Stumped; Random freezes, mouse unresponsive, buzzing sound

Specs: Windows 7 x64, i5/6 GB DDR3
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-ms...

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.

I'm running the computer on the ATI card when this happens. Here's a quick overview of my system:

• Windows 7 x64
• i5-2430
• Radeon HD 6630 switchable graphics
• 6GB 1333MHz DDR3 RAM
• 80GB SSD (OS)
• 500GB Conventional HD (Games)

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

Ideas?

You seem to be running TWO AntiVirus programs.

Semantec AV & Microsoft Antimalware (Microsoft Security Essentials). Running TWO AV programs can cause problems.

Laptops shouldn't have Resource issues but that is what it sounds like to me. Years ago Sound Blaster cards used 2 IRQs and would cause issues like that.

Try booting into Windows Safe Mode (F8 at start up) Go into Device manager and see if you may have more than one identical listing for sound or graphics. Check what IRQs are being shared.

Also, check the temperatures in the BIOS, if available, and compare them with the 3rd party monitoring program. You didn't specify what the temperatures were either.

Have you had to re-install Windows 7? Are you trying to overclock somehow (software)?

I uninstalled Symantec AV and tried Starcraft 2 on "high" settings and it froze after 10 minutes. Frustrated, I rebooted and tried the game on "low" settings and I was able to play for 45 minutes with no issues. Not sure what to take away from this as it has froze on "low" before in the past.

"Try booting into Windows Safe Mode (F8 at start up) Go into Device manager and see if you may have more than one identical listing for sound or graphics. Check what IRQs are being shared."

Sorry, pardon my ignorance but what am I looking for here? What is an IRQ?

Also, how do I monitor temperatures in BIOS? Software monitoring is giving me 45-52 degrees on idle/browsing internet, and maxing out at 58-65 under gaming.

EDIT: Just froze again with just Google Chrome and Adobe Illustrator open. Is this indicative of bad RAM?

An IRQ is an Interrupt Request. Windows 7 manages resources pretty good. I only mentioned it in the event that there might be a conflict.

To View the resources go to Device manager and click View> Resources by type to see what hardware uses what IRQ. If Windows 7 is managing these settings you will see many IRQ listings. If not there may only be maybe up to number 22. In that case you could have 2 high bandwidth devices using the same IRQ.

When viewing Device manager in safe mode it MAY show duplicate listings of the same exact device. In the case of graphics of sound devices that should not happen. I haven't seen this in Windows 7 but it is easy enough to check.

After reading your last response #2 I am guessing the GPU is overheating.

Are you using an external display or cloning internal and external?

Does Coretemp monitor GPU temperature?

OtheHill, first and foremost thank you for the continual help, I really appreciate it.

I logged on under Safe Mode and looked for duplicated audio/video devices. I'm not sure I found anything. I have attached screenshots here:

Safe mode did NOT show the ATI card obviously, but under normal operation, both the onboard and ATI devices show under IRQ. What do you make of this?

Also I don't know if you saw my EDIT in #2 but the computer froze outside of a game. I just tried starcraft again and monitored the GPU temps and the max it rose to was 58 deg. FWIW, the computer doesn't feel abnormally hot at any time and all the ports are open to circulation. It's a relatively new computer so I'm really stumped.

How many processes are running in Task manager?

I don't know anything about your graphics setup other than reading some reviews. It appears that you can switch automatically from Intel graphics to the ATI graphics.

I am wondering if the readings for the GPU are for the onboard GPU and not the ATI. I assume the ATI GPU is in use when gaming?

One other question. Does your monitoring program monitor hard drive temperatures? I don't know if SSDs even have a way to monitor temperature.

Do you see any pixillation just before the lockups occur?

Finally, you might want to email HP support and tell them what is occasionally happening to see what they say.

Looks like its about 90 processes give or take. I know back in my Windows XP days I could streamline it to about 20; just figured running that many was normal in W7.

I'm 100% sure the readings are from the ATI. On the program I'm using you can select ATI or onboard monitoring temperatures. Also I can view the conventional HD temperature (roughly 36 C right now), but not theSSD.

No pixelation before lock up. Screen just freezes on the last frame.

Finally, I came back to my computer after eating dinner and got an unexpected shut down.

I have 57 processes running and that is too many.

You may just be overloading the system. Use MSCONFIG to cull some of them.

One suggestion is that any programs to check for newer versions are kind of useless, IMO.

If you don't use a program frequently then don't have it running at start up.
