Almost HD Res Problem?

Hey there all'ya. Just bought a HP G62 and i have installed the newest drivers i could find. Everything works fine until i play any online vid from YouTube that is greater than 320p. Basically, every movie bigger than 480p freezes and only the audio stream is being played. Also, when connecting the G62 to the tv set (42' LED Samsung) by HDMI, for movies higher than 720p, the sound would fade away regularly on an average of 30 seconds.
Does anybody knows what can be done? Please help.

Thank you!

 

Regarding the drivers, did you download them from HP or the video card mfr.'s website?

HP.com isn't always up to date on the latest video upgrades and patches.

Go to CONTROL PANEL>SYSTEM>DEVICE MANAGER>DISPLAY ADAPTERS and check what brand and chipset/model of video card (or on-board video) your PC has (examples: NVIDIA 9800, ATI RADEON 4850, Intel, etc.)

Go to the video chipset mfr's website (NVIDIA.com, ATI.com or Intel.com) and check for/download the latest drivers.

If this doesn't work (and you're still within the store's return/exchange window), I'd personally cut my losses and try a different brand or model PC.
