I've been having this issue with my three month old HP Envy 14 notebook for a few weeks. Sometimes when I'm playing games (Skyrim, Starcraft 2) or watching a movie on WMP the computer will just lock up. No mouse, no keyboard, and a strange buzzing noise. The only option is to restart. This is exactly what the buzzing sound is like: http://www.youtube.com/watch?v=h-msujgDmsU

Also, it has happened a few times while doing non-graphics intensive tasks such as using Google Chrome or Microsoft Excel which makes me think its not related to the video card.

The frequency of the freezes is very random. It's only happened about a dozen times, but I have this problem on another desktop quite frequently so I'm not sure if its HP related.

Here's a quick overview of my system:
• HP Envy 14 Beats Edition Notebook
• Windows 7 x64
• i5-2430
• Radeon HD 6630 switchable graphics
• 6GB 1333MHz DDR3 RAM
• 80GB SSD (OS)
• 500GB Conventional HD (Games)
• Stock BIOS settings; not overclocked

Attempted solutions:
• Updated ATI drivers
• Reinstalled sound drivers
• Uninstalled Antivirus
• Ran Memtest86+ for 6 hours; 5 passes (no errors)
• Windows Event log shows nothing in particular (http://i.imgur.com/3LEi1.jpg)
• Used CoreTemp to monitor temperatures - nothing out of the ordinary (45-55 on idle, 65 max when gaming)

Ideas?

Well the sound is coming from the speakers, not inside the notebook. I checked the vents; there is little to no dust, this is a pretty new computer.

Well its out of the RMA period, but still under warranty. I have heard so many horror stories about HP service so I'd rather not send it in if I don't have to. Figured I'd consult some expert advice.

explain out of rma but still under warranty,because if you open it and could not fix then it would be hard to have warranty service

return and exchange is not for repair of defective unit under warranty,they use that if your not satisfied with your purchase.but the should fix it under legal warranty time of 1 year go where you bought or a hp service center with purchase invoice and a copy of it but keep the original,to have it repair from them it up to you
