, 1 GB XFX Radeon HD 5670, and use the AVerMedia A188 PCIe Pure ATSC TV Tuner. I've even gone as far as reinstalling Windows 7 with the thought that it might be a 3rd party software issue to no avail. It does work about 70% of the time, but its really annoying waiting for the computer to restart. Why does this keep happening and what can I do to fix it?
