Y570 video and sound randomly freezes for a short period of time

[ Edited ]

Hello,

 

I recently bought my Y570. While i was playing a video game(League of Legends), the video froze, and my sound got distorted for only a second or two, it jittered. I thought it was nothing to be worried about.
Then while I was watching a youtube video the same problem occurred, video froze for a second a sound jittered again. It also happened while I was installing Java jre on my laptop, it had to install 3 files, and during every installation while the status bar was empty it first froze and sound got distorted (I was listening to music while I was installing) and then the installation would actually start. It can be described as Lag of some sort. Has this problem happened to anyone else and is there a solution? Nvidia graphics was on during the video game and youtube video, but I can't remember about the installation.


Thank you for your time.


y570, i7 2670qm, gt555m 2GB, 32GB SSD, Win7 Home Premium 64bit.

Re: Video and sound randomly freezes for a short period of time

Ok, so I opened the Event Viewer>Summary of Administrative events and there are 144 errors in the last 7 days column. I'm not sure if this was the information you were looking for, but if you give me a more detailed explanation of what should I do, I will supply you with all the information you need(print screen, event log or anything that will help.).
I don't have any critical errors, I've got 6393 warnings and a 124 audit failures, all in the last 7 days. Aren't those numbers a little too high up? Oh, I forgot to mention, I am new to Windows 7, I used the XP for the last 7 years, but I know my way around computers so that won't be a too much of a problem.

Re: Video and sound randomly freezes for a short period of time

I checked the system log, and apart from some Warnings, everything seems to be OK. I made a mistake, that was the information column, I had 265 warnings in the last 7 days, not 6393. Ok so I pretty much ruled out the Nvidia card, it happened 2 times while the Optimus switch was off, so I think it's not GPU bound. Any ideas?

1. Kernel-Processor-Power(always in group of 8), Message: "The speed of processor 7 in group 0 is being limited by system firmware. The processor has been in this reduced performance state for 2 seconds since the last report.", the number of the process ranges from 0 to 7, bottom-up.

2. Wininit, message: "Custom dynamic link libraries are being loaded for every application. The system administrator should review the list of libraries to ensure they are related to trusted applications."

3. k57nd60a, message: "Broadcom NetLink (TM) Gigabit Ethernet: The network link is down.  Check to make sure the network cable is properly connected."

4. WLAN-Auto-Config, message: "WLAN Extensibility Module has stopped. Module Path: C:\windows\System32\IWMSSvc.dll".

5. WLAN-Auto-Config, message: "WLAN AutoConfig service has successfully stopped."

6. mfehidk, message: "Process **\mcshield.exe pid (6128) contains signed but untrusted code, but was allowed to perform a privileged operation with a McAfee driver."

 

Those should be all, I copied the name(source), and the information below.
P.S.. It happend during typing of this message so I refreshed the event log, it had no information nor warning matching the time stamp of the hiccup.

I think it's >>The speed of processor 7 in group 0 is being limited by system firmware. The processor has been in this reduced performance state for 2 seconds since the last report<< check out Pito's post about using  ThrottleStop, I don't think it will fix the problem , but I believe it should fix the symptoms.

Re: Video and sound randomly freezes for a short period of time

have you also tried to flash bios update? also, please, try safe mode if the issue persists to make sure it's not related to drivers.

Re: Video and sound randomly freezes for a short period of time

Ok, so I tried Pitos solution, it didn't work. I have now disabled turning off my HDD for saving power since I read somewhere that Western digital have some problems while going from idle to reading/writing. I have the latest version of BIOS, v2.09 so I think it doesn't need flashing. If the HDD thing doesn't work, I'll try to run it in safe mode.
velenoso666:  Pitos problem was happening only while playing games, and it was lagging throughout the game. My problem happens randomly, installing, playing games, watching videos, etc. It's only for a second or two and it feels like the HDD has hiccup, it stutters. Can't really explain it well enough.


Thanks for the help, i'll update tomorrow.
