100% CPU Usage After Windows Update?
Jul 5, 2012
About a month ago my HP laptop began running very slow when I played any type of video. When i looked the CPU was at 100%. This could be a dvd, netflix, utube, flash, media player. It would continue to run slow after any of these applications were closed. If I restarted or let it go into sleep mode it would operate fine until I started a video of some sort. Ran every virus and malware program under the sun and no problems found. To rule out a hardware issue I restored the laptop to "out of box" state. Initially everything seemed fine. I played a dvd for 45 minutes and it was fine CPU never went about 10%. Satisfied that my virus was gone i started doing the windows updates. Tried to play a video last night and the CPU usage is back to 100% when i put in a dvd. HP dv7, i7, 8gb RAM.

Just today I decided to update my IE8 to IE9 (Win 7). There was also an unknown windows update to install (today 15th Jan 12)). As soon as it was installed (without even opening IE) my system is now using 25% more ram (about 700 of 1G compared to around 500 before). I uninstalled IE9 and went back to 8 as shown on the microsoft page, but as soon as i start windows its using 700 again. I tried rolling back to an earlier point today and still have super high ram usage. Now with just this single IE tab open im using 900!

I have had my laptop for around a year now, and it's always been pretty fast for a cheapish laptop, It's an advent modena m100 in blue, but recently it has started getting real slow, like my CPU Usage is at 100% all the time and my Physical memory usage is running quite high aswell, without even having any programs open.

When I first boot up the machine and start using it (win 7 ultimate 64bit) the memory usage stays arround 40%. If I keep using it, the memory usage will slowly increase until it reaches 99%. If I boot up the machine and just leave it there for a couple of hours, the same happens.I try to restart (via windows), it logs off, shuts down the system, the coolers keep spinning, the motherboard lights are still on, but it doesn't boot up again. It remains like that. I have to restart via reset button or power button.

If I am surfing the net or looking up something on the net, my computer will almost come to a stop and get very very slow, when I go to the task manager, I find the CPU usage at 100% and just stays there. When I look at the processes there are several that are high (DWM.exe (20-23%, Taskmgr.exe, FireFox.exe

My Audiodg.exe process is currently using 2,786,070 kB (not just normal bytes, kilobytes) of Ram. 2.66gb+ of Ram! I have searched the web as well as this site for any problems. My audio is working fine though... I have no idea why this using so much ram. Im guessing a memory leak of some kind... I restartand it starts off at a normal pace...

I'm out of ideas. I've been running Win 7 on this machine for more than a year without issues in updating etc. Now it will not search or update/install critical items. I'm running Symantec (even tried turning the firewall off without any success). I get an error code 80072F7C. When I run hijackthis, I get an error message that my system denied write access to the Hosts file. I proceed with the scan but am unable to produce a log file. I've included a screenshot from the windows update error as well as the error I get when trying to run hijack this.

The update is called:
nvidia - Graphics adapter WDDM1.1, Graphics Adapter WDDM1.2, Other hardware - NVIDIA GeForce GT 425M.
After installing it, whenever my laptop tries to use the Nvidia card, I get a blue screen and the system restarts. I looked in installed updates to uninstall it, and it is not there. I did a system restore to four days before I installed it, and I still get the same effect. Lastly, I installed some older nvidia drivers that used to work using the clean install option, and I still have this problem.

A while back, after successfully downloading and installing some updates in the Windows Update, it prompted me to restart the computer to finish the update installation process. However, I continued to use the computer for quite some time before restarting it, and then when it tried to configure the updates on the start-up screen, it showed that it was not successful in doing so. In the past, I noticed that this would typically happen when I did not restart the computer immediately (or within a short time) after the updates finished and I got the prompt to restart. I would have to go to Windows Update and do it over again, and then upon immediate restart, it would always work properly. But this time, it did not, and I keep getting the 8000FFFF error message instead.
Also, now, every time I start the computer, it shows that it's "Preparing to configure Windows... Do not shut off computer" (presumably the updates that never got completely and correctly configured) in the start-up screen... gets to 35%..fails... shuts down (screen goes black)... restarts again... tries to configure again, fails again, shuts down and restarts again... tries to configure again, fails again, and finally it apparently gives up and says "reverting changes" and finally goes to the desktop.I've looked at the answers in several threads at the answers.microsoft.com forum that were started by people with similar problems, and also tried several of the Microsoft "FixIt" files on the Microsoft site, but none of them worked. I'm using Windows 7 Home Premium.

My windows update does not like to load! It takes a very long time and sometimes causes explorer to crash! When I checked, I had 92 updates to install. When I click download and install, it would freeze and stay there for a long time. I tried to use the Fix it application, however that gets stuck on "Checking Online for Updates" as well! What should I do? I also tried to update in safe mode, but it wouldn't let me.

My Windows 7 laptop has recently been through about a half-dozen supposed "fixes" to malware and registry repairs. It is still running high CPU cycles. How can I fix it (preferably without paying for anything)? I have AVG and will purchase their PC TuneUp when I get a chance, and I just bought SpeedyPC earlier tonight.So, I don't want to spend more money. I have tried Spybot, Malwarebytes, and another one (can't remember).

I recently purchased a small laptop (ASUS X43U increased RAM 4GB) and only in the past 2 weeks or so the CPU usage has been fluctuating up to 100% and as low as 4% ish. The computer is making this horrible noise all the time (I've been told its the cooling fan..) and is driving me insane. I have a fully up to date antivirus software, no games or additives installed, and really only ever have 1 or 2 windows of Google Chrome open at one time.

Recently installed the 64 bit Windows 7 beta, and my CPU usage is constantly at or near 100%, even with no external programs running. Just to give a quick run-down of my system, I have:-- AMD Athlon 64 3200+ Processor (2.2 GHz)-- 2GB DDR RAM-- 1GB Diamond Radeon 3650HD Video CardThe rest of my setup is a basic desktop machine -- plenty of storage space, etc. It runs XP Professional (32-bit) just fine. I installed the Vista x64 driver for my video card last night; it installed successfully, but did not seem to help much.

My computer memory usage is @ 100%. I have started my computer in safe mode and ran malware & panda antivirus to clean up my computer. When I reboot it runs great; however, the second time that I reboot-- it starts the memory usage @ 100% again. This is a vicious cycle.

I am currently not having any issues with XP and everything is working fine for what I use this computer for. That being said and considering my set up is an upgrade to Windows 7 worth it? Is Windows 7 really that big of an improvement over XP? The only thing that is even making me consider an upgrade to Windows 7 is for the chance to use DirectX 11.However, I've read that some older setups are having a hard time getting Windows 7 to work correctly because many of the necessary drivers needed for the computer to operate correctly are no longer supported. I know for a fact the last updates that were released for my BIOS and my motherboard chipset were in 2006. Will they even work in Windows 7?

My computer uses 95-99% RAM everyday even with no windows open. It's very annoying because it cause the computer to run very very slow. I currently have an Acer Aspire 7540 with 2 or 3 GB of ram. Task Manager currently says I'm using 2.69 GB.

I have just bought a new computer. It has Windows 7, 2.67Ghz i5, 450GB HD, and 4GB RAM. I am getting crazy surges in my Memory usage. I have been reading that the bloatware that comes with the computer (sony vaio stuff) can contribute to this (you may notice there are 99 processes). This surge (picture) occurred when I opened chrome but it was listed as using up around 25MB, which was also the largest program by memory usage. Can someone please explain how I can lower my memory usage? It has surged to 100% a couple of times before and i have only had this computer for 2 days! The computer averages 65% when I am simply surfing the web.
