G75VW random audio and graphics spike

[sunny]

Hi, this is my first time posting here so i hope this is the right place for it.

Just got my G75 2 days ago and since then, i have been getting random and annoying graphics and audio lag/spikes. When i have continuous music playing, i notice that sometimes the music will lag and create a very low screeching sound for maybe 2 seconds, after this ends, everything is back to normal.

As for the graphics, when i am playing a game or even surfing the web, i get a short lag spike or freeze. This freezes the screen or creates a huge lag for maybe 2 seconds and then back to normal. Furthermore, i notice sometimes when im on video call with my friends (skype). The video screen will occasionally flash green and return back to normal. I am not sure but both audio and graphics spikes could be happening at the same time. This is very fustrating.

I have tried installing the latest graphics drivers but it has not fixed the problem. Could it be hardware damage? or is it something to do with my drivers?

Thanks!

PS: this issue happens at least once every hour

If you look at some of my previous post I am getting the same exact problem with the graphic card. It's not a faulty hardware issue either - something is just wrong with these laptops. I have gotten two G75VW's from Best Buy and both had the same problems. I'm just returning mine today and moving on to another laptop.

Yeah, thnx for the insight. here are some updates

I was just running Cryengine3 the sandbox tool and suddenly my screen blacked out. When my screen reverted back to normal (instantaneous), i got a notification saying that my graphics card crashed and successfully recovered itself.
This is also my 2nd g75, i swaped by g74 for this actually becuase of a touchpad issue

So ... this is a known problem, and there's nothing we can do about it?

I'm having the same problem.

When I'm watching a video, playing music, or playing a game, I will experience these random occurrences where the audio suddenly stutters really bad. It's like some kind of massive CPU spike. The mouse cursor stops moving and the audio will screech really bad.

This is not an acceptable problem. This cannot be over looked.

Is my only option to return this laptop and buy a different brand?

Mine did have some lagging issues, but I never noticed anything so drastic for audio or video. I reinstalled Windows 7 and I have no lagging issues. Could be software related if that's the case.

Download DPC Latency Checker (http://www.thesycon.de/deu/latency_check.shtml) and run it when your PC is idle. Do you see red spikes? Those spikes are caused by drivers misbehaving. Read the download page to learn how to troubleshoot with this diagnostic utility. Come back if you need more help.

Interesting. I downloaded this tool and, while sitting here doing nothing, my G75VW-A71 is showing red spikes on a regular basis. Perhaps once a minute, or once every other minute.

This is all well and good to know ... but what can I do about it?

Thanks.

Edit: Here's another image.

That was while viewing a video on youtube. Here's the interesting thing, as soon as the video was done downloading, the frequency of the red spikes declined.

Could it be the wireless network driver?

Edit 2: Updated the wireless driver. It didn't help.

Edit 3: Updated the "Intel(R) 7 Series Chipset Family SATA AHCI Controller" driver. That required a reboot. After rebooting, the first thing I did was start the latency monitor and let it run for a minute or so. Then I started Google Chrome. This was the result:

No help. The journey continues. I wonder if the problem is related to disk access? Since starting Google Chrome triggered such a large spike. Hmm...
