Maintenance :: Windows 8.1 High DPC Latency (Annoying Static Sound)
Aug 6, 2014
I found out that windows 8 and windows 8.1 weakness is its latency. For me this problem occurred like 2 months ago (before it didn't happened) , and yes I have messed around with the bios before that happened (now its all set to default ).
Currently I am running Windows 8.1 Update 1 (made a clean install yesterday) latest updates and drivers installed (with a program called DriverEasy) , and I am also running all the default settings in bios currently . I noticed the problem , 2 months ago just like I said before , when I was watching a video on youtube . Since that , I just can't watch some videos anymore with the ANNOYING static/crackling sound , its very annoying .And it also seems that it affects CPU performance and fps drops.Like I said before , I installed Windows 8.1 yesterday , so no minor tweaks have been done to the system .
I have already tried :
-"disabledynamictick" command
-Disabling all unused devices in bios
-Disabling EIST and C1E (no improvment at all)
*-Disabling HPET Mode reduces latency , but pc isn't stable.
Here are my computer specs (its a 4 year old and its really , really bad ):
Here are the screenshots of DPC Latency Checker and Latencymon :
DPC Latency Checker (2minutes):
There are one or two yellow once a while .The values also slightly raise to yellows when I move the mouse , which I think is normal .
Latencymon (2minutes-both pitcures):
The values were raising and falling
The values were raising until I stopped the checking .
My power plan is set at High Performance (when the powerplan was set to Basic , I was getting red spikes in DPC Latency Checker) , and I am running the stock voltage in bios for the cpu 1.28750V.
I realize this might be a hardware related problem , but I am little bit more sure that this is a Windows 8.1 problem hopefully they will fix it in the Update 2 .
Today I noticed that the sound popped , when I started my computer at the windows logo.
Updated all drivers, realtek, nvidia, amd chipset and bios. Remove everything from USB post and booted without services, disabled network drivers.
When I uninstall the nvidia drivers I dont get that much latency, I do a clean install and using different drivers and it always comes back. I read on this thread that its some interfering with the drivers.
My irq's seem strange the Microsoft acpi compliant system has 511 entry's is the normal?
::System::
Windows 8.1 all updated. Memory (RAM) 16281 MB CPU Info AMD FX(tm)-8350 Eight-Core Processor
Whenever I turn on WLAN in my router, the whole network suffers from an incredible latency. No online game is playable, but the download speed itself is not being touched (i.e. fullspeed) and websites load - even if they're a bit slower, it seems. Once I'm switching WLAN off, it is all back to normal again.
I have really no clue about the source of this evil and due to the nature, it's actually hard to google, as you'd only find problems of people that have high latency over the WLAN devices. I'm experiencing all this stuff on my normal LAN PCs as well, though.
Here's a result from an online ping test with an american server. so, no packet loss.
--- xxx.xxx.xxx.xxx ping statistics --- 20 packets transmitted, 20 packets received, 0.0% packet loss round-trip min/avg/max/stddev = 108.842/1149.351/2727.156/878.843 ms
I installed the Windows 8 Consumer Preview last december and since then, all my online games both from local and international servers have been experiencing extreme lag during gameplay and loading. This only happened after i installed the consumer preview and since then has been happening everytime i try playing any of the online games. I tried playing offline games to see if it might be the graphics but did not encounter any graphics lag and the offline games played perfectly.
I've contacted my ISP and one of their techs came over to check my connection and found nothing wrong with it or from the connection from their servers. Even streaming and downloading speeds are normal.
I've checked my connection at speedtest.net and my ping and internet connection are also registering as normal
Now i tried contacting support for 2 of the online games Starcraft 2 and Diablo 3, they requested a pathping file which i sent to them and copied below:
Tracing route to 202.9.67.254 over a maximum of 30 hops
My graphic driver is up to date and i'm running a 2GB RAM 800 mhz + 8 GB readyboost RAM
Seems my problem is loss of data packets during the exchange of data going on during online gameplay.
How to resolve this problem, considering streaming and downloading speeds are fine and only online games are affected, both the game support and isp support are blaming each other for the problem and i'm still left back in square 1 with my problem.
When plugging a microphone or instrument into the mic/line input of my new Windows 8.1 computer, there is a 1/8 or 1/16 note lag in the sound coming through my desktop speakers/headphones. Recording is fine, I'm talking about live monitoring.
I've used an XP computer for several years to record multi-track music, and also to record Skype conversations for a podcast. My mixer has always been plugged into the line in of the factory sound card, and monitored either with my desktop speakers or by plugging headphones into the desktop speakers, no problem.
Now I've been forced to upgrade to Windows 8.1, and the basic function of plugging a mic into an input jack and hearing myself doesn't work. This goes for analog and USB gear. There are HUNDREDS of pages on the Internet about this, since Windows 7, with no solutions.
Here is a video I made detailing the problem, and demonstrating how any proposed fix (update drivers, use the sound card software, try USB, use high performance power settings) hasn't worked.
A month or two ago I purchased a desktop computer, dell vostro 200. intel dual core 2.8 with a PNY GTX260 graphics card. I haven't plugged in the earphones at all until now and I noticed this hissing sound. Its pretty loud, I'm not sure why but whenever I move the mouse a tad, there's another sound that joins in. What could it be? I turn the volume to 0 and I still hear the hissing sound.
My computer is a ASUS cm6730 desktop PC, 64 bit windows 8.1. I run it to my tv like this:
pc ---HDMI---> xbox one ---HDMI---> lg audio system ---HDMI---> tv
I have my desktop tucked away so i use a wireless keyboard and mouse to control the pc. My problem is 99% of the time while the computer is not being used (fully on but no input) it will completely freeze. The other 1% of the time it will happen while im typing or doing something.
The simple fix I have found is to unplug-replug the wireless keyboard/mouse and boom, instant fix! the problem i have is that the whole point of me having my setup is so i dont have to be right next to the desktop. i thought maybe the problem was the wireless keyboard and mouse but after buying a new one today with built in windows 8 functions, the problem hasnt changed.
One weird thing i noticed is while the computer is frozen if i press ctrl-alt-dlt nothing will happen (surprise surprise its frozen) but the second i do my "quick fix" with the wireless dongle it magically turns back on and the task manager will pop up (so the computer is still getting the keyboard inputs while frozen?)
All drivers are up to date... xbox one is not frozen (i can switch between pc-apps-games no problem, pc stays frozen)... anti virus runs clean... no major system changes sense this started happening a couple days ago. (it froze on me twice writing this message)
I am having problems with my memory it has jumped to 89% and stays there. I tried to restart i looked at the processes it seems that non-paged tools is taking the most. I used RamMAP tool to find this problem.
Over the past couple of weeks I have been getting high disk usage on my computer, causing it to run extremely slowly.
Just after I took the attached screenshot, my System went down to around 6MB/s and the "Service Host: Local System (Network Restricted)" jumped to around 16MB/s Looking in resource monitor the main things causing the high read speed are:
'rundll32.exe' and 'ccsvchst.exe' and one just called 'System'
I recently installed Windows 8.1 on my Inspiron 7520 and I noticed that during the startup the disk usage is around 98/99% of my Samsung SSD 840 Pro 120gb.
I saw a lot of posts where the users complain that, during this high usage of the disk, apps don't open, the system freezes around 5 minutes and after that, there are random high usages, even on idle. But in my case this high usage lasts only few seconds (around 30s), I can open some apps with no problems and never happens again on idle, only if I restart Explorer.exe. If I restart it, it happens all again.
My question is : Is it normal? The high usage only on startup? My only worry is mess up with my SSD due this usage.
On Performance Monitor, the process which writes a lot is System. I disabled every 3rd party app on startup.
I have a new laptop windows 8.1 (64bit) 8gb RAM i7 processor which should be sufficient for the software I use. However on start-up my memory is already at around 80% and stays like that.
The most seems to be caused by servicehost (network restricted) (11) another program is IAStorDataSvc (32bits) even after i updated Intel Rapid Storage it still seems to take some memory. (My system settings are in Dutch but I guess it's pretty much the same as in English).
What could be the cause of the massive memory use?
I have recently discovered that my laptop cooler was going crazy and I didn't knew why, then I started Task Manager and there it was "Windows host process (Rundll32) eating 30% of the cpu.
Notebook specs: Cpu: Intel Core i5 3210m Ram: 8gb ddr3 1600mhz OS: Windows 8.1 x64 pro with the latest update
After around 5 minutes of my system sitting idle, MsMpEng.exe kicks in running about 50% CPU and keeps running until I start using my laptop again. How to stop it doing it.
After I updated to windows 8.1 (from 8), windows explorer is taking up way more memory than it use to. Windows explorer would only use around 37 MB but now it uses almost 300 MB and it shows through poor computer performance. I have tried ending the process and restarting it but sometimes it works and other times it doesn't.
In the future I'm planning to build a new computer to replace this old hunk of junk and I'm curious as to one thing as I'm not entirely sure on this. Just how safe is using the High Performance Power Plan in Windows 8.1?
You see, my current rig is running an old i5 661, normally on the Balanced Power Plan on an old ASUS P7P55D-E Deluxe Motherboard with a GTX 660 and 4GB of RAM on 32-bit Windows 8.1.
But my future plan is to use an i5 4690K with a Corsair H110 All In One Water Cooler for CPU Cooling on a Z97 Motherboard and 8GB of RAM in 64-bit Windows 8.1.
I'm hoping to get quite a bit of performance on this next computer cause hey... I'm planning on using it for gaming and such. But also web browsing and chatting with friends. I hear how High performance is suggested for 'optimising' Windows 8.1 but how much safer is it...
And how much of a performance increase could I possibly see in comparison to the old rig?
My task manager is showing an unusually high CPU usage by the system, anywhere between 20-30% when the computer is idling. I've run the sfc /scannow utility and it found some corruptions, which were then fixed by the DISM utility. However the task manager is still showing that super high CPU usage and no amount of restarts is changing anything. I've attached an image of my task manager.
I have high usage on my laptop lenovo g580 using windows 8. check task manager and I see cpu memory and disk fluctuating up and down to 3% can go up to 100 at times. When I open google chrome. Watch video or play games. I hear my fan turn on and i think my hard drive and i check task manager and i see the problem happening. I did a virus scan and searched everywhere online. I couldn't seem to find a solution. When I am not using the pc its a stable 3 percent but my memory is at 37 which i barely have anything installed but 1 game and a google chrome.
I'm setting up a new laptop running Windows 8.1. I keep finding the Windows Media Network Sharing Service keeps starting up when the PC is otherwise idle and running at 90% + CPU load for long periods. There is no demand for media streaming when the process is running.
What is this process for? Can I disable it or reconfigure it to reduce the CPU load?
I recently got a new laptop, first thing I did was delete most bloatware and such, and there really isn't a whole lot remaining other then OS and drivers. However, when checking the taskmanager recently I noticed it using 80-90% of the RAM. While being under very little use. Only thing was chrome taking up 200-300MB.
The laptop is a samsung 9 series, with 8 GB RAM, so I can't see how it should be having so much troubles when just running on lowgear. I checked and it does have 8GB RAM registered, and the performance view shows it using 6GB of 7,6. Considering there are plenty of windows 8s laptops with just 4GB I couldn't imagine this being normal?
Adding together what is shown by the task manager wont get me higher then 1 GB at most as far as RAM usage, is there any tool giving better information about what is all used? Could it be the quickboot system of samsung that eats up some or some sort of reserve that will let go of some RAM if other programs demand it?
I'm using the same programs as my old system which also had the same amount of ram (2x4GB 1600MHZ) and the usage was very low.
This PC was only built 4 days ago the current ram is 8GB (2x4GB) Corsair Vengeance Pro, 2133MHz, CAS 11-11-11-30, 1.5V
The first two days that the PC was built I noticed the idle usage at 88% and if i ran a program it would hit 100% and pretty much freeze the PC so it's not an error in the display.
Mobo is MSI Z87-GD65 and I'm running Windows 8.1 with no updates.
Probably not anything to do with it, but i'm running beta amd video drivers and it's showing my card as 5GB, I'm planning to uninstall beta drivers and run updates. Just wanted to know of others opinions.
I bought this Vaio with Core i5-3210M, 4Gb Ram, Windows 8 64 bit. I had really high hopes for it, coming from an i3. For the first few weeks it worked fine, but then it started to freeze while watching movies. Then it started happening all the time, and the cooling fan became consistently noisy for working at full capacity.
I was used to opening task manager on older systems when this happened to see if there was a non-responding program and force it closed, so I noticed Task Manager offers some more features in Win 8. Here, I see that CPU usage is high, staying always around 70% and from time to time reaching 100. At this moment, the process taking the biggest slice is called VCS System Tray with 58%.
What's perhaps more concerning, is that Disk usage is almost constantly on 100%. And by this I mean it reaches 100 and stays there for long periods of time, perhaps up to 20 minutes, then it falls down a few seconds and up again to 100. During this time the computer is excruciatingly painful to use. To even open a program takes forever. When this happens, it seems that Chrome is at the top of the list of processes with most disk usage, with about 1-2Mbps, but this sometimes changes and the list can be led by System, Utorrent, Octoshape, VCS System Tray, Communications Service...I think it's not related to any process by itself, but its nearly ALWAYS at 100%.
Finally, memory usage is also pretty high at 78%, but I guess this may be because 4Gb is not too much for this computer. I'm hoping to upgrade to 8 soon. Out of the 10 processes consuming most memory, 9 is Google Chrome (how's that even possible?).
I bought new lenovo ideapad Z400 touch 2 month ago with Windows 8. Last week i upgraded to win 8.1 and recover back to win 8 , since then i have some problems.
When I have the Task Manager open, I notice the disk usage climbing to 50, 75, 100 also the CPU , even though there's scarcely any disk activity going on, the laptop's fan is working harder and very noisy , my processor's speed and heat are jumping high without any programs on.
I tried almost anything, checked for viruses, disabled unnecessary startup programs, clean boot, but it still the same.
Today I upgraded from Windows 7 to Windows 8.1. For some reason, after upgrading, my hard disk usage is always hovering at around 60% usage and my CPU usage is always hovering at around 50%. This is when the PC is idle. When I was using 7, the disk would rarely jump over 30% usage and the CPU would never go above 7% when idle. The sound of the hard disk constantly working away is doing my head in, not to mention it's at around 50 degrees as opposed to 45 degrees previously.
In window 7 it uses maximum 2gb of ram when transfering big file, say an example a movie size of 8gb. now in windows 8 it seems it uses 6-8GB its as if file is transfered into ram first and then slowly copy into targeted disk. just what is going on here and why microsoft decided to do this? if power goes out then all the files is gone and the entire process is actually slower imho.
Is there anyway to disable this? or revert it back to similar what 7 had?
Basically when I start my laptop everything is good for a while when suddenly the CPU usage goes high because of System Interrupts (~25%) and System (~12%). I have tried using LatencyMon to track down the problem and it used to give me alerting messages but now it gives me messages that are all green and nice ("Your system appears to be handling(...)").
NOTE: My drivers ARE up-to-date, but I am not sure my BIOS is. I don't really know how to update the BIOS though, it's a really weird model I have here, that has become obsolete.
*update1* Upon thinking that it might be the wireless driver or the network driver I disabled both, but it didn't drop the CPU usage
*update2*Now I get disconnected from the internet randomly... it may be the wi-fi driver after all
I have Asus N550LF, always on boot or when i unplug the charger power management set to high performance which is causing the battery life to decrease ( wear level 7%), since i found out H.P. causes this i always set it to Balanced but its annoying to do it every time i boot up, any way to set it to default?
So I booted up my pc this afternoon, but notice with my monitoring software, my cpu activity was going nuts.
I opened task manager, and sorted by cpu usage, and " Store Broker" was using app 35% of my cpu just sitting at desktop. I ended it in task manager - what the heck is this and why would it be running?
