I have noticed the past 24 hours that my network utilization on process ntoskrnl.exe is up to 93-99% all the time. what is this process and should I be worried? I have port 8080 open from the outside for sab but that's it.
View 7 RepliesMy process "System" which leads to C:WindowsSystem32 toskrnl.exe uses about 10 CPU all the time. I'm wondering what it does, and if there is a way to lower the usage.
View 2 Replies View RelatedThis just started happening recently and I don't know why. Performance monitor doesn't show anything irregular, neither does process monitor.
I've run an sfc scan and chkdsk too as well as updating everything and seeing if disabling av software work but nothing has.
I've noticed that when I leave my pc for some time and the screen savers come on, then the screens go blank (my machine doesn't sleep or hibernate) when I use the pc again I can see that during the time the monitors had turned off, the CPU usage was at or above 50% ? When I use the computer after that, watching movies, photoshop etc the cpu usage is much less than that!
View 1 Replies View RelatedI installed Windows 8 over the last weekend. Things were working fine for the first five days. Just day before i started seeing apps being unresponsive and noticed that the Task Manager showed 100% disk usage. The process taking the most disk is 'System'
Yesterday things became worse; the startup started taking way too long; after starting up launching any app takes up to 10 mins and the HDD led is constantly on; making the sytem completely unstable and stuck.

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.

I have 2 PC's. Both are now running Windows 8. The main PC was running Windows 7 and I there mapped a network drive (z to the Windows 8 PC. It worked very nice. The second PC was also shown in "networks" in "my Computer" right after boot of Main PC. So network for sharing is set up properly on second PC.
After installing Windows 8 on main PC, it is still working, but the time spend waiting for the network drive is waaaaay longer now. The name of second PC "Photo-PC", is shown right after boot, but when I first click on the name, and get this error:
Networkpath not found. Errorcode 0x80070035
If I then wait about 20-30 seconds and then click again on "Photo-PC" then I have access to all shared drives, included my mapped network drive Z:
How can I eliminate this 20-30 seconds delay after boot?
I have given up setting up a homegroup, never had it to work, but "oldfashioned" network drives used to work
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:

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.
As soon as I start an application (Cadence Allegro PCB Designer 16.5 but I don't think it's relevant) my CPU usage gets to the roof and stays there long after I killed the application and I believe I every associated process. The CPU usage is so high that the battery will be drained after about 45 minutes (It usually last about 3 hours).
According to my task manager the responsible is "Service Host: Local System (Network Restricted)". As a matter of fact, preventing the executable from accessing the network sort of solves the issue. I don't believe I need that executable to access the network but I'd like to understand what kind of network service can consume that much CPU (was actually affraid of overheating) and to know if there's a more appropriate way to solve this.
I have installed the newest web browsers: Opera, Firefox and IE. I have the lastest version of Adobe Flash Player. When I want to watch any video on Youtube - it's almost impossible, cause it jams. Even when I down it to 360p. It's about 50 percent of CPU usage, sometimes even more. I tried to install older version of Flash Player - no effects.
View 9 Replies View RelatedI've been having some issues with the system process using around 10-20 percent of my cpu lately. I gather that the general solution is to find a problematic driver using kernrate and process explorer, but I can't seem to find a version of kernrate that will work on 64 bit machines.

View 9 Replies View RelatedCurrently I have a home network and need to do some rewiring but wanted to know if a software solution exists.
Right now I have the following setup
Code: +------+ +--------------+ +--------------------+ |Modem|----------->|Wi-Fi Router |+-------->|Desktop Computer| +------+ +--------------+ +--------------------+ + + | | | | +------+ | +-------------->|Server| v +------+ +----------------+ |Laptop Computer| (wifi atapter is OFF) +----------------+ + | v +---------------+ |Network Storage| (security storage computer NAS200) +---------------+
My laptop computer is the only computer has 2 NIC and thus I have set it up so that no other computers on my network can reach the network storage. I will be changing how things are wired together so that the network storage will now be connected through the Wi-Fi router, however I want to maintain the security of not allowing other computers on my network from reaching the network storage.
Is there a way that I can do this? Can I put the network storage computer on a different workgroup from the other computers? Can I have my laptop see 2 work groups so that it can see both the network storage and my home (unrestricted) LAN?
I am running windows 8 (not 8.1) x64 on all my computers. My router is a Linsys E4200.
1. When I start windows and it tries to connect to the internet, it brings up a dialogue box to say "the password supplied is incorrect"
2. After opening settings I the password box is blank, even though I chose remember password. After inputting the correct password again, then try to connect it still brings up the same error msg.
3. Then I have to create a new PPPOP internet connection, with the exact same data AND chose remember my details -hey presto internet access until shutdown.
then repeat step 1...
I finally figured out my Wake on LAN issues for my HTPC with my recent upgrade to widows 8.
Now my issue is how do I disable the 30 sec wait time for approval by currently logged in user when I try to establish a Remote Desktop connection?
I have tried to change the settings in gpedit allowing admin access with out users permission but it doesn't seem to work in widows 8.
So, I have been running 8.1 pro for some time now. During the last 2 or 3 weeks, I started having a login issue.
It loads bios, loads windows fine. I get to the login screen, and it seems to take forever to recognize internet connection. Gives me the little "!" over the internet. I put in password. Takes about a minute to finally log in.
I have gone to start up in task manager and disabled everything. This does nothing. I have changed from a live to a local account. Nothing. I have not installed anything recently other then video drivers. Internet seems to work fine while logged in.
Have all the most recent mobo drivers.......

I've set several folders and drives to be shared on the network with read/write permission. The problem is that each time I start Windows, I can only Access the shared items across the network with Read permission, instead of the read/write I originally set, so I have again to right-click > share with > read/write.
View 2 Replies View RelatedI am using windows 8 and from time to time the whole laptop freezes with only short moments where you can move the mouse until it freezes again.
And today I was using word and the program wouldn't let me work in it, you could see the mouse movement at the bottom of the screen only. I had to shut it down using task manager for it to work again.
After making clean install of Windows 8.1 (before I had Windows 8) then my laptop started to hang from time to time.
Selecting tiles in Start screen with keyboard is normal as it used to be , mouse moves normally but HDD light is not on or blinking. Clicking with mouse does do nothing.
When I click fast many times then it finally opens App from Start screen on a program in Desktop mode but everything is slow for 3-4 min. Then it automatically works as it should be, like nothing would be wrong.
Ocassionally my computer will become so slow it's almost unresponsive, when I check task manager it says 7.2 of 7.9GB of ram is in use. Even rebooting it, it will come back with high memory usage, sometimes rebooting it, it goes back to normal
Most of the time it is normal and fast, I can have Chrome open and have 10 pages open and usage is about 1GB, but what causes this to happen occasionally when I'm just surfing the internet?

View 9 Replies View RelatedI'm having to use a dark high contrast theme because when I look at normally it makes my eyes want to burn and I don't mean that sarcastically I mean that seriously my eyes start feeling like their burning when I'm staring at a screen that is so bright. So I've used the Microsoft high contrast black theme to make using my computer easier on my eyes however I'm experiencing a problem when I need to go and print something.
I'm printing out documents that are displayed in Internet Explorer and the problem is that the printed document comes out very faded almost as if the contrast is greatly reduced.And on the contrary, if I use the Microsoft high contrast white theme than the documents that I print from Internet Explorer come out printed very well with the same printer settings and all.
Is there anyway I can correct this short of having to use the high contrast white theme which just makes my eyes burn even more?

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.
