computer screen freeze

[miltonmeier]

while watching tv through my pc after 45 minutes or so the screen will suddenly freeze showing strange patterns of color and the keyboard and mouse are inoperable also, i have tried a different tuner stick to no avail, the only way i can get the pc going again is to shut it down on the tower and then restart it but, the problem will always occur again. my pc is only 5 months old and has already been back to where i purchased it from and has not been fixed. could the problem be a sound or graghics card issue?

You might wanna think of using your warranty here before its too late to save you from the troubles of replacing any parts.
