Performance :: CPU Not Running At Full Speed Even At High Performance Power Mode

Jan 9, 2016

I've notice that on windows 10 and 8.1, task manager would show the my max cpu core speed is 2.3-2.4 ghz. However, my Core 2 Quad q8400 is rated at 2.66 ghz. I tried changing the power settings in windows and try lowering my cpu temperature, but my speed would never reach 2.66 ghz.

System Process High CPU

Oct 27, 2015

I recently got a new pc with the following specs:

i5 6600
Z-170P Motherboard
8GB DDR4
Samsung Evo 850 SSD

I'm finding myself having high CPU usage from system process. Specifically caused by ACPI.sys+0x1e7f0. (Found that through process explorer)

I'm slightly knowledgeable in all this stuff, but this goes a bit too far for me, and I can't figure out what exactly is wrong. It's just annoying to have 25% of my cpu being dedicated to this.

Performance :: NT Kernel And System High RAM Usage

Jan 25, 2016

Here is my laptop specification:

- HP Pavilion g4
- Intel Core i3 2.2 GHz
- Radeon 6470m (but somehow got 7400 driver and worked) plus Intel HD 3000
- Windows 10 of course
- 2 gigs ram
- And latest drivers, checked with Uniblue's driverscanner and link on other subforum stickies.

It's high memory usage of this process, it starts with ~7mb then grows up to ~200mb on heavy use. This happen with recently windows 10 update.

What I have done is, I do a restart every time I made these changes:

- SFC /scannow
- Update driver (again)
- Turn windows 10 tips off
- Try disable Superfetch
- Malwarebytes scan
- Disabling High Definition Audio driver drops the process usage to normal 28kb, but this somehow rise again to ~100mb.

High Processor Usage System Interrupts

Feb 20, 2016

Since I did a system reset, I started to have the process called " system interrupts " to consume high percentage of the cpu.

I usually avoid this issue by restarting the system twice. Another problem is the computer is no longer able to go into the sleep mode.

Internet Speed Is Fine But Download Speed Is Slow

Oct 19, 2015

I do not know why, but ever since (thats when I started downloading again) I have upgraded from windows 8.1 to windows 10, downloading is really difficult. when I was still using 8.1, I used Orbit downloader to download my files, but since I have upgraded to windows 10, all apps were lost, and for some reason I cant download Orbit again.

Now I have been switching from on Download manager to the other, from Eagle Get, IDM, Jdownloader. still my download speed SUCK, it is slow as a turtle. but when I am playing online games it is fine, my ping is good, when I am streaming videos it is also fast. but when it comes to downloading IT IS SLOW. why ? is it because of the download manager ? I remember updating my Battlefield 4 and the speed is good. but now, it so slow.

Performance :: Slowdown Of System - High CPU - Cannot Find Source

Feb 1, 2016

I opened my computer after having it been asleep all night; everything was working fine until I realized that my sound volume was stuck at a high level and no matter what I changed the volume to, it would not go down. Having had issues with my sound drivers before, I solved this by reinstalling the sound driver. I figured this would be the end of my issues for the day and restarted the computer to finalize the installation. Then windows installed updates, and when I got back into the system, I realized something was wrong. I have Advanced System Care 9, which comes with a real-time monitor of system usage (RAM and CPU), and I noticed that the CPU usage was much higher than it should be--usually it will be around 1-5% when I am not running anything (or just a few programs), but instead it was using 20-90% CPU, and the RAM would not go any lower than 24%.

However, I had had this issue before; Bitdefender Antivirus had started acting up a few days ago using up 90-100% CPU, and I had caught it using Microsoft Process Explorer. Removing Bitdefender solved the problem. So, naturally, I went to the process explorer to check what was using so much CPU again. But this time--nothing. The windows process explorer showed nothing using that much CPU. From there, I began to notice the rest of the problems: many functions of the task bar would not work, such as any of the toolbar icons, or the windows icon, or Cortana. Firefox would not open, either, and I could not get Steam to connect.

Also Ctrl+alt+delete did nothing but bring up an endless black screen, as did restarting. The only way to reboot is to force it by pressing the power button. Therefore I could not reach safe mode. From there I ran a myriad of virus/malware/adware scanners/cleaners/optimizers, none of which found or did anything to fix the problems, though my computer is now squeaky clean otherwise! Eventually I managed to get into safe mode by a very finicky method, which was by turning the computer off during startup which made it do a startup repair next time it turned on, from which I was able to enter safe mode.

And in safe mode--everything works. None of the described issues happen there. I am able to use all the windows features (aside from those blocked in safe mode), ctrl+alt+delete and restarting function properly, and I am able to connect to the internet and use firefox, everything works. So this means that there is something there causing the problems, and it is being blocked by safe mode, but I cannot find it! After running several more scanners, all of which found either nothing, or only small innocuous things, I ran Microsoft Safety Scanner, which found a "severe" trojan which was (I believe) called Dynammer!ac, and I figured this must have been the culprit--but no. Restarting and returning to normal mode resulted in the same problems occurring. Since then I have uninstalled/reinstalled a few drivers that were suggested to me to try, such as sound (the one that I had to replace before the problems started), and the display drivers, none of which fixed anything, either.

High RAM Usage From System After Some Time Computer Runs

Nov 3, 2015

In my computer I use Windows 10 x64 and I have 6 GB of RAM installed. I face the problem of high usage of Ram from System process. Although I hear that this is something normal for Windows 10, this tends to freeze my PC or prompts me to close running programs although I do not have that much open. I updated all my drivers, I also tried everything proposed in various solutions around the web but the problem still exists. Could it be some update of Microsoft? A friend of mine running Windows 7 with 8GB RAM installed in his computer, faces the same problem the last weeks too.

Service Host Local System High Memory Usage

Sep 7, 2015

Here is my PC configuration :

Recently I am getting notification that my memory is low, close some application to free the memory. But I wasn't running any high memory consuming programs. Then I looked into my Task manager and got this :

I am really not sure why this is taking so much memory. This Service Host: Local System continuously taking more and more memory and it moves total memory upto 80% ....

This didn't happen before I am recently facing this problem. How I can stop this so that it doesn't take this unusual memory. I checked windows update but no update is pending.

Performance :: Task Manager - Local System Service Host With High CPU Usage

Nov 11, 2015

From the moment I switch ON my desktop until switching OFF (working for 12 hours) the local system service host is always between 30% to 40% regarding CPU usage.Why? How to stop it?

This does not happen in my Microsoft Surface Pro machine. Both machines, desktop and Surface have the same software installed so it's hard to believe this CPU usage is software based.

Updates :: Machine Stuck On Update With Rotating Dots?

Feb 10, 2016

I have been using win 10 for quite a long time and am happy with it. This evening when I was opening up a word document it behaved strangely . I could shut it down but after that everything stopped working. Ctrl alt delete wont respond. I had to shut down the computer using the Power button. When I restarted the computer . It immediately went into update mode screen with the usual configuring windows and warning about not shutting down the computer .The screen is orange with circulating dots. ( first time I see an orange screen , its usually blue) .At the beginning there was a short indication of % like about 35% but now only circulating dots . Nothing else works . Its already been running for 1/2 hour or so. I will leave it overnight to see whether I can get to the log in screen.

What to do if I cant get to the log in screen ? Without log in screen I cant get to system restore? Is there a way to boot into recovery mode? I do have a Macrium image and a Macrium recovery flash drive. Will windows recognize this thumb drive on boot or do I have to boot into Bios first to change order of boot .

Alternatively can make and use win 10 recovery flash drive from another window 10 machine?

Kept Freezing With Windows Logo And Rotating Dots After Just A Few Seconds

Mar 3, 2016

I just upgraded my previous rig- so keeping the motherboard, CPU, GPU, RAM, optical drive. New case, SSD for Windows, HDD. After building, I ran the Windows 10 installer on the SSD with the HDD and ODD still connected, went off without a hitch. However after it restarted, it kept freezing with the Windows logo and the rotating dots after just a few seconds. I managed to get into the Windows setup (that comes after that booting screen) once, but when I was going through it the computer froze again. So I tried to reinstall- saw that having peripherals can impact things, so I disconnected the ODD and HDD and tried again. Once again the install itself on the SDD went fine, but same issue, even when I disconnected all USBs including mouse, keyboard etc.

I managed to get into Startup Repair (when the computer restarted after I exited the BIOS, which works fine), but it didn't find anything.The Windows 10 install is off an MBR-partitioned USB burned with Rufus.So what my very limited research and understanding of UEFI/BIOS firmware has led me to understand is that the initial USB with MBR partitioning is likely the issue. So if I re-burn the Windows 10 bootable USB, this time with GPT partitioning.

Windows Start Screen Comes On With 4 Squares And Rotating Dots When Switch On

Feb 15, 2016

After closing down computer the other day, when trying to switch back on Windows start screen comes on with 4 squares and rotating dots, but the screen then just goes black or white with no mouse pointer.

I have tried F8 which goes into recovery mode and I have tried all repair modes, but none of them work.

it must surely be something to do with Windows as I can go into recovery mode.

Unstable WiFi Speed

Mar 15, 2016

My wifi adaptor is a TP-Link WN951N v3.2. My modem is a Netgear DG834G. My wifi speed is really unstable. Normally my maximum connections speed is 9.5mbps, but it is very very unstable. Sometimes the connection speed drops to 0.8mbps for a while. When the connection speed drops I try to ping my modem using the CMD ping command. When I get heavly speed drops I notice that the ping between my pc and my modem is 200/500ms. So really high and unstable. My other wifi devices like smartphones doesn't have problems. They works fine. Here is what I tried to fix the problem :

-Reset my modem to factory settings
-Upgraded my modem's firmware
-To change modem's wifi channel
-Clean installation of Windows 10
-Tried both manufacter driver and windows driver
-Disabled useless settings in Windows 10 like geolocalizzation
-Disabled windows firewall

Customization :: Photos App Slideshow Speed

I'm not very happy with the media options in Windows 10, everything else seems better than Windows 7 except for that aspect. What I am trying to do is use the "Photos" app to select a folder of pictures I want, I then choose Slideshow but it goes through the pictures really fast lasting only a few seconds. I want to have it last more like 1-2 minutes per picture.

Performance :: CPU Fan Running At Full Speed?

Aug 6, 2015

I recently installed Windows 10 on a desktop computer and everything went as smoothly as it could have, with no problems at all. So, motivated by how well everything went with that computer, I decided to upgrade Windows on a laptop as well. The laptop is a Toshiba Satellite L855, with an Intel Core i3-2370M processor.

The upgrade process on the laptop also completed successfully. Now both computers have Windows 10 and so far it has been running... fine.

The only unusual thing I've noticed with the laptop is that the CPU fan wants to run at full speed all the time, even though the computer is never used for any "processor-intensive" tasks. The normal activity on it is browsing the web, watching videos, playing music, writing text files and really nothing more than that.

I immediately found this odd and I have come to the conclusion that something in Windows 10 is responsible because:

a) This never happened in Windows 7, which was the previous operating system the computer had, and

b) This doesn't happen when I start the computer and go into a different operating system, namely Ubuntu.

Performance :: CPU Speed Locked - Usage Never Goes Above 47%

Aug 4, 2015

This started back when I was running Windows 8.1, so it isnt new to the Windows 10 installation. Every now and then my laptop will get really slow. When I look at the task manager, I will see that CPU usage never goes above 47% and it seems like it is speed locked to 1.19 Ghz.

Dell Latitude E4310
Core i5 540M @ 2.53 Ghz, Turbo to 3.06 Ghz
8GB RAM
180 GB Intel 330 Series SSD
Windows 10 Professional

Those are the specs. This happens even right after a clean install with absolutely nothing else on it except for what comes with Windows. Ive looked into the BIOS to make sure those settings are valid and Ive looked into the power options under windows to make sure something isn't weird there.
