Trophy 1200 overheating low mileage!

hey, just finished huge ride across europe on one. Look at radiator and water pump, check oil levels and type of oil used. sounds like a blockage in water pump and or, radiator or hoses. Check electrical fan is running after bike stops? If fan is not working the bike will over heat as it requires fan to draw air trough the radiator constantly. Terry Tourer Australia

HP Pavilion mute button stays red...won't disable (unmute)...I have no sound.

try downloading and installing the latest audio driver from the HP website. choose your operating system and the website directs you to the drivers. sometimes windows updates install the wrong drivers ans causes the hardware to malfunction properly, so try uninstalling these updates using system restore point, if this doesn't work do the first step.
